This is an accurate restoration, as a recording of this being done on real hardware is available and they sound identical, except for the recording having distortion

Why does it beep before the boot chime?

I could've sworn my iMac woke me up doing a security update overnight

Why is the progress bar different than the other one?

I was trying do this on my mac pro and it did the same thing but I unplugged it and plugged it back in

Can I ask a question? -> Who cares? What do I learn from this video? (Ok, granted... That was two questions.)
