Q: itunes says there's an update but doesn't appear in app store

Thanks for the question. That definitely sounds weird and frustrating! Let’s see if we can resolve this issue. To begin, try out the steps in the following resource:

 

Mac App Store: Cannot update App Store purchases or updates do not seem available - Apple Support

http://support.apple.com/en-us/HT203604

My startup volume was not listed on the Privacy tab in Spotlight.

Troubleshooting the Mac App Store - Apple Support

Sorry, but that link was useless.  None of the suggestions in that link are valid. 

If an app purchased on one Mac does not open after being copied to another Mac

I did not "copy" iTunes from one Mac to another.

If you are unable to find an app you purchased from the App Store

I didn't buy iTunes in the app store, it was pre-installed on my MBP just like everyone else's.  And I don't have a problem finding iTunes, i use it all the time.

If the Mac App Store application was removed after installing the Mac OS X v10.6.6 Combo Software Update

Don't even have a clue what this refers to.  I am running MAC OS X v10.10.2.

If nothing happens after clicking Buy when purchasing an app

This is irrelevant.  Again, I did not purchase it from the App Store.

If downloading an app is interrupted

Again, irrelevant, i have not even downloaded it yet and none of the versions i ever downloaded have ever been interrupted.

And this one?  Where in the world did you come up with this one?  I do not use boot camp and do not have NTFS files that are causing this....

Sorry, but that was the MOST unhelpful post I have ever received here in the communities.....

Just because your info wasn't helpful doesn't mean nobody else's on here would be.  I have gotten plenty of help from other users in the communities and didn't have to PAY APPLE for support for their products.

Not to mention the fact that it is not a huge issue, it was more of a curiosity than anything else, all the more reason I will not pay Apple to figure it out.  Your lame suggestions just set me off is all.... 

Furthermore, I am not trying to be ungrateful or anything like that, simply hoped for a better response than that.
