Hello Mrvs106,
Welcome to the Apple Support Communities. I understand there are some concerns with the screen and Touch Bar flashing colors. I'll do what I can to help.
If there are any other adverse effects, try resetting both the PRAM and SMC that controls both the display and Touch Bar:
If you're still seeing the same thing after the resets, answering these can help clear things up:
Enjoy.
Mrvs106,
Thanks for the additional details. If you haven't already, go ahead and proceed with the resets of PRAM and SMC.
If it still happens, try starting the Mac in safe mode and shutting down from there to see if the same thing happens: Use safe mode to isolate issues with your Mac
Take care.
Hi Jerrm_v
thanks for the reply, nothing happens during shutting down and it does not occur when I'm starting up. One day out of the blue when I shut it down before the screen turns black there is a very quick streak of colours would flash before the screen shuts off.
With regards to my touch bar it does it ones (the time I decided to message here in the community) but the unusual colour in the screen still prompt.
thanks will look into it once I perform the SMC and Pram reset
screen and touch bar
