This is the one thing i hate about Apple, if stuff doesn't work they want you to bring your computer to them... a pc i could just wipe out the drive and start fresh... Is there a way to do this on MAC? Please read on to see why i want to do this... I have had no luck, and my mac is running very poorly! I am trying to install the tiger i purchased.. it is the upgrade DVD. I am furious cause Apple can't help me after i spent money on the stupid program, and they won't take it back cause it is opened. Anyway here is my problem... I have a G4 dual 1.0 I try to install it with the computer on... when it directs me to restart i do and then nothing, it boots to the grey apple screen, but no gears start moving...the same thing happens when i boot from the disc! So i was gonna do a disc repair from disc, an old disc, but I don't have my original boot disc from my last upgrade to 10.3.9, but i do have 10.3.7 from my macmini, but that isn't working either... is there any way to wipe out and start from scratch, anything i can do? I want to do a nice fresh clean install... Please Help me. Thanks, i am goin nuts!
