I am in desperate need or some advice I'm how to unlock my MacBook Air model A1466 . I bought the computer used and shortly thereafter I shipped out with my Peace Core unit. I made the mistake of letting my nephew use the computer and evidently had absolutely no idea what you was doing and from what I have read he remotely locked my computer and does not remember any of the information to unlock it. I have no idea what my Apple ID is for the password for that matter. I was stupid not to write it down but I only have the computer for couple weeks before I left the states. if any one could be kind enough to give me some advice or suggestions on how to troubleshoot this it would be greatly appreciated. unfortunately my warranty is no longer valid and I am NOT about ready to dump hundreds of dollars into tech support. against any and all suggestions would be greatly appreciated thank you
