I had to combine steps from multiple guides to finally get the Mac to boot from the USB, and figured that I'd post a comprehensive guide here. I had followed many guides online but was never able to get the Mac to boot from the USB or install OS X. The iMac already came with OS X 10.5.8 installed but I wanted to do a clean install of the OS for security/performance purposes.
So this all started when I got an old iMac G5 iSight model from a computer recycling store. While this guide is targeted toward Mac OS X 10.5 Leopard, it still applies to other versions of Mac OS X, including any Server versions from 10.4-10.5, and possibly 10.0-10.3 as well (although I haven’t tested that). I figured I would revive this subreddit with a working guide on how to create an OS X Leopard bootable USB for PowerPC models and actually boot the computer from it, and provide some extra tips/software suggestions.
