In Applications/Photoshop, right clicking or ctrl+click does not give me "Show Package Contents" (it does work for Lightroom 4) - I beleive it is necessary to get to Show Package Contents in ordder to add Photoshop to the dock? Or is there another way to add Photoshop to the dock?
Are you talking about Mac OS?
If so just start the application and then click the icon in the Dock until the pop-up menu appears and select Options > Keep in Dock.
Excellent, thank you!
