So..........my mid 2013 13" MacBook Air seems to have gone to the great beyond. Its the base model; Core 15, 128g, 4 g ram. I went to boot it up and it gave me a message saying it had encountered an exception, then proceeded to get stuck on the recovery screen. Its been stuck that way ever since. It won't shut down either. I've tried to hold the power button down to no avail. I've also tried any and all diagnostic and repair keyboard shortcuts available that I know of. The only thing that works is the pointer. The track pad is picking up my movements and moving the mouse accordingly, but that's about all that's worked. Now that the battery is dead, I'm going to try and pull the cable, but I'm not sure a MacBook will boot up without the battery plugged in. Anyone have any ideas that don't involve finishing it off with fire? I'm just not sure how I can troubleshoot a completely unresponsive machine. I was thinking of making a bootable image on a flash drive and reinstalling the OS, but if it hangs on recovery I don't see how that's possible. Thanks in advance for any and all advice.
