I discovered some very peculiar behaviour with the 2017 MacBook Pro (15", touch bar model). When I booted into safe boot mode, I would get lots of non-Apple-like horizontal banding and flickering during the boot process and login screen. Then, if I went back to the login screen, the colours would be inverted. Upon logging in again, the screen would display in a bizarre sort of LSD trippy way. It defies description – see the attached pic. The actual desktop is a picture with orange-brown grass and lots of blue sky.
Okay, the two Apple reps that saw it told me it was a motherboard issue and so I got the MB replaced (they also replaced the "top case," which basically means I have a brand new computer aside from the display :-/ ).
I've got the new computer back, and out of curiosity, went through the steps to reproduce the problem. Turns out, replacing the motherboard didn't fix the issue, I am seeing the exact same visual glitches.
Does anyone out there have one of these machines? Can you reproduce this? I'm wondering if it's a built in design flaw or maybe I'm just really unlucky with AppleCare repairs (long story, but I have the current machine as a replacement for one of the ill-fated 2011 MacBooks with the graphics chip failure – four failed motherboards on that one and I was able to convince them that they owed me a new computer).
Again, the sequence is
• safe boot (start up with the shift key held down)
• log in to an account (are you seeing the flickering/banding?)
• go back to the login screen (are the colours inverted?)
• log in again (is the display tripping balls?)
I'd appreciate hearing from you either way (problems or no).
Thanks!
