I have a Macbook which is setup with an external display. At the moment the external display is set to "the primary" screen and the Macbook the second.
I know in order to change the Macbook screen to the "primary" screen i have to go to System Preferences >> Displays >> Arrangements. But is there a way of automating the process so i can easily switch between the two (say with a icon in the dock). I have had a look through Automator, but nothing seems to fit the bill.
Anyone?
