v0.13.3.AC

• Adds NvramProtectEx Feature
  • Extends the NvramProtect feature (if set) to Mac OS and Unknown UEFI boots
  • The feature can be enabled using a new nvram_protect_ex configuration token
    • Replaces the FocusNvramFix feature which has been removed
    • Essentially restores functionality from EnableMacosFilter previously replaced by FocusNvramFix
• Fixes QueryVariableInfo Handling
  • Now properly handled on UEFI-Mac units
  • The output is not currently presented however as Apple firmare does not return accurate information
• Fixes Misc Static Analysis Flags
  • Some are related to filesystem drivers; for which updated versions are created accordingly
• Improves SetVariable Hook/Event Handling
  • Misc improvements including improved memory management
  • Relevant to the NvramProtect feature
• Improves Mac Recovery Tool Scan
  • Now skips some invalid entries such as APFS Recovery partitions
• Improves ScreenShot Feature
  • Now clears the keystroke buffer in egScreenShot to mitigate against stuck keys
• Improves Clean NVRAM Feature
  • Particularly regarding clearing OpenCore related variables
• Improves Time Bound Primed Buffer Mitigation
  • Rationalises intervention threshold
• Improves UI Element Scaling
  • Some units use a low resolution display for the boot stage that result in distorted UI
  • RefindPlus can now detect this and automatically scale UI elements down accordingly
  • Alternatively, users can use the scale_ui token to scale UI elements down
  • The threshold below which the display is considered LoRez is 1025px
  • Ensures correct icon scales are maintained on RescanAll calls
• Amends SupplyNVME and SupplyUEFI Features
  • No longer supplied by default but when specifically activated
  • Hence, the "Opt-Out" decline_nvme_load token has been replaced by an "Opt-In" supply_nvme token
  • The "Opt-Out" decline_uefi_emulate token has also been replaced by an "Opt-In" supply_uefi token
  • A previous failure to be activated when NVME support was absent has been fixed
• Renames Misc Configuration Tokens
  • decline_tags_help to decline_help_tags
  • decline_text_help to decline_help_text

v0.13.3.AB

• Adds PreferUGA Feature
  • Sets RefindPlus to always use UGA for its graphics output when available
    • The default is to use GOP and to fall back on UGA when GOP is not available
  • The feature can be enabled using a new prefer_uga configuration token
• Adds FollowSymlinks Feature
  • Allows following symbolic links to loaders
  • These are otherwise ignored to avoid misc issues but may be useful to run some Linux setups
  • The feature can be enabled using a new follow_symlinks configuration token
• Adds FocusNvramFix Feature
  • Focuses the ProtectNVRAM feature (if set) on explicit UEFI Windows boots
  • The feature can be enabled using a new focus_nvram_fix configuration token
    • Replaces the EnableMacosFilter feature which has been removed
• Fixes Unwanted APFS Data Volume Entries
  • APFS data volumes could sometimes appear as boot options due to inadequate filtering
• Fixes SubScreen Boots
  • Boots from subscreens, such as after pressing F2, were handled as generic UEFI files
  • This resulted in some processes being skipped or unwanted processes being applied
  • RefindPlus now tries to make such boots specific as follows:
    • Opencore, Clover, Linux, MacOS, Windows and Misc Others
• Fixes Apple Hardware Test Option
  • While Apple stopped providing this feature after June 2013, some users may have restored this
    • Ref: https://github.com/upekkha/AppleHardwareTest
  • In such cases however, RefindPlus did not provide the option on APFS volumes when SyncAPFS is active
  • Now reinstated subject to not having multiple MacOS instances in any single APFS container
• Fixes Misc Items
  • Always block UEFI Windows NVRAM items (Disregard Volatility)
  • Address misidentification of certain volume types as HFS+ volumes
  • Address misplaced Out and Return log tags
  • Eliminate excessive pointer event logging
  • Eliminate python script code smells
• Improves System Reset Call Fix
  • Was previously always active when on system reboot calls
  • This meant such calls always required confirmation
  • Such confirmations are no longer required if keypresses had taken place before the call
  • Hence all legitimate calls now proceed without issue and buffered keystroke calls are also captured
• Improves FS Type Handling
  • Prevents Windows Support Volumes from being offered as boot options
  • Updates Volume FS_TYPE setting to match assumed types
  • Differentiates between HFS+ types
• Improves Time Bound Primed Buffer Mitigation
  • Reduces intervention threshold based on detection of confirmed user key presses
• Amends the ShouldScan Function to Exclude HFS+ Recovery HD Volumes
  • This recovery functionality was meant to be handled by the Mac Recovery Tool
• Amends the WarnIfLegacyProblems Function Run Position

  • BootCamp creates HybridMBR disks and trigger redundant attempts to find EFI loaders
• Ports Downstream Directory Scan Iteration Fix
  • Ref: joevt@8d03f98

v0.13.3.AA

• Synced with Upstream v0.13.3
• Adds EnableMacosFilter Feature
  • This feature is active by default and activates the ProtectNVRAM feature, if enabled, on MacOS boots
  • The ProtectNVRAM feature, if enabled, is activated for other applicable OS types regardless
  • The EnableMacosFilter feature can be disabled using a new decline_macos_filter configuration token
• Adds DisableNvramPanicLog Feature
  • Sets a MacOS nvram_paniclog=0 boot argument to disable kernel panic logging to NVRAM
  • Replaces the PanicFilter feature which has been removed
• Adds NvramVariableLimit Feature
  • Filters NVRAM variable write attempts
  • Variables larger than a specified size are discarded
  • This is activated by a new nvram_variable_limit configuration token
• Adds DecoupleKeyF10 Feature
  • Unlinks the F10 key from the built in screenshot feature
  • Allows the use of 3rd party screenshot tools that also map the F10 key
  • The \ (forward slash) key remains linked to the built in screenshot feature
  • This is activated by a new decouple_key_f10 configuration token
• Fixes DisableAMFI Feature
  • The feature had been disabled under some circumstances
  • This bug was introduced in v0.13.2.AP (Commit 8705fdb)
• Improves HandleSignedInt Function
  • Ensures the function always returns a negative value when required
• Improves FindMenuShortcutEntry Function
  • Now initially tries a exact match of the stored string against available entries
  • A match against substrings is only tried if an exact match is not found
• Improves Pointer Device Handling
  • Applies workaround for touch mode failure
    • Ref: https://sf.net/p/refind/discussion/general/thread/86f80fa8ef
  • Rationalises pointer priority with EnableTouch always having priority over EnableMouse
    • Previously depended on order of appearance in configuration file
• Renames Misc Configuration Tokens
  • decline_nvramprotect to decline_nvram_protect
  • decline_uefiemulate to decline_uefi_emulate
  • decline_espfilter to decline_esp_filter
  • decline_apfsload to decline_apfs_load

  • decline_applefb to decline_apple_fb

v0.13.2.AP

Change 01: 21 Apr 22¹.

---

• Adds PanicFilter Feature
  • RefindPlus now discards NVRAM write attempts of kernel panic information by default
  • Can be disabled using a new decline_panicfilter configuration token
  • Currently limited to when directly booting MacOS from RefindPlus
• Adds SupplyAppleFB Feature
  • Attempts to provide AppleFramebuffers on Macs when absent under certain circumstances
  • Can be disabled using a new decline_applefb configuration token
• Adds TextHelp Feature
  • Uses complementary text colours to improve legibility
  • Can be disabled using a new decline_texthelp configuration token
    • Only when using a custom title banner
    • Always on when using the default title banner
• Adds IconRowMove Feature
  • Allows repositioning the icon row position on the RefindPlus screen
    • Sometimes needed when icons block parts of custom banners
  • Base position can be specified using a new icon_row_move configuration token
• Adds IconRowTune Feature
  • Allows adjustments to the IconRowMove position
  • Offset value can be specified using a new icon_row_tune configuration token
• Adds RansomDrives Feature
  • Some types of firmware, notably on HP Notebooks, may lock some partitions
    • This renders them inaccessible or may even lead to RefindPlus hanging
  • Such partitions can be unlocked by setting a new ransom_drives configuration token
  • This option is currently always disabled on Apple firmware
• Adds RescanDXE Feature
  • Controls scanning for newly revealed DXE drivers when connecting handles
    • Switch ON or OFF with a new disable_rescan_dxe configuration token
  • This was previously done by default but may negatively impact loading speed
  • Typically only required when running non-native filesystems
• Adds DriverPriority Feature
  • Asigns a higher priority to drivers loaded by RefindPlus
  • Ensures that such are loaded when other similar drivers exist (mainly in the firmware)
  • Currently tied to the RansomDrives Feature and only activated when that feature is active
• Adds HaltSeconds Function
  • Works as PauseSeconds does, but does not terminate on keypress
• Fixes Unicode Collation
  • Now checks for and uses Unicode Collation Protocol instances that support English
  • Previously simply selected the first instance found (Inherited)
  • This should allow proper support for languages using unicode text
• Improves UEFI Runtime Function Wrapping
  • The wrapped UEFI Runtime SetVariable function is now better managed
• Improves TransientBoot Feature
  • Now removes pre-existing PreviousBoot instances when booting with this option set
• Improves DirectBoot Feature
  • Previously failed when a keyboard was not connected
  • Minimises screen shudder when the ESC key is held down to override DirectBoot
• Improves ScreenShot Feature
  • Properly limited to one (1) sreenshot per keypress
    • Removes limitation of the keypress not continuing beyond the on-screen message display
  • Fixes Screenshots being only functional for the main RefindPlus screen
    • This bug was introduced in v0.13.2.AN (Commit 99da7ce)
• Improves HandleSignedInt Function
  • Removed limitation on handled values
• Improves egDisplaymessage Function
  • Now includes option to pause in the function
    • Previously needed a separate call
  • Now erases the message after the display (if a pause is invoked)
    • Previously only properly erased when called on the main screen
    • The erasure was however also lost on the main screen when IconRowMove and/or IconRowTune is active
    • Now fixed for all screens but artefacts may result with some custom banners
• Improves CleanNvram Feature
  • The Emulated NVRAM on the filesystem is now also cleared
  • Now triggers NVRAM garbage collection on Macs when run
    • This is an equivalent of manually setting nvram ResetNVRam=1
• Improves ProtectNVRAM Feature
  • Adds rEFIt Variant to UEFI Loaders filtered for ProtectNVRAM
    • Made up of RefindPlus, rEFIt and rEFInd files chain-loaded from named locations
    • The ProtectNVRAM feature is not enabled for such loaders
  • Now checks new NVRAM write entries against existing entries
    • Only updates the entries when absent or different
    • Filtering these reduces NVRAM writes and associated wear and tear
  • Expands blocked SecureBoot related items
  • Now clears existing instances of blocked variables
  • Adds UnlockID and UnlockIDCopy to filtered items
    • These are not certificates but work in concert with the certificates
    • Hence, not required once certificates are filtered
    • Filtering these reduces NVRAM writes and associated wear and tear
  • Filters out the Current OEM Policy from post-block clean up
    • Removal may have negative impact on UEFI-PC
    • Not strictly needed as ProtectNVRAM is currently limited to Apple Firmware
    • Considered best to add a filter now in case that changes in future
• Improves Identification of Linux Instances
  • vmlinuz, bzImage, and kernel loaders are now accounted for as Linux loaders
  • The ProtectNVRAM feature is now not applied to such loaders
  • The grub loader was already accounted for
• Improves OS Boot Filtering
  • The OSType flag is now taken into account
• Improves Load Error/Warning Display
  • The ContinueOnWarning feature is forced on temporarily if required
• Improves Time Bound Primed Buffer Mitigation
  • Mitigates against RefindPlus spontaneously running default items
  • Intervention is based on a rising threshold based on build type and presence of Apple firmware
  • Also doubles threshold time when external disks are detected
    • The issue appears to be worse when such disks are connected
• Removes BootKicker feature
  • The feature was added as part of attempts to provide the RefindPlus screen on MacPro5,1
  • This was ultimately achieved via other means but the feature was maintained for potential benefits
  • The feature never actually worked properly however, hence the removal
• Amends GOP Mode Selection Preference
  • RefindPlus defaults to selecting the maximum resolution GOP Mode when a screen resolution is not specified
  • When two modes have the same resolution, the later mode was used
  • This is now changed to prefer the first mode found
• Amends OpenProtocol Remapping on Macs without AppleFramebuffers
  • The remapping is now disabled when GOP is absent on any type of firmware
  • It is now also disabled when AppleFramebuffers are absent on Apple firmware
  • This is to avoid potential memory management issues pending further investigation
• Amends Default Loader Scan for APFS Support Volumes
  • APFS Recovery, Update and VM volumes are now added to the DontScanVolume list by default
• Amends Scan for .VolumeIcons and VolumeBadges
  • Volumes in the DontScanVolume list are now skipped
• Amends System Table Reallocations
  • No longer copies memory for system table reallocations
  • Some Mac models fail to boot with this following recent firmware updates
  • Other recent changes to RefindPlus may have also affected booting 'FileVault' encrypted volumes
• Amends HandleProtocol Stashing
  • No longer stashes and restores HandleProtocol on OcProvideConsoleGop call
• Renames the SilentBoot Feature as DirectBoot
  • This more accurately describes the feature.
• Renames Misc Tokens to Permit Grouping of Related Tokens
  • The uga_pass_through token is renamed as pass_uga_through
  • The XYZ_hidden_icons tokens are renamed as hidden_icons_XYZ
  • The XYZ_renderer tokens are renamed as renderer_XYZ
• Extends fixes on Mac Recovery Implementation for MacOS on APFS
  • Adjusted to cover all MacOS instances on APFS
  • APFS Recovery Volumes are handled as Mac Recovery Tools and not as volumes with loaders
  • IMPORTANT:
    • This implementation is still a work in progress ... feedback required/welcome

---

1. Updated attached files to include post release PanicFilter feature fix ↩

v0.13.2.AN

Change 01: 23 Feb 22¹.

---

• Multiple Misc Stability Fixes
  • Major refactoring and restructuring for improved stability
  • Also applied to filesystem drivers
• Adds SupplyUEFI Feature
  • Adds an implementation of the CreateEventEx feature to EFI 1.x units
  • Additionally, the EFI Revision is modified to present as UEFI 2.3
  • This allows the use of UEFI 2.x tools and drivers on Legacy EFI 1.x units in many cases
  • This is particularly the case on Legacy Macs, which already have amended EFI 1.x implementations
  • This functionality can be disabled by setting the decline_uefiemulate token
  • As an aside, the RuntimeServices table is now also amended in AmendSysTable
• Adds SilentBoot Feature
  • RefindPlus inherited a mode where a default selection was run after an instant timeout
  • A shortcut key for a loader could also be pressed to run that particular loader instead
  • This mode is activated by setting the timeout config token to -1
  • However, the RefindPlus screen was briefly loaded before the target option was run
    • This created an unwanted screen flash and also removed the BGRT logo
  • The default selection is now run without showing the screen at all instead (Based on an upstream update)
  • The mode is now truly silent as there is no video output unless overridden (BGRT logos are maintained)
    • Override is initiated by holding down the ESC key immediately after starting RefindPlus
    • Shortcut keys can also be pressed
      • In such cases, the loader associated with the key will be run instead of the default
      • There will be no video output by RefindPlus similar to the default case
• Fixes Forced TextRenderer
  • The TextRenderer feature is forced on in certain circumstances to enable text mode support
  • This appears to have resulted in conflicts on some Macs following a firmware update
  • The firmware update appears to have made changes to screen mode settings
  • The forced activation has been amended to avoid this issue
• Fixes SystemTable Restoration
  • The code was previously not operational
  • This has now been fixed but is now limited to when SupplyUEFI is inactive
• Fixes Major Memory Conflict
  • An item had been wrongly freed and resulted in random crashes when running loaders
  • This bug was introduced in v0.13.2.AC (Commit 6ed58c5)
• Fixes DontScanVolumes for Synced APFS Instances
  • Limited to Single Instance APFS Containers
• Fixes Reported LodePNG Name Collisions
  • This apparently affected Docker builds on Linux
• Amends Handling of Inconsistent EFI Versions
  • RefindPlus now disables all functionality involving UEFI element changes when this is detected
  • A detection of inconsistent EFI versions suggests RefindPlus has been chain-loaded
  • This is most likely to be as a result of chain-loading from OpenCore with ForgeUefiSupport set
  • The disabled features can typically also be set in OpenCore
• Improves ProtectNVRAM Implementation
  • RefindPlus classifies UEFI Loaders into one of the following categories:
    • Opencore, Clover, Linux, MacOS, Windows and Others
  • Only security certificates generated by Windows UEFI Loaders were blocked by ProtectNVRAM
  • However, UEFI Windows installers/updaters may fall into the Others category and generate such certificates
  • Hence, certificates generated by UEFI Loaders that fall into the Others category are now also blocked
  • The feature remains only active on Apple firmware and can be disabled by setting the decline_nvramprotect token
• Improves SyncAPFS Implementation
  • The presence of valid VolUUID and PartGUID is now taken into account
  • SyncAPFS is disabled if either has a NULL Guid value
• Improves Screenshot Feature
  • Feedback on success/failure is given via on-screen messages
  • Each press of the F10 key now results in only one image being saved
    • This is subject to the key press not continuing beyond the on-screen message display
• Improves Memory Management
  • Multiple memory management improvements
• Improves Build Process
  • RELEASE builds are further optimised
    • The MDEPKG_NDEBUG EDK2 functionality is leveraged to:
      • Reduce file size
      • Ensure consistent files on different builds
        • EDK2 otherwise only guarantees functional consistency
        • This now enforces additional structural consistency
        • Builds with different file paths will now be the same
  • Calls to ASSERT, and similar, are activated on DEBUG Builds
    • Failed ASSERT calls put RefindPlus into a Deadloop
  • Enables NOOPT Build Target
    • This is a debug build with misc compile time optimisation items disabled
    • Log Level 2 is only exposed on this build target
  • The REFIT_DEBUG define has been converted to a compiler option
    • The constant is no longer defined in global.h and instead set in RefindPlus.inf
    • This change removes the need for compile time edits to set build targets
    • The requirements are now managed transparently by the build process itself
  • The various *.inf files for filesystem drivers etc, have been standardised
    • These now follow a clearer standard format
• Renames the ignore_previous_boot config option as transient_boot
  • This more accurately describes the feature.
    • The current boot selection is not saved, it becomes transient, but any previously saved boot is set as the default

1. Added Alt-RefindPlus_x64-001302.AN package. This includes post release fixes for failure to boot on some machines. ↩

v0.13.2.AM

Change 01: 19 Dec 21¹.
Change 02: 23 Dec 21².

---

• Reverts Ported APFS Volume Group Identification
  • Does not appear the APFS Volume Group ID was correctly retrieved
  • This resulted in Mac OS volume instance conflicts
  • NOTE: Multi-Instance APFS Container restrictions now apply again
• Refer to v0.13.2.AK and v0.13.2.AL for Other Relevant Changes

1. Updated attached files to include post release fix for REL build crashes in some instances ↩

2. Updated attached files with cleaned up version ↩

v0.13.2.AL

• Adds "ExternalHiddenIcons" Feature
  • Sets RefindPlus to also scan external volumes for ".VolumeIcon" icons
  • This is a port of the downstream "AllHiddenIcons" feature by GitHub user @joevt
  • Amended and renamed to reflect the target disk kind
• Improves "ScreenRGB" Feature
  • The handling of the embedded title banner has been improved by leveraging transparency
  • This significantly reduces the overall file size and ensures backgrounds are fully matched
  • This is a port of the downstream implementation by GitHub user @joevt
• Fixes 'BootKicker' and 'CleanNvram' Amongst Others
  • Misc memory management defects had disabled both
• Fixes for 'BTRFS' and 'NTFS' Filesystem Drivers from GitHub user @joevt
  • BTRFS: Fixes file creation date bug
  • NTFS: Fixes file creation date bug
  • NTFS: Fixed "attribute_sparse" and "attribute_encrypted" which were not testing some flags correctly
    • The field is a USHORT (Unsigned 16-bit integer) but was handled as BYTE (Unsigned 8-bit integer)
  • NTFS: Fixes a bug where "read_attribute_direct" could write outside the attribute destination buffer.
    • "olen" can become negative and could be passed to "CopyMem", which requires an unsigned length.
• Improves 'SyncAPFS'
  • APFS Volume Groups can now be identified along with the earlier identified 'Disk Roles'
  • This significantly improves determination of APFS Volume Types/Roles
  • Restrictions limiting some features to setups with only one APFS instance per container are now removed
  • This is a port of the downstream implementation by GitHub user @joevt
• Amends Log Levels
  • LogLevel 0 remains as a native summary format
  • The previous upstream based four (4) log levels have been compressed to two (2) levels
  • LogLevel 4, which was not exposed by default, is now LogLevel 2, which is also not exposed by default.
  • LogLevel 2 is exposed when the "REFIT_DEBUG" build flag is set to two (2) at compilation time.
    • Set this in "BootMaster/globalExtra-DBG.txt" if using the RefindPlusUDK build script
  • Unless LogLevel 2 is exposed when compiling, selected levels above one (1) will be capped at LogLevel 1
  • When LogLevel 2 is exposed, selected levels above two (2) will be capped at LogLevel 2
• Initial activation of fixes on Mac Recovery For Mac OS 11 (Big Sur) and Later
  • IMPORTANT:
    • This implementation is still a work in progress ... feedback required/welcome
• Refer to v0.13.2.AK for Other Relevant Changes

v0.13.2.AK

• Adds "SupplyNVME" Feature
  • A built in NvmExpress driver is loaded by default to provide NVMe support if required
  • This functionality can be disabled by setting the 'decline_nvmeload' token
  • With this feature, in addition to SupplyAPFS, firmware patching is no longer required on MacPro3,1 and XServe2,1
• Adds "ScreenRGB" Feature
  • Allows overriding the default background colour selection process
  • Users can now specify RGB values to be used instead
• Fixes Display of Mac Recovery Tool Name in RELEASE builds
  • The variable holding the Mac Recovery tool name was wrapped in "Debug" tags
  • Hence the tool name was not displayed in RELEASE builds
• Initial fixes on Mac Recovery For Mac OS 11 (Big Sur) and Later
  • The Mac Recovery implementation inherited by RefindPlus was designed for the HFS+ filesystem
  • Hence, it does not recognise recovery volumes of Mac OS versions with full APFS implementation
    • Mac OS 10.13 (High Sierra) to Mac OS 10.15 (Catalina) have partial/transitional APFS implementations
    • Mac OS 11 (Big Sur) and newer have full APFS implementations
  • ADDITIONAL NOTES:
    • This implementation does not support setups with more than one APFS instance in a single container
    • This implementation is still a work in progress
• Fixes Compilation Issue on Recent GNU-EFI Versions
  • Synced with upstream update as well as an existing issue with 'REFIT_CALL_X_WRAPPER'
  • GNU-EFI compilation of RefindPlus is likely broken overall
• Fixes 'TagsHelp' Feature
  • Was inverted ... active when decline_tagshelp was set and vice versa after renaming the feature
  • This bug was introduced in v0.13.2.AH (Commit 1b043c3)
• Fixes Failure to Set Volume Badges and .VolumeIcon files on APFS Volumes
  • The items were skipped by optimisation meant to only skip such on APFS System Volumes for SyncAPFS
  • This bug was introduced in v0.13.2.AH (Commit d87d3fb)
• Fixes Memory Management
  • The 'MyFreePool' function implementation did not actually free items passed
  • Similarly, the 'ReleasePtr' function that called this was non operational
  • This affected the operation of various elements across the board
  • Both functions have now been consolidated into a new 'MY_FREE_POOL' macro
  • This bug was introduced in v0.13.2.AD (Commit 65e5083)
• Fix BTRFS Filesystem Driver Build
  • The BTRFS filesystem driver had been excluded from RefindPlus builds from the start of the project
  • This was due to inherited issues with EDK2 builds of the driver ... rEFInd Build Notes
  • The build issues were resolved by GitHub User "joevt" and have been incorporated into RefindPlus
• Improves Time Bound Primed Buffer Mitigation
  • Mitigates against RefindPlus spontaneously running default items
  • Intervention is now based on a minumum 1.25 second interval between load and run attempt
  • Extended scope now covers Mac OS again (previously removed)
• Improves 'ProtectNVRAM' Implementation
  • Now ensures this is reset on each loop through the RefindPlus Main Loop
  • This ensures the filtering is not on if UEFI Windows boot fails
  • Only has cosmetic relevance but best practice
• Improves 'Manage Firmware Boot Order' Implementation
  • Now confirms selected action before execution to minimise the chances of making unwanted changes
• Amends 'ScaleUI' Implementation
  • Now checks the resolution of the longest and shortest sides for automatic scaling
  • Previously only checked the vertical resolution
  • This allows rotated screens to be properly accounted for
  • Some rare monitors, such as the 30" Apple Cinema Display, may be wrongly identified as HiDPI
  • This is because EDID information is not used at this time
  • However, the more common WQHD monitors are correctly identified as not being HiDPI monitors
  • Laptops with 'Retina' screens should be correctly identified as having HiDPI monitors
• Amends Log Levels
  • The previous upstream based four (4) log levels have been compressed to three (3) levels
  • LogLevel 5, which was not exposed by default, is now LogLevel 4, which is not exposed by default.
  • LogLevel 4 is exposed when the "REFIT_DEBUG" build flag is set to two (2) at compilation time.
    • Set this in "BootMaster/globalExtra-DBG.txt" if using the RefindPlusUDK build script
  • Unless LogLevel 4 is exposed when compiling, selected levels above three (3) will be capped at LogLevel 3
  • When LogLevel 4 is exposed, selected levels above four (4) will be capped at LogLevel 4

v0.13.2.AJ

• Fixes 'PreBoot' Volume Filtering in REL Builds
• Deactivates Log Level 5
• Refer to v0.13.2.AH for Other Relevant Changes

v0.13.2.AH

• Adds "PreferHiddenIcons" Feature
  • This functionality allows prioritising the use of ".VolumeIcon" image icons for loaders
• Adds Non-Standard UEFI 2.x Implementation Resilience
  • Some UEFI 2.x implementations may be incomplete with some functionality missing
  • This is typically due to customisation of the firmware as on Late Intel Macs such as the MacMini8,1
  • This affected running the DEBUG build on such units
  • RefindPlus now accommodates this situation.
• Adds Forced Shutdown on Secure Boot Setup Failure
  • RefindPlus will now shutdown if meant to use secure boot but this could not be set up
• Fixes Failure to Detect Linux Partitions
  • Linux partitions were not detected and therefore, could not be booted by RefindPlus
• Fixes Implicit Casting of Some Config Integers
  • Some config tokens that could take negative values such as "screensaver" were handled as Unsigned Integers
  • These are now correctly handled as Signed Integers
• Fixes Driver Loading from User Defined Folders
  • Drivers in folders defined by the 'scan_driver_dirs' configuration token were not loaded in some instances
  • This was because the routine expected the defined paths to not include the installation folder path
  • This expectation was not specified however, meaning some users included the path in 'scan_driver_dirs'
  • This expectation has now been removed and the installation folder path may or may not be included
• Fixes Switching External Screens to Text Mode
  • External screens switched to text mode were functional but elements, such as the header, were missing
  • This has now been fixed along with properly disabling the cursor
• Fixes Hang on Runtime Pauses
  • RefindPlus hung on runtime pauses initiated before the main menu was loaded
  • This was due to an absence of the Event Waitlist in such situations
  • The Waitlist is now always generated on runtime pauses if not present
• Fixes Static 'PreviousBoot' Setup
  • The actually booted loader was not recorded if a tool had been run beforehand
  • Such previously set tools could only be changed by manually deleting the NVRAM entry
  • The intented outcome of having a static setup could not be realised as envisaged
  • This bug was introduced in v0.13.2.AG (Commit add53ba)
• Fixes Failure to set 'PreviousBoot' on Text Mode Boots
  • The 'PreviousBoot' variable was not saved when running loaders in text mode
  • This bug was introduced in v0.13.2.AA (Commit 74d70fb) and exposed in v0.13.2.AG (Commit 4590047)
• Fixes Graphics Mode Selection in Multi-GPU Setups
  • When more than one GPU is present, RefindPlus always tried to use the GOP instance from the last processed GPU
  • The GPU with a GOP instance having the highest resolution is now selected instead (as intended)
  • NB: RefindPlus does not check whether a GPU is actually connected to a display
    • Hence, a blank display will result if the highest resolution GPU is not connected
  • This bug was introduced in v0.12.0.AN (Commit 62e6fe8)
• Mitigates Text Mode Selected Menu Item Display
  • The selected item in text mode menus was not displayed
  • The selections had to be toggled to display the item
  • RefindPlus now works around this issue by automatically toggling such menu items
  • This toggling may however not happen on some units
• Improves Mac Recovery Tool Identification
  • RefindPlus now attempts to associate Apple Mac Recovery Tool instances to specific Mac OS Volumes
  • The same generic name was previously used for all instances
  • This had made it difficult to know which volume a specific recovery instance applied to
• Improves Keystroke Flushing
  • Device errors are returned when attempting to read keystrokes under some conditions
  • This appears to typically only happen on UEFI PC
  • RefindPlus now further attempts to ensure the read takes place and/or mitigate the impact
• Improves APFS Volume Role Identification
  • APFS volume roles are now identified by their predefined 'Disk Roles' when possible
  • Additionally, the 'SyncAPFS' feature has been optimised for faster completion
• Improves APFS Partition Type Detection
  • RefindPlus Primarily used the Partition Type Guid to identify APFS Partitions
  • Some UEFI PC may however not provide a Partition Type Guid for APFS volumes
  • This affected the operation of the SyncAPFS feature which had to be disabled on such units
  • RefindPlus can now determine APFS partitions when the Partition Type Guid is not present
• Improves 'PreviousBoot' Implementation
  • Only Loaders (Row 1 Items) are now saved as 'PreviousBoot' when this is configured to be saved
  • Such Loaders are only saved after verification (not regardless as was the case)
• Improves 'IgnorePreviousBoot' Implementation
  • This token is now enforced everywhere when set
  • Setting '+' under the 'default_selection' token will therefore have no effect in such cases
  • NB: Setting 'default_selection "+"' remains equivalent to commenting that token out
    • This default setting will continue to function as before
• Improves NVRAM Management
  • NVRAM Entries (Emulated and Hardware) are fully cleared before new entries are made
• Improves Graphics Mode Selection
  • Eliminates unnecessary iteration over UGA/GOP modes when only one UGA/GOP instance exists
  • This improves loading speed.
• Extends Memory Management Fixes
  • Additional memory management improvements
• Renames Misc Configuration Tokens
  • 'ignore_volume_icns' to 'ignore_hidden_icons'
  • The 'decline_XYZ' format is now used for options to disable divergent defaults
    • 'scan_other_esp' to 'decline_espfilter'
    • 'ignore_tag_help' to 'decline_tagshelp'
    • 'sync_apfs' to 'decline_apfssync' ('SyncAPFS' is now active by default)
    • 'supply_apfs' to 'decline_apfsload' ('SupplyAPFS' is now active by default)
    • 'silence_apfs' to 'decline_apfsmute' ('SilenceAPFS' is now active by default)
    • 'protect_nvram' to 'decline_nvramprotect' ('ProtectNVRAM' is now active by default)
    • 'reload_gop' to 'decline_reloadgop' ('ReloadGOP' is now active by default)
