Question: Macbook display settings unavailable
My macbook is setup with an external monitor. since recent update, if i lift lid and disconect my monitor cable, my screen doesn't come back on like it used to. if i plug it back in and use the external screen to check dispay settings, I am only seeing dispay setting for external monitor ONLY, not the macbook. Only a restart returns it to how it used to be, being able to view macbook display settings and also external monitor settings. I cant restart my computer every time i need to disconnect my macbook from its monitor???
MacBook Pro (13-inch Mid 2012), macOS Sierra (10.12.6)
