Easily boot from USB 2.0 drives on PowerPC Macs
Authored by: hamishb on Oct 24, '06 10:12:24PM

Could this be used to boot from a Flash Drive? Thinking of adding a couple of gig to my Mac mini webserver in order to "save" the hard drive.

One problem with booting OS X from a flash drive, is all the write operations that take place on the boot volume while OS X is running (including virtual memory swapfiles) might eventually cause the memory locations on the flash drive to reach their maximum rated number of write operations after a shorter time than a hard drive's disk sectors.

But in specific, late answer to the question, yes, most flash drives (bootable ones--some early ones aren't bootable, and some early (and maybe some later?) USB drives aren't bootable) will boot OS 10.4.3 and later, from USB (1.1 and 2.0), on most Macs, starting with the slot-loading iMacs, the AGP/Sawtooth G4, and the Powerbook G3 Firewire. Some late-model Powerbook G4s don't seem to be able to boot from USB, but I haven't tested that much, to see if something else was going on that might be resolvable.
