Mac OS 10.13.4 wake up screen glitch

I have the same question and I solved it. I installed an App called "Duet" and I assume that you have it too, or maybe some similar App which messed with your screen.

Here is my solution:

1. uninstall this kind of App
2. open System Preferences -> Accessibility and select the Display tab, then uncheck the Reduce transparency if you checked it before

Hope this could help!

Fingers crossed there may be an easy fix... it hasn't happened for a week after my IT guy at work made a recommendation. When I had the diagnostic done at the apple store, the only thing he noticed was that Chrome was open 6 times (which was the number of times it went green) when it went to sleep. with that the "apple diagnostician" recommended that I use "Chrome Canary" as it interfaces better with Macs. It then happened again about 24 hours later (using Chrome Canary). My IT guy at work said "always go with the low hanging fruit". He suggested that I go to the 3 dots to the right of the screen on Chrome, then to settings, then to advanced, then turned off "Use hardware acceleration when available". It's been a week, and no more green screen! I'll repost if it happens again.

Hi, i've noticed that the glitching stops when i desactivate the automatic graphics switching in the energy saver setting. Check thread/8492251for details.

try this, it may help.

Still having this issue when MacBook is woken from sleep. It only happens when the battery is dead, in my case.

Logging out and logging back gets rid of the glitches until the next time the battery dies.

• Mojave 10.14.1 (18B75)
• MacBook Pro (13-inch, Mid 2012)
• 2.9 GHz Intel Core i7
• 16 GB 1600 MHz DDR3
• Intel HD Graphics 4000 1536 MB

I gave the last chance to Mojave in my macbook air (mid 2012) during Christmas and I do not know the reason, but now it seems that it is working fine (cross fingers).

I did an SMC reset after upgrading to Mojave and I have wake up the computer several times daily without problems (from 10 days ago).

I do not know the reason but perhaps the Mojave 10.14.2 has some bug fixed related to Metal/intel gpus/ or SMC managing that seems to fix my issue.

I suggest all of you to test a deep SMC reset: https://support.apple.com/en-us/HT201295

I have to say that I replaced the original HDD with a Samsung SSD 512GB in my MBP and several times, the computer wakes up with a full reboot instead of recover just the login screen. Perhaps the full reboot is hiding the issue, but using an SSD, a full reboot is really fast (and I had the issue before that forced to reboot using the ON button for 10 seconds).

If I get the issue again, I will post it here.

Good Luck.

lordnishant.l, your screens issue does not seem very in line with the specific screen issue we are talk of about. Yours may not be a software issue, as most of us are deducing ours is. If you can get your computer, namely graphics card, checked for free then you should definitely get that done. Most wierd artifacts on the screen in general (glitches, discoloring) are related to failing or broken graphics cards and they tend to get worse over time.

I am now back at 10.13.3 because the wakeup error is missing.

Mojave also fixed this for me. Thanks to all in this thread!

Regarding the people who have "fuzzy" screens with still moving square-shaped cursors after waking from sleep. I'm encountering the same issue. I've got the feeling it's a driver bug related to Intel iGPUs. I'm fairly certain it's not a hardware failure because the exact same issue happens on some Windows laptops intermittently after updates and requires either a vendor approved patch or driver roll back to fix. It's only happened twice after many sleep cycles to me and I'd be more peeved if it cause loss of work. Apple's product line is smaller, but I'll give them a pass this time due to possible software/firmware complexity.

There is no fix yet. Everyone has to call in to Apple and not just post here. Hopefully they will address this with the new OS.

To capture it, have your iPhone READY to take a video when you open the lid!! I've caught it a dozen times... then call Apple. Then talk to a supervisor and have them send you the link so you can send in the video to engineering. We have to keep reporting this so they do something about what they're calling 'an anomaly.'

Nothing so far. I reset the NVRAM, SMC, and reinstalled OS twice. Waiting for 10.14 I guess. But in the meantime, call Apple to report the glitch! Take a video! Have a senior advisor send the link so you can send the video to engineers. We have to report directly to Apple, not just here to try to get them to do something about it.
