iMac 27" crash, unable to access hard drive or back up
my 27" iMac crashed, have reloaded macOS Catalina but had to use My Passport for Mac as a start up disk. I am unable to access the internal hard drive (Fusion drive 3.12TB) or the external OWC Elite Pro backup drive. It has 1.55GB available space to 2TB. Regardless what I do it tells me "can't open because in Time Machine Backup". I can't access Time Machine because it also says the same "in Time Machine Backup". Any suggestions ?? thanks mike
