Green screen immediately after opening my 2017 15 inch MacBook Pro with Touch Bar Lately, I've noticed that any time I open my 2017 MacBook Pro after at least an hour of not being in use, there's a flash of light green that fills the screen before the log-in screen appears. It's only for about a half second, but it bothers me because I just got this computer in December, and I want to make sure nothing is wrong with it. I'm not sure what would cause this to happen, so I was just wondering if anyone else has/had this problem and knows what it is and how to fix it?Thanks

My macbook pro retina (early 2015) stays on a grey screen after waking up from sleep mode Hello,My macbook pro retina (early 2015) is not waking up properly after sleep mode. When I open it to wake it up after sleep mode, the screen is grey, but I hear sounds from emails coming in etc... So it's a screen-problem in my opinion. The only way to make it work again, is tot do a hard shut down by holding the on/off button a few seconds and than start it up. After starting up, the macbook works normally.So the problem only occurs after sleep mode.Has anyone else had this issue? How can I fix it? Is it a hardware problem?Isabelle

Try an NVRAM reset:

even if macjack's "approved method" does not work for you, I doubt this problem is caused by any hardware flaw.

The graphics subsystem has been completely revised in High Sierra. If the problem clears itself in a second or two, this is likely to simply be programmer's oversight.
