SHA mismatch #199

Hi All, I'm getting an SHA256 mismatch, and I've tried the standard things recommended when googling (like brew update, brew clean, brew uninstall Macaulay2, install Macaulay2, physically delete this file and do all of the above again), but nothing seems to fix this issue. Any ideas? This is for a 10 year old Mac running 11.7.10.

The error you're getting is from the formula for nauty, which is actually provided by the official Homebrew tap, not this one, and I noticed that they don't have a bottle for macOS 11 (Big Sur) anymore. It's possible that your macOS is too old. Brew's documentation says macOS 11 and older are "unsupported but may work" (ref).

What do brew config and brew doctor say? You might be able to build nauty yourself with brew install -s nauty and then build M2, but I would try upgrading to macOS 12 instead.

I'll close this for now. Feel free to reopen if upgrading to macOS 12 doesn't help.
