I have an Apple ID, I'm logged in now with it to the ASCs via this computer (MacBook Pro 15" running OS X 10.11; 2.6 GHz, 4 GB). I can use it to login to iBooks and the App Store on other machines (Mac Pro running OS X 10.10; iPhone 5 running iOS 9; miniMacs running OS X 10.10 etc), I can use it to login to my account in System Preferences -->> iCloud on *this* machine (MBP). But I cannot login to the iBooks store from this computer, I cannot login to the App Store from this computer, I cannot login to the iTunes Store from this computer.
Any ideas/suggestions, please?
