Hi, I've been lurking the forums for some time, but I never registered until now. Prepare for this cause it's quite a problem, here goes: I have two iMacs, the intel iMac (Early 2006) and the PPC iMac G4 (USB 2.0) [last generation of the moveable flat-panel iMacs], and I wanted to install Mac OS X 10.5 Leopard on the G4. Now, my G4 is capable enough for Leopard, it has a 60GB HD, 768MB of RAM (required minimum is 512MB) and 1GHz processor (required minimum is 867MHz). My problem is that the Leopard DVD is a dual layer DVD, and the G4's drive can't read DVD DL. So I can't install Leopard the old fashion way. I tried putting the G4 on Target Disk Mode and install Leopard from my intel iMac, but the installer says that because the G4's drive doesn't have a GUID Partition Table (which is exclusive to intel iMacs), it can't install it on the G4. So I tried it backwards, put the intel iMac on Target Disk Mode with the Leopard DVD inside and boot into it from the G4. Putting it that way enables me to see the disk as normal and boot into it until I get to a blue screen and the computer just hangs there with the colored spinning ball on the screen, while the intel iMac makes a lot of noise reading the Leopard DVD. I waited for about 15-20 minutes and nothing happened, it just hangs. I really want to install Leopard on my G4, but I can't think of any other way to do it. Any help is greatly appreciated.
