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

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.

Bother.  She's been the first to use all of the Essentials apps, except GarageBand.  And GarageBand doesn't have an update available so I can't see if the same problem exists.

Looks like she's going to be Updater-in-Chief!

iLife = iPhoto, iMovie & Garageband

iWork = Pages, Numbers & Keynote

Any other apps that came on the Mac are part of OS X's installation.

For all people reading through the thread, ChewnaccaFreak got it right: HIS IS THE ANSWER TO THE QUESTION!

Just delete any apps installed under the old Apple ID (Finder > Applications > Move to Trash) and reinstall with the new Apple ID.

Hi there,

Have read through all of the posts and have cured the iPhoto issue by deleting and re-installing using my Apple ID. However, I am the only person to use my Mac Mini (for personal reasons - I won't go in to) I bought my Mac Mini in 2010 and am only just able to use it now.

When I deleted and re-installed iMovie '11 v9 from the original DVD it told me that my certificate had expired. However, as I have only ever used it myself from new, I cannot understand why it won't update.

Can anyone explain, or tell me what to do about it ?

Many thanks

TK 

PS - Is there any way of finding out which Apple ID is associated with the app(s) I cannot update (in this case iMovie) ??

At least then I may have an idea what's gone wrong ?

Cheers

If it's the same problem / "feature" I have (and will have forever more apparently), I could see the associated ID when I went into the App Store and attempted to update the App in question.  I was prompted for an Apple ID and password to proceed, but the Apple ID was already set to be the associated ID, with no ability to change.  Doesn't work if the app doesn't need updating though.
