Mac OS 10.13.4 wake up screen glitch

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?

-Macbook Pro 13" - bought: september 2017

I'm from Brazil. Sorry about my poor English.

Yup, mine is also a mid-2012 Macbook Pro, and I'm seeing precisely the same symptoms after upgrading to Mojave (among other issues, but that's another story). Sometimes the it gets better when I go to Settings-->Accessibility-->Display and check/uncheck the "Increase Contrast" button. Other times I have to reboot. Super annoying!!

Yes. Apparently, they fixed newer Macs and broke older ones. I have the MacBook Pro 13-inch, mid-2012, and I have the same wakeup issues since upgrading to Mojave. Furthermore, due to an unrelated issue with Photos being stuck on "Uploading 39 items", I completely wiped my Mac by re-partitioning and restoring 10.14.1, and the issue persists. Once it gets to what is supposed to be the password screen, objects like the account photo and buttons are just large white boxes, and the rest of the screen is either blocks or a large circular pattern of garbage. Once I put in my password and get to the desktop, it looks a lot like your photo, and varies a bit from time to time. Besides the snowy noise patterns, I also noticed the last time it happened that there were little crosshair-like plusses all over program windows that were open. I am unable to navigate well as the menus only flash the text on them for a second before presenting just a garbled box, so I have to click on where the Apple should be a few times to get my bearings as to where Restart is, to be able to click it. Restarting is the only thing I can do to fix the issue until it happens again.

That's what I assumed at first, especially since this device, in almost 4 years of ownership, never did anything of the sort prior to Mojave. However, since upgrading, I have performed a complete reinstallation with Command + R to boot and using Disk Utility to repartition, with the same result.

Certainly has been problematic & not much way to tell what percentage has been fixed, though I'd guess it's lower than in the past for the time frame. 😟

Just thinking, if it messed up the EFI or Firmware on the 1st round, that would seemingly make it a mixed mess to fix or not.

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.

I hope it's a software issue and not hardware issue but any way, it's been to long since this is happening, shame on Apple for not fixing it. It's embarrassing to open the laptop in front of a customer and to see this happen and since it's a random issue, you are playing lottery each time you open the lid.

I had the same issue on my MBP 13" mid 2012 using Mojave.

The fix was back to High Sierra (sadly).

I do not know why Apple says that Mojave is compatible with our machines but finally it is not.

In my case I upgraded my MBP with a Samsung SSD. Sometimes I thought that it could be the problem, but I have not tested with the old HDD.

Could be a problem recovering the screen status from the swap memory?

It is a really shame because Mojave works fine but when it wakes up.

Please, Apple, do a fix for this in order we can enjoy the real dark mode!!

Anybody knows if do we have a fix for this issue in Mojave?.

Is there any bug update in Mojave that could fix this problem?

It is a bad customer experience that Apple list our devices into the Mojave´s supported platforms and you have to shutdown the entire computer after every wake up.

Thanks a lot in advanced.

I would like to move to Mojave to work on dark mode.

Do you know if there is a way to refresh the screen to recover the right screen behavior? I have to reboot and I loose everything not saved.

Or, do you know if there is an alternative to work on dark mode under HighSierra?

Thanks a lot for all your support.

I replaced my 2012 MacBook Pro with an SSD and 16GB of ram, full of standard ports, and it works better than the majority of current PC laptops on 2019.

Please, Apple listen to us and fix the issue in Mojave with our screens after wake ups.

Hi,

I just upgraded to Mojave and I haven't seen the issue yet (knock on wood)

Here's my specs:

MacOS Mojave

10.14.2

2017 MBP 2.3 i5

8 GB Memory

Intel Iris Plus 640 1536 MB

Thank you for the reply!

Ben

I can not understand why apple does not fix this issue if it appears in MBP 2018 too!!!

I supposed it was something related to old machines.

Perhaps just a keyboard shortcut to refresh the screen and recover the status was more than enough.

Does Apple read this forum?

I just purchased a new 2018 macbook air (mojave), and this exact screen has happened twice on a wake-up from sleep (both times in the AM after 8-10 hours of non use), so it isn't only old machines using a new software... have we learned anything?
