I’ve got an issue with the Touch Bar that, as far as I can tell, only I am experiencing:
Take your MacBook Pro, put it in a room indoors, and flick the lights on and off in that room several times a second. You’ll notice high CPU usage on a process called “TouchBarServer”, as it tries to adjust itself to the changing light levels so it can display its screen. For some reason, as it does this, it lags the entire rest of the computer: scrolling will freeze every couple of seconds, clicks won’t register, the mouse will lag, and keystrokes will just be ignored.
Why would you do this, you might ask? I work on trains a lot, and I get this same flicker effect as the trees by the tracks go past. As they pass the windows of the train, it’s like a bright light source is being rapidly turned on and off.
I don’t ever use the Touch Bar — nor did I want one — but merely having one renders my laptop unusably slow for two hours every day. I hate this computer.
