Error message "This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled."Haven't bought anything but just downloaded El Capitan.

I have El Capitan, and am attempting to update iPhoto.

have not purchased a second-hand laptop and have not changed the language settings.

I followed your suggestions for clicking the "Reset button". This did not correct the problem.

Here is the dialogue:

1. I pressed reset button

2. I then attempted to update

3. -> request for re-entering App Store password appears

4. I entered my password

5. the password was accepted

6. The same old message appeared: “This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled”.

7. Immediately thereafter, a second message appeared: “There was an error in the App Store. Please try again later. (null)”

Please test after each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes. Keep in mind that no one here represents Apple or can help with customer-service issues.

Step 1

A purchased app can only be updated by signing in to the App Store with the same Apple ID that was originally used to buy it. There's no way around that limitation, which also applies to free apps. If you can't sign in with the buyer's ID, delete the app and reinstall it. You'll have to pay for it again, if applicable.

Step 2

If you get the alert when trying to update a bundled iLife app, select the Purchases page in the App Store and locate the app in your purchase history. If there's a button marked ACCEPT on the right, click it.

If you have a used Mac, the bundled apps were linked to the original owner's Apple ID and can't be transferred to you. Reportedly, customer service has issued redemption codes to some second owners who asked, but it's not guaranteed.

Step 3

If you're trying to update iLife or iWork apps that were installed from a purchased DVD, or if you have a refurbished Mac bought directly from Apple, contact App Store customer service for a redemption code. You may be asked for the part number of the DVD.

Step 4

From the App Store menu bar, select

Store ▹ View My Account

Enter your Apple ID password at the prompt. At the lower right corner of the window that opens, click the Reset button. Close the window.

Step 5

According to a report, the error can result from changing the language setting of your Apple ID account. I can't confirm.

How can I find out which app is causing this?

Thanks!

I realized after staring at the screen stupidly that after a later version of Yosemite, iPhoto was replaced by the Photos App. After deleting iPhoto now the App Store no longer bugs me about the update.

Thanks so much...i had this issue on my work Mac and it was annoying. I went to Finder > Applications > iPhoto and right click "Move to Trash". I entered my login for the Mac and it was gone from the AppStore updates list too.

Thanks a lot!!! After much reading just had to delete the iPhoto app and reset the appstore 🙂
