The new Mac App Store was launched today, but a minor glitch still crept in. If you’re among the users repeatedly seeing the message, “We could not complete your App Store request. An unknown error occurred (100)” every time you try to download an app, try the method below.









Fix “Error 100″ In The Mac App Store [How To] :

1) Download any app in the App Store via iTunes, or one of your Apple devices with access to the App Store.

2) This will trigger the new iTunes Terms and Conditions to appear. They are failing to pop up for some users when they try to download an app in the Mac App Store.

3) Restart your computer and reopen the Mac App Store.

You should be able to download apps in the Mac App Store immediately afterwards.
