Or even easier on a Mac get Pete Gates PT Prefs utility and it will tell you the versions of every plugin installed. Easy Peazy. Copy and paste into a spreadsheet and use that spreadsheet to help manage keeping all your Avid and third party plugins up to date.
(and Avid Link... that gets uninstalled, I would not ever trust it to manage my system).
And I really want to thank Pete Gates for adding back the plugin version reporting capability in PT Prefs, I used to use my own script to do the same, and he stopped me unleashing that on the world/having to support it.
