Hi, I have a 2017 MacBook Pro with Touch Bar, and all of a sudden I noticed a black dot on my screen. I through it was dirt, so I cleaned the screen, but it still remains. So I through it might be a scratched, so I shown a light on it and I couldn't see a scratch. I'm thinking its a dead pixel?? Its really small and hard to see, but I'm OCD and this is driving me nuts!
