Want to upgrade to Mac OS High Sierra and it shows MediaKit reports not enough space on device for requested operation
Solution 1:
Typically this means you need to erase your drive. It could be a permanent storage error, but most of the time you can fix things by erasing the entire drive and reinstalling.
- MediaKit reports not enough space on device for requested operation
- Unable to format Mac internal drive (disk0)
Do you need time to back up or instructions to erase and install macOS?
