I have a 2011 iMac that was of course working just fine. I got an alert it had been locked with my iCloud so powered up, and on the screen it says disabled try again in 60 minutes and has a fake email at the bottom to email if I can't get the iCloud unlock password. According to Apple, my iMac is not in fact locked by iCloud so I can only assume this is a fake screen especially since it's got a fake email at the bottom and no place for me to actually enter the password. I tried resetting SMC/NVRAM and this enables a firmware lock screen which I've never setup I can pull the RAM and remove it and it goes back to the faux iCloud screen but any action I take results in the Firmware lock screen. Can't boot into recovery, can't select startup disk to remote reset with Target Disk from another Mac can't start in Single User mode- NOTHING WORKS! PLEASE HELP!!! Apple won't help because I can't get proof of purchase from Best Buy since it's more than 5 years old.
