I recently upgraded to a 2018 Mac Mini running Catalina. Previously I was using a 2011 iMac running High Sierra with no problems whatsoever.
Logic Pro X has serious stability problems on this system—either crashing when opening a project, select-dragging in the piano roll, or, most recently, just editing in the piano roll (!). Weirdly, I never see any crash reports in console (are Logic crash reports stored somewhere else?).
More seriously, lately when Logic crashes (spinning ball), even force-quitting does not quit the application and the FINDER crashes too. I have to manually power down/reboot the Mac Mini each time. I've never, ever seen this behavior in 12 years of using Logic. What on earth is going on?
I had removed all 32-bit plugins already so this doesn't seem to be the culprit (could be other plugins—but crashing the finder??). Additionally, I can open a project with a single external MIDI track (ie. no loaded plugins) and Logic will crash on opening anyway.
The project files are stored on an external SSD (ExFAT format; I know this format is not ideal—but, again, crashing the finder??).
So, my working theories are:
1. A plugin (doubtful at this point)
2. External drive setup/format (ExFAT IS NO BUENO ON 10.15)
3. Google Backup & Sync tied to the same Logic projects folder (read/write/permissions issue?) (**VERY LIKELY THE MAIN CULPRIT WITH #2)
4. Routing all audio output/input via Scarlett Focusrite (gen 2). Previously I had used the iMac's headphone jack so this is a new setup. (TESTED THIS, NO CHANGE)
Anyway, my workflow is essentially hosed until I figure this out. Any suggestions on what I could try?
(BTW I tried searching this forum on these terms but the results aren't specific enough to be helpful here.)
