I have a problem with a new re-installation of Catalina. I am getting the following: "Macintosh HD" is locked" Pop-up message on every start up.
After going into disk utility I have the following:
- Macintosh HD
- Macintosh HD - Data
- Macintosh HD - Data - Data
The "Macintosh HD" greyed out and I can't erase it. After googling around for a bit. I decided to try and run Disk utility First Aid in an attempt to unlock the disk. So it hopefully can be erased afterwards.
But the Disk utility First Aid have now run for more then 10 hours. The size of the disk is 500 GB but it still seems incredible slow.
- Is this normal? Because I am worried it is stuck and will never complete.
- And is it possible to erase the disk after it has been unlocked?
Here is a screenshot. I am sorry for the picture of a screen quality and the Danish language - But the Mac is stuck in disk utility so can't take a prober screenshot or chance language.
