I have a brand new iMac running El Capitan OS (10.11) and updated all of my CC apps. Everything seems to be working fine except for Bridge. Bridge does not open up .ai files when you double click them. It will for .eps, but not .ai even when they are saved in the latest Illustrator. I did check in the finder to make sure that Adobe Illustrator CC 2015 is the default app to open them with. Something is wrong here. They open fine when I double click the file int he Finder window. The only way I can open these within Bridge is to drag it over the Illustrator icon in the dock.
