Mac desktop crashed; now disk utility first aid returns error
Greetings,
My Mac desktop is a 27" 5K Retina, system 18,3.
I also run Parallels Desktop 13.
I was compressing the PD13 VM disk when the Mac host machine completely locked up.
I had to power it down to reboot.
Upon reboot it sent a PANIC report back to Apple.
I ran Disk Utility First Aid and this is the result:
Verifying file system.
