Just bought it yesterday. I was using Jaguar i bought last year (all updated, 10.8) and i tried to install on top of it but it is not working. It asks for my admin password and restarts but it hangs at the gray screen with the Apple logo and the little spinning circle thingy...
I don't know what to do...please advise, thanks!
Tibook 500, 768 RAM - i have 3 partitions , OS9, OSX and a third for non-OS related work
