How do I change the apple id to update apps from Appstore on mac

if you put the final helpful answer as the last post instead of explaining what you did, that would be more helpful. Anyway, have to keep two accounts is not a reasonable design. it should be bind with the machine instead of an user account.

The Mac App Store and the iTunes Store work identically and the two store function as those who owned the original content that was sold by the iTunes Store, which came years before the Mac App Store, music and videos (music, movies and television programs) required Apple to sell their product, that the user licensing for the content is to the person, not an inanimate object, the Mac or iOS device. That's why the person's Apple ID is encoded in the copy that they download. Which is why the Apple ID that bought the content is the only one that can redownload or update the content, not whomever may be using the device.

I see, thanks,

but I don't think I bought iphoto and imovie, it came with the original new machine when I bought it. but when i changed to use another account. I have to keep both of them. but I have several apple products.

Will refuse to buy any apple product again. It looks not a reasonable design to me. So, never an apple product again, including the coming iphone 6 which i like most. But the software is unacceptable!

FYI. Just remove the app from your computer and re-download it with the new apple ID. worked great!

This is the most helpful answer to the question about the iphoto and the imovie update. Follow up question, did you lose all of your iphoto pics when you trashed the app?

The photos are not stored in the app bundle. Your photos are in the iPhoto library located in Users/~/Pictures

~ = username

Thanks for the reply. Let me ask the question a different way. If i trash my iphoto app, am i going to lose all my photos?

No.

Thanks! Stay tuned for more brain-buster questions when i finish the new iphoto upload.

This answer worked like a charm and was exactly what I needed. I inherited a machine that had previously been tied to another Apple ID, but no longer.

you've created a lot of necessary confusion

Yup, my thoughts exactly. I did the trash bin technique; removed all the apps that were tied to old apple id and reinstalled the ones I cared about. It worked and i have free'd up valuable MB of disk of apps I never used. Bonus.

I'm having the same issue with Pages. New Mac bought last week. Pages needs to be updated. For whatever reason (I have no idea why), it wants to update using my daughter's ID. (The machine was set up under my own ID.) I read here and after going through the ridiculously arrogant "tough luck that's the way it is, if you don't like it you shouldn't be using Apple" type answers (who ARE these people?), I came to the workaround solution of trashing the app and reinstalling. Except... it now wants me to pay $25 for an app that came included with the machine. Any suggestions?

You set up the Mac with your Apple ID, does your daughter also have a user account on the Mac? The app is asking for her Apple ID because it and likely the other 5 apps that came with the Mac, iLife and iWork, have been associated with her Apple ID. Meaning that her Apple ID is encoded in the app's bundle. When the Mac is new, you need to open the Mac App Store (MAS), sign into your MAS user account (Store menu), go to the Purchases pane and Accept the 6 apps presented there into your user account. It appears that your daughter did that. There is no easy way to undo that. And in the end, the MAS likely isn't going to sell you those apps, even if it looks like it wants to do so.

Hmmm. She's certain she hasn't been into the MAS and done what you suggested. She does have her own Apple ID and she was the first user to use Pages, so was the active Apple ID when it goes through the "let's get started" bit. I don't recall any prompt asking me to do anything in the MAS when I first set the thing up - all the apps were just there out of the box and people started using them (and it's no surprise that the kids beat me to it!).

Looking at Keynote, which she was also the first to use, I can see the same thing has happened. What are the other apps you talk about? I'll see if there are any others which she hasn't used and whether the problem exists with them.

I have to agree with other users, although I love most aspects of the Mac, this is pretty crappy.

In the end I have reinstalled Pages under her ID for free, which it was happy to do, and from what you're saying there appears to be nothing else I can do about it. Yuck.
