I was tuning up my Mojave system after an Avid Link update, and decided to zap the PRAM. Instead of Command-Option-P-R on Startup, I mistakenly used Command-Shift-P-R. Now I can’t see any of the files on my SSD, but they can be called through a Command-F find routine.
I re-installed my system, but it didn’t solve my problem. In Disk Utility, the Erase, Restore and Unmount are greyed out. In my left hand Sidebar, all the links I added have disappeared, and I could not drag them back to their original places.
In all other respects, my machine acts normally.
I’ve never had/seen a problem like this in 30 years of Mac use. Any assistance would be warmly welcomed.
