A friend's macbook has no admin account, and that makes it a bit useless for obvious reasons.
We've done a lot of searching around, and haven't been able to get it running. The most popular method seems to be to boot into single user mode and delete
.AppleSetupDone, however holding down
S on boot only flashes a terminal for a moment before proceeding to boot normally - not enough to see what it says.
The other common method seems to be to use recovery mode and run the
resetpassword command. We can boot into recovery mode successfully, but the resetpassword command only brings up a blank white box.

tl;dr No admin account, can't boot to SUM and
resetpassword is useless.
