#in_rosetta2? ⇒ Boolean

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

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)
