Mac app store needs my apple id?
I have recently switched computers and have given my old macbook to a family member. I deleted my home folder and account and they made their own. However I left all of my apps on the mac. and now when they try to update them, they need my apple id? How do I fix this so that they can use their own instead of mine?
MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)
