Please check if Camera detecting is fine in Finder and also update the latest camera raw plugin for bridge.
Download Link: Camera Raw plug-in installer
If you have any camera software which came with canon see if that works for Import.
Let us know if it helps.
Hi mohgoyal and thanks for your help,
I have the same problem with my Nikon D3000.
I've just tried to update Camera Raw but it doesn't work.
Maybe the new Apple Photos application "stop" something during the connection?
