I bought a 2012 Mac mini secondhand and do not know the password to it. I have tried resetting in all the normal ways, but found there is no operating system on it. Turning on the unit brings up a screen with a flashing folder with a question mark on it.
Reatarting it while holding windows key + R only brings me to a screen to input a password, which I do not know/have.
I cannot find any other way via internet searches. Is there something I'm missing? HELP
