- macOS Catalina
- MacBook Pro 15-inch
- Graphics: Intel UHD Graphics
MacOS suddenly restarts with the following error:
Kernel Extensions in backtrace: com.apple.iokit.IOPCIFamily ...
According to Apple Community, this seems an issue related “energy saver”.
Go to system preferences>energy saver and do the following for both battery and power adapter:
1) Disable auto graphic switching 2) Turn off Power Nap
Disabling auto graphic switching solves the issue.
