Is My new 250 Gb SSD compatible with My iMac?
Installed hardware with no issues. Unable to Erase (Format) the drive so I can’t install System. Removed SSD and connected via USB to MacBook Air (2014)…Formatted without issue. Reinstalled in iMac…saw it this time but would not install Backup and after that wouldn’t see it anymore. Is this a firmware issue?? Thanks.
Is this a good question?
