I had originally experimented with the Mac App Store on my desktop computer installing a number of free and paid for applications. Now, I’ve finally gotten around to trying to install the same applications onto my MacBook Air just to see if I could, but I already know that I can. The licensing model of the Mac App Store allows it.
Unfortunately tonight the Mac App Store isn’t working and according to AppleCare there are two suggested ways to work around this that you need to try when the Mac App Store gives you an ambiguous error message: @@errorNum@@.
If you experience this error number then you have two options according to AppleCare:
Sign Out then Back into the Mac App Store
First, try logging out of the Mac App Store by going to the Store menu inside the Mac App Store application and selecting Sign Out. Next go back to the Store menu and select Sign In. Afterwards I tried to install an application from my list of purchases, but I still wasn’t able too.
Yes, I said wait. Try again later. If the above isn’t working then the Mac App Store is having database problems according to AppleCare. The only thing you can do is wait it out. Unfortunately there is no way to check the stores status, etc. I hope Apple will resolve that at some point and offer something to provide that information.
I left this post idle in draft mode for about an hour and tried the Mac App Store again. This time instead of the error I got above I was asked to verify my credit card information because I hadn’t used it on my MacBook Air before. I entered the required information and I was quickly downloading and installing my apps once again.
