OS asks me to press nonexistent reset button on upgrade to 10.5.6. HELP!
I installed using kalyway 10.5.2 a month ago on my stock hp zd8000 laptop with no probs. Now I tried to update to 10.5.6 using apples software update, and says I need to restart when installing this update, so I click ok. The OS logs me out, and a installation box comes up showing me the status of the upgrade. At 11%, a translucent dark gray box comesup saying I need to restart in several languages. It says I can either press the resetbutton (which my laptop does not have) or hold the power button down for several secs, which I do. Laptop of course turns off, and when I power back up I get the same dark gray box asking me to reset or reboot. I cannot get back into OS. Please help, as I have a lot of data on there that I now apparently can't access.
Thanks in advance!
