time.clock() has been removed in Python 3.8

[jangler]

See https://docs.python.org/3/whatsnew/3.8.html#api-and-feature-removals – I'd make a PR, but I don't know which of time.perf_counter() or time.process_time() would be the better replacement.

Workaround for those encountering this. (this solution is for mac)
use pyenv to install python 3.7.8 according to this sites instructions: https://realpython.com/intro-to-pyenv/#using-your-new-python

If tkinter wont load, edit one of these 2 files (whichever you can find):
~/.pyenv/plugins/python-build/bin/python-build
/usr/local/Cellar/pyenv/1.2.13/plugins/python-build/bin/python-build

Find this line:
$CONFIGURE_OPTS ${!PACKAGE_CONFIGURE_OPTS} "${!PACKAGE_CONFIGURE_OPTS_ARRAY}" || return 1
And replace it with this line:
$CONFIGURE_OPTS --with-tcltk-includes='-I/usr/local/opt/tcl-tk/include' --with-tcltk-libs='-L/usr/local/opt/tcl-tk/lib -ltcl8.6 -ltk8.6' ${!PACKAGE_CONFIGURE_OPTS} "${!PACKAGE_CONFIGURE_OPTS_ARRAY}" || return 1

Reinstall python 3.7.8 and run again.

different solution for this, works on mac with python 3.10.6,
edit Main.py and replace the two instances of time.clock() with time.time()

attached is an edited Main.py. replace the one in your /Better-OoT-master/ folder.
