I had an altogether novel problem with my macbook today. I wanted to switch between Spaces (virtual desktops). While I hit the ctrl-up and ctrl-down key combinations a few times (perhaps I was indecisive, or maybe I had alien hand syndrome–I can’t quite remember what I did or why). That’s when the problem started:
The computer is switching back and forth between two spaces repeatedly. Despite some flailing at the keyboard, it lasted long enough for me to get my camera from the office. I then hit the power button to restart the computer. It sorta worked:
The quality of that video is probably too poor to tell, but that’s the shutdown dialogue that appears, then gets moved around with everything else. After aiming carefully, I hit sleep. When I woke up the computer, the problem continued, but this time I restarted, which thankfully gave me my computer back. I’ve not figured out how to recreate the problem.
