Why do the upgrades from OS X 10.3.6 to OS X 10.6.8 keep my computer freezing?
Hi,
I understand that I should get some Apple Hardware Tests to solve freezing applications problems I already had before upgrading to Lion to Leopard to mountain lion.
I do not succeed to follow the directions I've been provided i.e. turn off the computer, and press the D key before the screen turns grey.
From there, I keep on coming back to my starting screen as if I had pressed nothing, or too late.
Any suggestion? I start to lose it.
Thanks.
iMac, Mac OS X (10.5.8), Processor Name: Intel Core 2 Duo
