Why won't my Mac recognize my screen as an internal monitor?
I recently replaced my cracked screen with a new one that I bought from amazon. The full screen, not just the LCD so it was a do-able repair. The display seems to work, BUT, there is no brightness adjustment available anymore. It doesn't show up under display preferences. No slider, and the Touch Bar adjustment doesn't do anything. It is as though it is treating the new internal screen as an external monitor.Screenshot2
