Mac OS 10.13.4 wake up screen glitch

I've been noticing this issue lately and Ive called apple support about it and we have tried clearing the nv ram and the cmos and it still will not go away. I was worried that it could have been a hardware issue but after doing some researching I think this may be a software issue with metal 2. every time I wake my MacBook Pro from sleep I get a brief 1 second flash this is what it looks like

I found a reddit post with a lot of people having the same issue and I hope that apple sees this and fixes it.


is anyone else having this issue on the latest version of high Sierra ? are there any fixes ?

MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13.4)

I have the same exact issue, bought my 13' 256GB pro in January of this year, 2018. Went into the Walnutcreek, CA store and they couldn't give me an answer, changed something in my settings and it still persists, they suggested that we might need to reinstall the software but after reading all these responses, I'm assuming that wouldn't work either....but here's an image of mine.

Yes, I have a similar problem. It happens with the touch bar. When the computer goes into sleep mode (screen turns off), after a few seconds, the touch bar flashes (extremely bright) similar to a freaky power surge. All i can hope for is this issue doesn't increase and effect the performance of my computer considering its less than a year old and I paid a freakin' TON of money for this thing😠

I'm so glad that I found this thread. I'm experiencing the same issue and I thought this could be my fault. The same wake up screen glitch and the flickering while watching videos (only when I use Safari). But since yesterday I'm on Mojave and I've got a new problem: today some black lines appeared on the bottom of my display. I just turned it off to eat something in the kitchen and when I came back and opened the Macbook they appeared. I tried everything (restarting, reseting NVRAM and SMC), but they still there. I'm really worried! Has anyone experienced this?

A heat issue is highly unlikely since my 2012 13" MacBook Pro usually only sleeps when the battery runs low, and upon plugging in and waking up, the aluminum body of the computer is actually remarkably cold until it has been in use for a while. I have attached screenshots of what my desktop looks like, including one with an open menu that cannot be read due to missing text. When this issue occurs, the only remedy is a full reboot, and to do so, I have to click on the Apple on the toolbar multiple times to see where "Restart..." is because the text will appear for just a second while the menu is trying to render.

Of all the threads I found online, this one here best describes the issues I'm having. Of all the descriptions of artifacts on the screen, the only one that looks exactly like mine are that of _shivairani_ and _rclarksworld_; namely the multi-colored bars and square pixely areas around windows, and menu bars. In that sense it is different from the original screen issues mentioned (with newer Macs). Interestingly, like those two users I have exact model , my computer is a 13" 2012 Macbook Pro (aluminum body). And here too, it happens once or twice a week upon waking from extended sleep, and if I reboot it goes back to normal.


This is happening on Mojave, and started at least since High Sierra (maybe even while on Sierra). The issue first manifested itself in a full screen of colored bars that would flash for half a second upon wakeup of the system, before showing the login screen with all things being normal thereafter. I was a little concerned about it, but didn't seek any solutions. It was around the same time that I installed Parallels, so I suspected that something about the virtual box software was messing with screen display issues. Any opinions on that being a possibility?


Someone mentioned that this pattern looking more like heating issues than the other ones. Why?

Would installing a fan control software potentially help with this? If so, why would this happen when waking up from sleep rather than during heaviest use of the CPU? Perhaps I will try to at least monitor the heat for a while.


Perhaps if ours too is a Metal 2 issue, it stands unresolved by Mojave and displays in a unique way on the 13" inch 2012 Macbook Pro.
