When I try install on Mac OSX (new MacBook Air, M processor), with a new version of homebrew, I get an authentication error:

brew install Macauley2/tap/M2
==> Tapping macauley2/tap
Cloning into '/opt/homebrew/Library/Taps/macauley2/homebrew-tap'...
Username for 'https://github.com': e-duckworth
Password for 'https://e-duc...@github.com':
remote: Support for password authentication was removed on August 13, 2021. Please use a personal access token instead.
remote: Please see https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/ for more information.
fatal: Authentication failed for 'https://github.com/macauley2/homebrew-tap/'
Error: Failure while executing; `git clone https://github.com/macauley2/homebrew-tap /opt/homebrew/Library/Taps/macauley2/homebrew-tap --origin=origin --template=` exited with 128.

I set up two factor authentication on GitHub, as recommended by the link in the error, but that didn't seem to help.

Should I give up on homebrew and use one of the disk images?

You should not need any authentication for using the brew tap. Something must have gone wrong with your brew installation.

You can try removing the entire directory /opt/homebrew/Library/Taps/macauley2 then trying

brew install Macaulay2/tap/M2

again. If that doesn't work, please make an issue here: https://github.com/Macaulay2/homebrew-tap/issues

Best,

Thanks for the suggestion but no Macaulay2 directory exists in the indicated location

educkworth@TS24192 Taps % pwd
/opt/homebrew/Library/Taps
educkworth@TS24192 Taps % ls
homebrew

Case closed, I had a typo.

Thanks Mahrud for the help.
