Q: I always tried to back up my data on my storage drive with Time Machine, and was always shown the message "Could not back up disk do to unexpected error (-43)" After some research on Apple.com , I found that it was because my computer name contained punctuation. I have tried everything I can think of but can't find a way to change it. Does anybody know how I can change it without completely reseting my computer?
A: Its under system preferences=>sharing.
