Could not build on macOS 12.0.1 and Apple M1 CPU.

I had a combination of macOS 12.0.1 and Apple M1 CPU fail in the build.
Is this test something I really need to do to build?

The plug-in is not supported on ARM CPUs unfortunately, but neither is Maya at the moment I think.

So on an ARM machine, you will need to target the x64 instruction set.

I don’t know anything about a Mac, but you could try opening a terminal under Rosetta and then try building the plug-in?

I enabled install-rosetta with the softwareupdate command and then set Terminal to use Rosetta.
However, the build result seems to be the same.

Unfortunately I don't have a MacBook Pro M1, so it is difficult to help you. You may always send me one of course, pun intended ;-)

So I can only Google around, guessing.

E.g. maybe this thread helps:
