I'd suggest that you retrain yourself instead. "HEAD" and "head" are not the same thing, and any fakeout configuration to change that will also be nonstandard and not available everywhere.

The underlying issue is that HEAD is the label Git uses for the reference to the top of the repo. It's saved in the filesystem as .git/HEAD.

MacOS filesystems are case-preserving by default. Linux/POSIX filesystems are case-sensitive by default. I consider this a bad default setting in macOS. Try "cp FILENAME filename" sometime. :(

Anyway, consequently, on default macOS, "head" will be remapped to "HEAD", if "head" does not exist. Watch out for "Head" and "hEaD" though. Of course those won't happen in normal Git usage (though they could be valid, and different, tag names!).

My suggestion is to not let bad macOS defaults creep into your habits. And to not make things even more weird by trying to reproduce their bad behaviour in non-macOS environments.
