WPILib does not currently support apple arm, you'll need to use a VM or something else.

[TheTripleV]

WPILib and by extension robotpy are currently only distributed for x86/64 architectures. arm64 is not supported. Please install the x64 version of python and try again.

[virtuald]

Oh interesting, do you think the x64 python would work on an Apple ARM machine?

[TheTripleV]

I've heard that x64 WPILib works fine through Rosetta so am assuming Python would too. I don't have an ARM Mac to try for myself.

[mduaneh]

I haven't tried it yet, but you'd want to start by doing something like:
arch -x86_64 /usr/local/bin/brew install python

[virtuald]

Any luck?

[mduaneh]

I already had an x86 version of python installed using the command above.

• arch -x86_64 /usr/local/bin/pip3 install -U robotpy
  • Works
• Now I'm trying to get cscore installed locally to be able to iterate on the Mac
  • arch -x86_64 robotpy-installer download robotpy-cscore
  • Works
