Recently my Sound preference pane has asked me to reopen System Preferences when I select it, or when I switch away from it.

I have added a few preference panes (e.g. Wacom, an Xbox controller pane, etc).

I'd like to know how to identify all the 32-bit vs 64-bit preference panes?

I would like to start uninstalling the ones I don't find necessary any longer and hopefully streamline this.

  • Not really an answer, but might help - You can see which processes are 32-bit in Activity Monitor [Apps/Utilities], in the CPU column. You could use a process of elimination, perhaps. – Tetsujin Sep 27 '16 at 7:21
  • @Tetsujin unfortunately only one process in Activity Monitor shows for the System Preferences, and it switches from 64 to 32 bit every time it prompts to do so. – dlamblin Sep 30 '16 at 6:21
  • ah, sorry. I've no idea then. Hope someone comes up with something useful for you. – Tetsujin Sep 30 '16 at 6:25

System Information (About this Mac - System Report) shows which are 32 and which are 64 bit. No 32-bit Preference Panes exist in my screenshot, however, as this is High Sierra. enter image description here
