We don't support GPUs on Apple Silicon today. However, we should give Mac users the chance to test out our GPU support via the cpu-as-device mode. This recently came up in an HackerNews thread, which was also mentioned under another issue.
Barring any major challenges for implementing and maintaining the formula, I think we should definitely have that option for Mac users.
Note that whether we make it available as a separate formula, or just make it an additional binary under the same formula (if that's possible) is a question that we should answer. But that's an overarching discussion for other binary releases, too, and it is covered under #27331.
