How to get rid of Updates from Other Users

You have a pirated app. That Apple ID usually appears when the user has installed a pirated app purchased in the App Store, so the only thing you can do is to remove this app

Note that Angry Birds is not installed in your Mac. The problem is that the person with the Apple ID had this update and everybody who downloaded her/his pirated app has got the update message.

You have to look for the pirated app. First, if you have any external drive plugged in, unplug them. Then, open a Finder window, go to Applications folder and look for any app that could be downloaded from the Internet. Another way would be to use Launchpad and hold the Option (Alt) key, so all the Mac App Store apps will show an X button. One of them is the pirated app. Also, look at Downloads

You installed a hacked app, originally from the Mac App Store. It contains the receipt for a different app, downloaded using an account that you don't control. You need to identify and remove the hacked app.

Important: The app you need to remove is not necessarily the one named in the App Store notice. For example, if the App Store says you need to update "Twitter," the hacked app may be "Angry Birds" or something else entirely. Don't make any assumptions about which app you're looking for. To find it, you have to carry out a systematic search.

Triple-click anywhere in the line of text below on this page to select it:

kMDItemAppStoreHasReceipt=1

Copy the selected text to the Clipboard (command-C).

In the Finder, press the key combination command-F to open a search window, or select

File ▹ Find

from the menu bar. In the search window, select

Search: This Mac

from the row of tokens below the toolbar. Below that is a popup menu initially showing Kind. From that menu, select Other...

A sheet will drop down. In that sheet, select Raw Query and click OK or press return.

Now there will be a text box to the right of popup menu. Click in that box and paste (command-V).

The search window will show all the App Store products you've installed. Compare those search results with the list of your purchases from the App Store. To see the complete list, you may need to unhide hidden purchases. If any apps were download from the App Store using other Apple ID accounts that you control, sign in to the store under each of those ID's and check the purchases.

At least one of the items listed in the search window is not among your purchases in the App Store. Move each such item to the Trash. You may be prompted for your administrator password. Empty the Trash.

Log out and log back in. Test.
