Hey all, I have an imac g4.

I would like to install mac osx leopard.


iMac G4 700 15"

Processor: G4 - 700 MHz Geheugen: 640 MB Harddisk: 40 GB



Can I restore the dmg to a separate 10 GB partition and then boot from the alt option?

Good morning, 

I recovered my old and wonderful macmini where I installed the image file of Leopard 10.5.6 patched to support my version as with less then 800mhz but I don't know the reason it start only in Safe mode. 

My version is equipped with the radeon graphic card and how can I know with xkext is making issue? 

There is a way to boot the machine only with the standard set of Leopard extension? I ran also the or update and after that my ppc didn't start anymore.

As I think from the specification mentioned above, you have a a low-end model of iMac G4. You can boot from an external BluRay player to install OS X 10.5. Firstly, boot into OpenFirmware. Now boot PPC by pressing Apple button and options key together.

Type: dev / ls


once you see the USB references then go ahead by giving the path of external drive and install OS X.
