OS X 10.11.4 MBP 13" 2015 By default it is not possible to rotate the internal screen. But when you hold the "secret" shortcut CMD+ALT before you choose "Displays" in the system preferences, you get the option to rotate. But: After that action you get a black screen. You have to reboot. Than the screen is rotated. You get another resolution: 1600x2560. You can't change it. For my eyes that resolution is to small. Questions: Is there any workaround to rotate the internal display without the show stopping effects I described above? The best would be, when the display would rotate automatically by detection of a position sensor. Thanks for your help.
