Mac Wake Up Screen Glitch

What fixed this was resetting the PRAM or NVRAM by following these instructions.

Reset NVRAM or PRAM on your Mac - Apple Support

I had migrated my MacBook Air 13" to the new MacBookPro 15" and the screen was trying to be a MacBook Air.

Also, I had to search to figure out how to change the computer's name - it's under Sharing in System Preferences.

A Troubleshooting Procedure that may Fix Problems with macOS El Capitan or Later

You should try each, one at a time, then test to see if the problem is fixed before going on to the next.

Be sure to backup your files before proceeding if possible.

To provide more info, on my laptop, I had to go back four times. At first they insisted that it had to be a hardware problem. They replaced the top case. Then they said it might be File Vault encryption. Turned it off, didn't work. Then they replaced logic board and did a clean OS install. This past week, they told me that their techs concluded that its a problem in the OS (High Sierra) and that there is an internally issued memo not to take any more machines for repairs because they do not have a fix. They said that they're working on it but have no information about when there will be a fix. The genius guessed that it might be fixed in Mojave, but they don't know.

I answered Styna's post above... Both of you guys - take a video(s) of when it happens and then call in to Apple Support and get a senior advisor and make sure they send you the email with the specific link so that you can attach and send in the videos for them to send to Engineering. We have to get more of us on this for them to make a move! Thanks.

I'm having the same problem with my new-to-me refurbished 13-inch MacBook Pro, but my screen is a textured beige screen. I just got off a chat with support and they said to do the following:

(1) Reset the NVRAM or PRAM

(2) Reset the System Management Controller (SMC)

(3) Use safe mode to isolate issues

(4) Reinstall OSX

Has anyone had success with this? My frustration is I spent a lot of money on a new MacBook Pro and feel like I got sold a lemon. I shouldn't have to do any of this kind of maintenance when it's less than 3 weeks old. I'm tempted to just return it under warranty since who knows what other glitches this thing has.

I was having the same issue. Mine would also shutdown immediately after logging in.. I took to apple customer care. They said that it was caused by dust in the logic boards or inside system. They cleaned it. Reinstalled macos..the problem hasnt happened since then

Oh my! Well Apple? There’s more and more people with the same problem!!! Clean install(s) didn’t fix it! Logic board and screen replacement didn’t fix it! Please at least acknowledge this issue and let us all know if it will be fixed with 10.14.

In the meantime - everyone with this issue also has to call in. Get to a supervisor. Take a video of it happening with iPhone. Have them send you a link so you can upload it for engineers. Squeaky wheel is the only way! Thanks!

Right? I urge you to call in to Apple. Take video of it ( while you’re holding your breath) w your phone - and get to a supervisor at Apple who will send a link so you can send the attachment to engineers. But so far resetting SMC, PRAM, and entire OS has not worked. I’ve also read replacing logic board, screen and battery hasn’t either - so don’t send it in. But the more people who send in the video the more they’ll know it’s still a problem! Agh.

I have this same problem. My Mac 12" is on High Sierra 10.13.6. I took my Mac to the Apple store for repair. I was told its a High Sierra software issue that affects some computers, but not all, even if they are of the same model. They could not explain why my particular unit was affected by the issue when other Macs, different models and the same model also running High Sierra, were not. They told me that they cannot send computers afflicted with this problem for repair, and they were working on a fix. They could not tell me when the fix would be coming. Frankly, this was dissatisfying and disappointing. Apple should get out in front of this and give its customers information about how they will be resolving this. Instead, I'm uncertain when or if this will be fixed. Apple should be doing more for its customers unlucky enough to have gotten a unit that was vulnerable to this software issue.

They told me no fix yet. And they couldn't tell me when there will be a fix. They told me that they were told not to accept laptops for repair because they didn't have a fix and there was nothing they could do. If I were you, I would go back and get a new machine if you still can. "Glitch" is being too generous. Its a recurring defect.

Open up finder and make sure the desktop png file is your correct background and now the snowy glitch

Library/Caches/com.apple.desktop.admin.png

That file was a snowy screen instead of my actual desktop background, once I changed my desktop image and restarted my computer all was well, hope this helps

I have this same trending problem with my MBP 13"2016, Touch Bar, Four Thunderbolt 3 ports, flash storage, Retina display, running Mojave 10.14 that I purchased May 2017. This only started for me AFTER upgrading to Mojave. However, intermittently, the screen will be a grayish bars-and-lines similar to a small type grid paper. I have never seen any colors. I'll open it 5-8 times with no progress, but the mouse cursor always shows up as another white-ish block... Then will randomly open fine, and I can carry on.

The only thing that seems to help it is unplugging the power. Seems fairly quick to work after that.

I'm not a tech guy. So, hopefully this helps to some degree.

Best,

M.

I have this issue, too, on a new 13" MBPro! Two to three seconds of pinkish-purple static screen after waking up from a long sleep. Already brought to 'genius' twice who ran diagnostics - it's not hardware. Already reinstalled OS twice, that didn't help either. They're calling it a 'cosmetic anomaly' and have no solution... In my book an anomaly is "something that deviates from what is standard, normal or expected" - and if a brand new computer was on display at the store and didn't perform as expected, they wouldn't sell it. But they did. I hope everyone with this anomaly reports it so that we can get a FIX and not just a shrug claiming there is none.
