Changing Registered Apple Id on Mac Book
Hello,
Recently i brought a Mac Book Pro (Late 2012). And I registered it with my current Apple Id that I created when I brought an iPhone years ago.
Yesterday I joined to the Developer Program with a new Apple Id. And I want to change the registred Apple Id on my Mac Book and iPhone with the new one. But I do not know how. And am I be able to update apps come with the Mac Book Pro in the future with my new Apple Id?
MacBook Pro, OS X Mavericks (10.9.2)
