how do i reset my apple id on my iMac?
My Apple ID is associated with a lot of things on my iMac. I recently changed my Apple ID and haven't changed it on my iMac. But when my iMac needs my Apple ID, it automatically pulls up my old Apple ID. How do I change this on my iMac (not the internet). I need to change it inside my settings or something so that my new Apple ID comes up when I need to authorize something on my iMac.
