Q: Angry Birds update, but not owned?

You have a pirated app that you downloaded for free from somewhere on the internet. The pirated app has been cracked by the pirates with the MAS receipt from the Angry Birds app acquired with this other persons Apple ID. Get rid of your pirated apps and you will get rid of this problem.

Read what I actually wrote. I said that the pirated app that you have gotten somewhere for free has been cracked with the MAS receipt from Angry Birds acquired by this other person's Apple ID. The MAS is reading the receipt and notifying that Angry Birds has an update.

Finding a pirated app

All MAS apps have a MAS receipt in their app bundle. Check any app acquired from the MAS. Right click on the app's icon in your Apps folder and choose Show package contents. In the Contents folder is a _MASReceipt folder and in that folder is the coded MAS receipt. It has the Apple ID of the MAS account that bought/acquired the app from the MAS. It is that receipt that the MAS uses to alert you that an app has an update. There would not be a notice of an update with someone else's Apple ID showing in the MAS on your Mac, if there was not an app with a receipt from this person's account somewhere on your Mac.

Download the free app FindAnyFile (FAF);

This app is easier to use and seems to be more powerful than Spotlight. Open FAF and in the box type _MASReceipt and press Find. It should come up with a list of every app on the Mac with a MAS receipt. Compare the apps with receipts in FAF's list with your purchased apps list in the Mac App Store. The odd app out should be the pirated app.

Then I suggest that you look outside of the ASC for a solution. No one here will be able to assist you with this issue because you still have no clue what I have tried to explain to you twice in simple English.

I have the similar problem. never purchsed angry birds for any device - but app store on my MAC (not itunes) is telling me to download an update to angry birds.

If I do have a pirated app, where would I find it?  looked in itunes - nothing, used spotlight - nothing..

I explained how in my second comment.

Can't you read? He is telling you that ANY PIRATED APPS you have downloaded are doing this to your App Store. By saying ANY PIRATED APPS, I mean that it doesn't have to be Angry Birds, it can be anything you pirated. Delete those pirated apps and you are good.

I have the same problem. I never downloaded angry birds, except the free version for my iphone. On my app store updates its there. I do not have any 'hacked' programs. no one seems to avbe to fix this from what i am reading online. IF anyone ahs clue on where to find the reason the update is in my app store, please post.

@dahveed I installed appzapper and entered a serial i had found on the web, which worked. This was when I had just purchased my mac. This problem came about this morning. I deleted the app and all its files up untill the point where i redowloaded it and i had to put a new serial and everything but still. That is the only app which i deleted and the problem remains.

You are looking for an app that you added to your Mac just in the last few months. You added it after the MAS was released with the 10.6.6 update. It is an app that you got free somewhere, that is also sold in the MAS.

I JUST got my mac last week. Only installed appzapper and then deleted it and all its files

Did you have another Mac before this ne one? Did you migrate anything to the new one?

All you say in your first comment here is that the problem remains. Explain to us clearly what problem it is that you are actuallu having.
