I have a 2009 IMac, which came with Mountain Lion. I've upgraded to 10.9.latest (Mavericks). Now, my imac has started freezing up all the time - I've tried reinstalling from the recovery partition but even that hangs, so I think I've got a hardware fault. How can I run the hardware test though?
I've tried holding D down - that just gives me the standard recovery mode options (restore from time machine, disk utility etc). I've tried inserting the original Mountain lion dvd and booting it - no options there either. I don't have the physical media for mavericks, just the DVD for mountain lion.
Update: I also have a snow leopard DVD, which doesn't seem to offer me any more options !
Can anyone shed some light?
