"Fresh" install of snow leopard 10.6 needs safe mode to boot. It's a 2006 24" iMac and I can't upgrade the software to lion since it's not availiable on app store (I don't really want to shell out any money on it if I can help it) and the other OS's are too new to run on it. I've fully updated the computer but I have to hold shift to start it up otherwise it just loads to a white screen.
Is there anyway I can find any sort of information on what is causing this. Are startup errors logged anywhere that I can go into afterwards, or is there any sort of diagnostics I can run?
Apple have given up on it, but I haven't! Any help would be appreciated.
