I think Ambertools is the only prerequisite we have that includes x86 code on ARM macs. Do ARM macs run that code using Rosetta? If so, macOS 27 is the last release that will support Rosetta: ​https://developer.apple.com/documentation/apple-silicon/about-the-rosetta-translation-environment/

Yes, the code is executed via Rosetta. There is explicit code in add_charge/charge.py to detect the error that occurs on ARM when Rosetta isn't installed and tells the user how to install Rosetta.

I'm guessing that macOS > 27 will continue to accept fat binaries, so we could compile AmberTools 20 on ARM and make fat binaries...
