BabyDollNina,the problem is, that these applications are associated with the previous owner's AppleID and the right to use them cannot be transferred to a different AppleID, when you sell a Mac.

As Niel said, you have to download version of the apps, that are associated with your appleID, to be able to update them. And hurry to do that, do it today, iPhoto will soon no longer be available from the AppSore.

I am puzzled, that you cannot even update to MacOS X 10.10.2. Which version of iPhoto and MacOS X are you currently running?

What model of Mac do you have?

Deleting and redownloading iPhoto won't affect its library. Back it up anyway.

You delete the iPhoto application from the Applications folder.

And copy the iPhoto Library from your Pictures folder to an external drive.

To re-install iPhoto

1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)

2. Download it from the App Store to reinstall It's on your Purchases List* there.

*Sometimes iPhoto is not visible on the Purchases List. it may be hidden. See this article for details on how to unhide it.

One question often asked: Will I lose my Photos if I reinstall?

iPhoto the application and the iPhoto Library are two different parts of the iPhoto programme. So, reinstalling the app should not affect the Library. BUT you should always have a back up before doing this kind of work. Always.

Most Simple Back Up:

Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.

Slightly more complex: Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically.

Example of such apps: Chronosync- but there are many others. Search on MacUpdateor the App Store

has a lot of information for new users.

You update the OS via the Mac App Store.

1. Yes, but see #2.

2. If Mac OS X itself is tied to an Apple ID, the whole OS needs to be erased and reinstalled; to do this on a computer which shipped with Mac OS X 10.7 or newer, restart with the Option, Command, and R keys held down, use the Disk Utility to erase the main partition, and reload the OS. Back up all your data first; this process will erase everything on the volume, including Xcode and iMovie.

Your system would become more vulnerable to security threats and lose compatibility with new application versions over time. In addition, if a future issue requires a partial or full OS reinstallation to resolve, you’d need to log in with an Apple ID associated with Yosemite.
