Yup ! Though I get another glitch where it shows my current screen and the login screen back and forth every second, I can't actually use the MacBook when it gets like this.
Its made worse with this combination of factors :
- I will leave my new MacBook in clamshell mode (closed) plugged into the monitor over night. Not an unlikely scenario by any stretch of the imagination
- The next morning, or after say 5 hours, I will hit my Apple Bluetooth External Keyboard (the new one) to wake it up. The monitor won't wake up. OR it will wake up but the part where you type in the password will not show. I will then open the MacBook from clamshell mode. It also won't have any place to type in the password.
- So now I can not use the Macbook at all at this point. I disconnect the MacBook from the external monitor as my only recourse.
- Either it works - type in password, reconnect the monitor, start using it. Or it starts displaying graphic issues like the video you attached, make it unusable. Then I have to force shut it down or restart it.
This is with 10.12.3. It is a *slight* improvement over 10.12.2, where the MacBook would simply be in a hard crash state. Nothing would wake it up and I've had to force shut it down - a fantastic feeling for a brand new product.
So given the combination of issues, I have to always remember to disconnect the MacBook if I think I'll be away from it for a few hours, and at the same then hope the graphic glitch doesn't mess it up anyways. Or don't use the external monitor at all, which sucks.
