Can Malware/Virus Lock Set a Firmware Password
I think I already know the answer to this questions, however I’ve been given a 2017 iMac with a Firmware Password set won't boot up at all (just showing the Firmware Password Lock). The previous owner is convinced that they have been “Hacked” and the Malware has Set the Password. As far as I’m aware, you can’t set the Firmware Password from within the OS. I’d could see a drive Encryption happening but not a Firmware Utility Password.
However the Mac won’t boot up, so it’s starting to puzzle me. As Firmware Passwords wouldn’t lock the Boot Drive, would they?
Any help would be greatly appreciated. I’m thinking of just swapping the EFI chip, would this work?
