  1. I'm starting a job as service technician and I'm using ASD to test our macs by pressing the But I don't know how an ASD EFI test is done, what key combination? ALT key, we have a server for that. I sometimes do a hardware diagnostic (pressing D or alt+D). Is it simply another way to call the ASD or MRI test? Do you need a usb flash drive for that?

    Also: what's an ASD OS, how do you do these tests?

    Thank you
