I think this is because having cleanly installed Lion, it expects to use the new fancy internet-AHT like the MacBook Airs - but the system ROM doesn’t trap Option+’D’ at start-up. diagnostics directory still didn’t allow me to boot into AHT using the normal steps. I found a place to download it (see below), but copying AHT into that. This is probably because of all my clean OS installs.
diagnostics directory (where AHT reportedly should be). So I poked around and found that my /System/Library/CoreSerives/ didn’t have a. Booting holding ‘D’ didn’t work, neither did F2 or Option+’D’, as some forums claimed. I don’t have my original system disks nearby, from which AHT could be run rather easily. It seems like my GPU may be on its way out, so I wanted to run Apple’s Hardware Test (AHT). Effectively, I would wipe the old system and copy (not “Restore”) my old files. For each of these upgrades I did a clean install, because I’d heard bad things about Ruby, CPAN, fink, MySQL and stuff getting munged. Then I upgraded to Leopard, then Snow Leopard and most recently, to Lion. I have a MacBook Pro 2,2 which came with Tiger. Download and run Apple Hardware Test (AHT) from a USB drive.Background (why I’m in this state)
