When trying to use software update, get error NSURLErrorDomain error -1100
I don't know if this is a result of anything I did. It started happening after I installed the latest version of Garageband. When I went into that app, and selected one of the instruments, it directed me to use software update to get all the data for the instruments. That's when I first got the message box. Later, I uninstalled Garageband, and still the update problem continues. Obviously, when this problem first occurs, it will have been after installing *some* app, so I have no way of knowing whether Garageband is involved. I don't think I can update any of my applications until this problem is fixed.
The full text of the message box:
An error has occurred
The operation couldn't be completed.
(NSURLErrorDomain error -1100.)
