I just got the iMac - latest version I7 with 16 gigs Ram. I simply want to open files from Bridge and do raw edits there before opening in photoshop. Creative Cloud - also just upgraded to that yesterday. Everytime I try opening a photo it launched iPhoto
I think I just need to steer clear of “iPhoto”
For files you see in Bridge:
Go to Bridge > Preferences > and from the Left Pane, choose File Type Associations
For your raw files, jpegs, and other graphics files, choose Adobe Photoshop in the right pane.
For importing Photos from your camera and sdcard:
File menu > Get Photos from Camera
It will ask if you want Bridge to do this in the future. Say "Yes" and check "Don't Ask Again"
Let me know how it goes.
In the Mac Finder
Cmd i > Open with > choose Photoshop Click on the Change All button
