    G4 - Open Firmware commands
    I am trying to run Memtest off the command line from a USB drive. OSX will not boot so I'm forced to run it from open firmware. If anyone knows, I need the commands to mount the USB device, access it, mount the dmg, and finally run it. Any help at this point is greatly appreciated!!

    Specs:
    Late 2013 27" iMac, iPad 3, iPhone 6s+, iPhone 6+, 3 iPods, El Capitan
    Have you tried booting the machine with your original install media and run the memory test that way?

    Regards.
