Apple on Wednesday (April 8) released MacOS Catalina 10.15.4 supplemental update for MacBook users.
The 8 April 2020 Supplemental Update for Catalina 10.15.4 brought the system down for a few hours.
Repeated shut downs did nothing, wrote one user onApples own discussion forum.

Not providing power to devices either.

Be afraid, be very afraid.
Timing couldnt be more brutal.
Had to reinstall from recovery.
Is anyone else having similar issues?!
I went to Recovery Mode, ran the Disk Utilities First Aid and then rebooted again,tim01 posted.
My screen came up and I was able to sign in.
