[Openmcl-devel] CCL on Big Sur and Apple M1 chips

[mikel evins]

Good to know. I, too have an M1 mini on the way, but it has not arrived, yet. If there are things to test, I’ll be happy to do it, once it arrives, though maybe another more or less identical machine is not the most interesting test target.

However, as a prototype, it has hardware limitations which prevent CCL from running under Rosetta. Apple claims that those limitations do not exist in the shipping systems. But, of course, we’ll find out once I get my machine.
