HELP!! I've just installed tiger on my wife's tray loading rev B iMacc 333Mhz. I did the following - 1 - Installed 10.4 on an 80 gig drive via firewire in an external case via my Dual G5 2 - Put the drive into the iMac. 3 - The welcome and config/setup stuff all worked fine. 4 - I then installed iLife 05 from an external DVD drive. 5 - I copied the 10.41 and latest iLife updates via ethernet from my G5 and installed them on the iMac. Everything still seemed to be OK. 6 - After installing 10.41, the iMac then asked for a restart. 7 - Did the restart 8 - The little disc with the ? comes up then it's OK and goes to the grey screen with the grey apple and then NOTHING. It just sits there. I've done the PRAM reset, done the poking the paperclip the the programmer's hole ( we won't go there) Nothing. This machine has 160 gig of ram and no firewire. It tells me the hardware is up to date and it ran 10.35 no problem. (What is the max ram I can put in this machine?) Any ideas???
