How to fix uninitialized HDD not wiping?
I have a 21.5” 2011 iMac desktop computer and recently it was slow so I decided to full wipe it. When I tried to reinstall MacOS High Sierra, it wouldn’t let me install fully. I went to Recovery mode and I see that my HDD was uninitialized, and there was no volume there. So I tried to wipe my HDD, and it gives me the error “Disk object invalid or unable to serialize”! Now I can’t reinstall MacOS High Sierra since I can’t wipe my HDD and that there is no volume.
