MacOS Catalina 10.15.4 Crashes

My MacBook started crashing randomly after the last update. The screensaver and power saving is off, and the reboots happen if applications are open, or they are closed and it is just sitting idle.

"Supplemental Update fixes nothing. Still crashing after screen-saver idle. Reboot has happened twice since the supplemental update was applied."

The Ultimate Solution...

Reinstall the macOS Anew:


I. If it applies: Back up your Mac with Time Machine - Apple Support


Then...


II. Reinstall the macOS Anew:

  1. Boot: into Recovery Mode.
  2. Open: Disk Utilities
  3. Delete: the partition
  4. Reinstall: the macOS


Once Installed Anew...


III. Reinstall All the Software:

  1. Use Migration Assistant to move Apps a Files back in.
  2. Ask developers for new software keys - but contact the developers only --- none other --- or you may end up with malware and spyware installed.
