wrong Apple ID to download updates from the App Store
I just installed Yosemite and I am trying to update apps. When I click on an updatel, I get a box saying "Sign in to download from the App Store". However, it shows my son's Apple ID and I can't click in the box to change it. I'm logged into ICloud with my ID and the App Store shows my account. It just shows up as my son's ID when I try to download an update.
