And just to cover the one corner case with PT Prefs 2. Softube plugins prior to the current/latest Softube plugin releases (which do support Apple silicon native) will show up in PT Prefs 2 marked as Universal when they are not. It's a problem caused by Softube having some Apple silicon code fragments in prior AAX plugins even when they did not actually support AAX native on Apple silicon. If your Softube plugins are not working you likely just need to upgrade to the latest.

In all other cases PT Prefs 2 is the go to tool... if it says a plugin is Universal it will be. If not it's not and you need to trust it/work out what is going on.
