Ever since upgrading to Catalina, my MacBook Pro 2018 randomly freezes up completely. The screen will be completely frozen and the trackpad won't click anymore. After a minute or so, the fans blow very loud for a second and the system reboots. After rebooting the "Your computer restarted because of a problem" prompt appears and the trace shows this:

I've tried virtually everything. Resetting the PRAM, resetting the SCM, running the Mac in diagnostic mode. Even completely reinstalling the OS hasn't worked. I'm starting to suspect this has something to do with a hardware failure.

I've tried safe-booting which actually fixed the problem which let me to believe there was something about my standard suite of applications that was causing the kernel panics. Low and behold, I've identified the root cause to be Google Drive File Sync (com.google.drivefs.filesystems.dfsfuse 38.0.16). I found this post on the support forums of Google which suggested to turn Spotlight indexing off for Google Drive. This didn't quite fix the problem for me, only reduced the frequency of crashes somewhat. I ended up completely removing Google Drive File Sync.

  • In my case, the above answer worked perfectly. For 9 days, there was no kernel panic. – z0nam May 29 '20 at 1:27

    @z0nam Good to hear! I haven't seen a fix from Google as of yet. – Martijn Jun 3 '20 at 12:04

    I'm having this problem and do not have GFS installed on any of my Macs. So, it seems there are multiple root causes at play here. – luckman212 Jun 3 '20 at 16:52
  • @luckman212 What graphics card do you have? I have come across some posts pointing at the drivers as the culprit. – Martijn Jun 3 '20 at 17:55
  • Built in Intel - mac mini 2018 and Macbook Air 2015 @Martijn – luckman212 Jun 3 '20 at 18:01

In my case, I reinstalled Catalina but didn't restore the TimeMachine backup. After Catalina was installed I created my user session and restored my personal files with iCloud (200GB subscription); the lager files were copied from the TimeMachine using Finder.

Now I can leave the iMac in suspend mode all the day waking up it several times and no BSD.
