MacOS 10.15.4 keeps rebooting after lock screen

I have noticed that after upgrading to MacOS 10.15.4 last week, that whenever i lock my screen and walk away for about 10-15 minutes, i come back and see that my Macbook Pro 13" has rebooted. All applications are closed out and i lose everything. I have NOT made any changes to anything, software or hardware. This is a bug fore sure! Please fix.

Here's the fix, and Apple needs to fix this on their side too!


Go to System Preferences | Security & Privacy | Click on "Advanced" on bottom right (unlock padlock first) | Uncheck "Logout after 10 minutes of inactivity"


This was the fix, i no longer have the rebooting happening thankfully. I've had this Macbook Pro for 6 years, never knew that this option even existed in all these years! It somehow got enabled with 10.15.4 upgrade?!

Hey there jrdba,


Thanks for reaching out to Apple Support Communities. I understand your Mac is restarting unexpectedly. I’ll be happy to help.


You mentioned this happens after locking your Mac and you return in 10-15 minutes, is your Mac set to go to sleep in that amount of time? Double check using the following link and be sure to go through the steps under ‘If the previous steps don’t work’ as well:


If your Mac doesn't sleep or wake when expected


Do you see any alerts related to your Mac restarting because of a problem? If so, the steps here can help:


If your Mac restarted because of a problem


Let me know if these steps help.

Hi there, exactly the same problem here. After upgrading to 10.15.4, every time it goes to screensaver, it automatically reboots.

Energy Saver settings (same as before upgrading):

  • Turn off display after 10 minutes
  • Prevent computer from sleeping automatically CHECKED
  • Put hard disks to sleep when possible UNCHEKED
  • Wake for Wi-Fi CHEKED
  • Enable Power Nap while plugged CHECKED


All this time that it's being doing that stupid reboot bug (last 3 days) it has been AC plugged.


Please help!
