App Store won't let me download updates
Per App Store, I have updates ready for: iMovie, iPhoto, Keynote, Numbers and Pages. When I try to log in so I can download, it never logs me in, just gives me the spinning gray wheel FOREVER. And won't let me click Cancel or click away, I eventually have to force App Store to quit. (And before you ask, I HAVE verified that I'm entering the correct ID and password, so that is not the problem. I recently upgraded the OS to El Capitan. Other updates were available and I was able to download them today: an El Capitan update, iTunes update, and Camera Raw compatibility update. Those worked fine. Can anybody out there help me? Thanks!!
iMac (27-inch Mid 2010), OS X El Capitan (10.11.1)
