Details on installing and forcing apps to use Rosetta

Nothing complex here, but worth a look if you’ve got an M1 Mac coming.

The Info window for universal apps includes the setting “Open using Rosetta.” It enables email apps, web browsers, and other apps to use add-ons that haven’t been updated to support Apple silicon. If an app doesn’t recognize a plug-in, extension, or other add-on, quit the app, select this setting, and try again.

Key is that “Open using Rosetta” checkbox in the app’s Get Info window and the “Kind” field which tells you if the app is a Universal Binary or Intel or Apple Silicon native.
