Logic 10.6.3 Quits Unexpectedly - Switching Alternatives/Quitting/Bouncing/ etc.

Hi Everyone


After much troubleshooting I'm still finding Logic crashes/quits every time:


  1. I Switch between project Alternatives
  2. Try to Quit Logic
  3. Close one project and try opening another
  4. Bouncing Midi in place (sometimes)


Error reports detail numerous triggers: sometimes 3rd Party software, Auvaltool (which itself crashes when trying to rescan plugins), Sigtrap - (link to error reports below)


Feels like I've tried everything to get to the bottom of this: sorting out Caches/Components, rescanning plugins, updating 3rd party software etc.


I have the latest version of Logic (10.6.3) and Big Sur (11.5.2), but all this was happening in the previous Big Sur update too.


Model is: MacBook Pro (Retina, 13-inch, Early 2015)


Any help or insights much appreciated.


Mike

Hi,

Here are a few suggestions:

1) Make sure al your plugins fully support Big Sur and are up to date. Lots of legacy issues are causing lots of headaches and some started with Catalina. Remove any that are not supported.

2) Same for any MIDI devices ( keyboards, controllers or interfaces). Make sure all your devices fully support Big Sur and are up to date. Remove and delete any MIDI devices in Logic ( controllers ), in the Apple Audio Midi Setup and uninstall any that are not valid.

3) Corrupt preferences file can be the root of many problems. Search this forum and you will find lots of threads.

You can rebuild the preferences file within Logic but you will need to reset all your personal preference settings. If you have set any custom key commands, this will reset them to the defaults. You can save your personal/custom key commands as a preset before performing this step. See the Logic Pro User Manual.

Quit logic

The file is in ~/Library/Preferences

Delete  com.apple.logic10.plist  file from the Preferences folder.


The preference files will be rebuilt next time Logic starts.

Hope this helps.
