View Full Version : Booting Powerbook G4 via External FW 800

Jul 2, 2010, 09:35 PM
Hello all,

I am trying to do a clean install of OSX 10.5 on my old powerbook G4 15". I am using a 10.5 image file on my external. I partitioned the external using GUID, and restored the image file onto the external. (this method works when installing on intel macs). Unfortunately, I cannot boot 10.5 using this method on my powerbook. Is it because i am using a firewire 800 cable? Should I be booting it using a firewire 400? I know that PPC macs cannot boot using usb, so i am stumped. Please, any help would be greatly appreciated.

Thanks in advance,

I think the main problem is you're using GUID format on a PowerPC. You need to use the Apple Partition Map format. GUID is for Intel Macs.

Thanks, I'll give that a shot.
