Installing 10.5 on an old eMac

7 posts in this topic

Recommended Posts

I just bought an old eMac today w.


-700mghz g4

-512mb ram

-40 gig HD


-Running OSX 10.3


I'm trying to update the system to 10.5 and the problems are that 10.5 is on a DVD (so the CD drive isn't going to work). So I hooked up an external DVD drive w. usb. This doesn't seem to work, the system recognizes the disk and prompts me to restart to begin the re-install. But after the re-start it brings me back to the desktop and the install has not begun.


I've assumed that the problem is that I'm using a usb connected external drive. So I'm trying to install from a usb thumb drive. I do know that the 700mghz processor is technically not supported by 10.5 but this guide...




states that I can get around the issue. The only thing that I'm concerned about is if I can actually boot from the usb drive in the same way the above guide tells me to boot from the cd.


Any help would be apperciated.

I decided to take everyone's advice and go with a Tiger install instead. I downloaded a CD version of 10.4 which I burned to some CD's with another mac and I'm installing right now.

It's a little bit late, but I've found OS X to be a lot like Adobe--a RAM piggy. My 733 G4 with 1.5 GB of RAM runs Leopard nicely. If it runs sluggishly, try throwing more RAM into it.

Installing Leopard on an eMac? Sounds tricky. These things were discontinued long ago, so I don't think it'll run very smooth.
