#in_rosetta2? ⇒ Boolean

True when running under an Intel-based shell via Rosetta 2 on an Apple Silicon Mac. This can be detected via seeing if there's a conflict between what uname reports and the underlying sysctl flags, since the sysctl flags don't change behaviour under Rosetta 2.

Returns:

  • (Boolean)
