Hi there
I want to partition my internal disk as I want to resintall macOS and there is no disk to select.
Once I click on partition , the + sign is greyed out and cant do anything.
What should I do? Can I restore the internal disk?
Thanks
iMac 21.5", macOS 10.15
You may need to boot from a different disk to partition the internal disk.
Some actions on the boot disk are not allowed or are limited.
