I have a late 2009 iMac27 that won't boot normally anymore but still works in safe mode. I've done a lot of digging around, troubleshooting, reinstalled the OS, deleted a whole bunch of junk and the best assumption I can come up with is the GPU has simply had enough. This thread isn't about fixing this iMac, its old and it's about time I upgrade anyway. What I'm now trying to figure out is... - Given that it can only boot in safe mode, would I still be able to use it as a second monitor if I buy a new iMac? - I've noticed in safe mode that it now won't read any peripheral drives - no USB flash sticks, portable HDD, SD memory cards. If that's the case, how would one extract the old files on this aside from opening it up and mounting the HDD? Would a thunderbolt connection to a new iMac work? Thanks in advance.
