If you’re like most people, you use your Apple ID to sign in to your Mac, access iCloud, and shop on the App Store. But what if you want to change your Apple ID? Here’s how to do it.

Finally, make sure that “Remember my login information” is checked so that next time you sign in using your new information, everything will be automatic! ..
