Q: new macbook air suddenly efi locked after connecting to internet
Bought a macbook air so i could run the programs i have on a bootable backup of my old macbook pro. Worked fine but when i finished ny project i signed onto the internet to send it off and walked away from the computer for a second. ...im not sure what happened... But when i came back in the room it was stuck on some weird screen and when i tried to boot it back up from my drive the EFI lock screen appeared.
So my question is, could the lock for the internal hard drive have kicked in if i was using an external drive to go online? Or could it be the lock set for my old laptop that caused it to trigger since this drive was a copy of the one i lost? I have used the drive quite a bit since then so i dont know why it would suddenly do that but i dont think i was using this partition of the drive b wecause i prefer the partition with an older version of mac osx which for some reason wouldnt work to boot this laptop. How do i fix it?
