It's hard to believe that both of these super giants in the O/S industry would have released a product that broke numerous packages out there. Of course any manufacturer including M/$, and their ill fated Windows 10 recently released, have suffered fielding numerous support calls saying 'Why Won t This Work?, Why Won't that work?' Me, like many other MAC users updated their MACs to the latest greatest thinking that Apple would have fully beta tested before it's release. I loved Andy! currently still waiting for an update so it will work on El Capitan.
