Hello EmilyM11,

Is it possible that you just updated your MacBook Pro to the latest operating system, which is OS X 10.10.2 (Yosemite). If you click on the Apple logo in the top left corner of your screen, and then click About This Mac, what version is showing?

What is an Apple ID?

An Apple ID is a user name you use for everything you do with Apple. Creating an account for an Apple service, such as the iTunes Store or the App Store, creates an Apple ID. Apple ID allows you to access other Apple services. You don't have to create a new account for each service—just use your Apple ID.

For a complete list of all of the places you can use an Apple ID, see Where do I use an Apple ID.

I have multiple Apple IDs. Is there a way for me to merge them into a single Apple ID?

Apple IDs cannot be merged. You should use your preferred Apple ID from now on, but you can still access your purchased items such as music, movies, or software using your other Apple IDs.

If you are wondering how using multiple Apple IDs relate to iCloud, see Apple IDs and iCloud.

I have purchased music, apps, or books with multiple Apple IDs. How can I get all of this content onto my iOS device?

First, copy all of your purchased content so that it's on the same Mac or PC with iTunes. This computer should be the one you sync your device with.

Next, authorize your computer to play content with each Apple ID in iTunes. After your computer is authorized for all of your content, it can be synced to your iPhone, iPad, or iPod touch.

I hope this information helps ....
