    Is it possible to boot Mac OS X (iMac) from a USB thumb drive device?

    It is possible if you have one large enough. I think you can just about make it with a 2GB drive but I would say that is the minimum you could get away with.

    If the format on the thumb drive is fat 32 then it won't work.. Reformat the drive to HFS+ inside of disk utility..


    Then it should boot once you installed the OS and have enough space ...:eek:


    Hold down option/alt key during boot up to select boot drive...


    The said steps are for intel based Macs,since PPC Macs won't boot from usb ...

    the later ones do

    I remember installing OSX on my thumb drive when I first found out and I used an application that only install the necessary things as I only had a small drive at the time but for the life of me can't remember the name of it.
