MacOS 10.12.4 Graphic Glitches

iMac (Retina 4K, 21.5-inch, Late 2015) Intel Iris Pro Graphics 6200 1536 MB

Have just gone back to 10.12.3 as I can't put up with the glitches any longer and I need to be sure that it's not a fault with the iMac itself.....let's wait and see...

Oh that's great! Please let us know how it goes. I would go back to 10.12.3 myself if my latest backup with that software wasn't over a month and a half old. I gotta get better about doing my backups. 😟

Graphic glitches since macOS Sierra v10.12.4

No graphic glitches since macOS Sierra v10.12.4

I have the same issue with graphical 'tearing'. It happens randomly in all apps (Safari, Sketch, Slack, Claquette), on my MacBook pros display, external Thunderbolt Display and started after updating to 10.12.4.

Keeping the lid of the MBP open while connected to an external display seems to alleviate the issue on the external display. While not a great solution (considering it still happens on the MBP), it's better than nothing. Thanks for the tip.

Has the issue: iMac (Retina 4K, 21.5-inch, Late 2015) w/ Intel Iris Pro Graphics 6200

Does NOT have the issue: MacBook Air (11-inch, Early 2014) w/ Intel HD Graphics 5000

I updated both to 10.12.4 on the same day.

I am having a similiar issue but only on the internal display. External desktops actually don't experience any glitches.

It happens in several application but it is especially visible in PyCharm (Python IDE in Java).

Hoping for a fix...

I can honestly say I'm not surprised, but certainly disappointed. Again, it's imperative that everyone who comes into this thread seeking answers, send a feedback form to Apple outlining this issue to them if you haven't already do so.

I barrowed a friends late 2013 15 inch MacBook Pro for a week and it is not affected by these graphics issues, however another friends 2015 MacBook Pro is as well as my 2015 13 inch air. Has anyone tried a complete from scratch restore, not restoring from a TM backup? any if, any joy with that? I'm giving it a consideration. the only reason I haven't yet is because where Im at for the next several months for a work gig the best I can manage is a 12mbps DSL connection so it will take several days to re-download all my apps. But if others have had luck with this as a fix ill bite the bullet and give it a shot.

DON'T. I manually copied my documents over to an external HDD (No, I didn't use Time Machine), erased Macintosh HD from the Recovery, Re-installed a fresh copy of Sierra and downloaded all the apps again. But the problem still exists.

I have the same issues. Random white lines, mostly on things that are animated (videos, etc.). Started when I upgraded to 10.12.4. I upgraded directly to it from 10.10.x. Never had the problem before.

I'm having the EXACT same results. If I have my MacBook Air 13" (2015ish) open, and then close the lid, it will send to my external display as expected -- but I'll periodically get artifacts exactly like TomasZlin's pictures -- mostly around the menu bar.

However, if I restart my Mac with the lid still closed, upon restart it has no such artifacts. So my guess is it is some sort of glitch during the handover from the MacBook screen > external display.

SOOOOO glad it's not just me though.

So since the start of this thread, and more importantly since I asked everyone reading this to include the model of Mac that's giving them trouble, I've gone back and counted all the ones listed as "having problems". Each and every one of them is a 2015 model. Others have chimed in to say something about their 2013, 2014 or other older computers that aren't exhibiting the issues on the same 10.12.4 software, while only their 2015 models are. This is just a tad worrysome to me, and I hope this isn't another one of those hardware issues like back and 2011-12 happening all over again.

Hey all, just to join in on this, I too have exactly the same issue and I'm a Graphic Designer who's currently experiencing GPU restarts and Kernel Panics on an hourly basis thanks to this bug which seems to be a core part of Sierra 10.12.4! I've filed a Bug Report on the Apple Developer portal but they haven't got back to me or anything!

Also, when this first issue started about a month ago I went down the route of taking my MacBook Pro 13" Early 2015 model back to Apple and they replaced the logic board yet the issues are still here so I can safely say it's software related. I hope Apple are aware of this issue and it's fixed in 10.12.5 or else I won't be a happy customer. As a designer who uses their mac for at least 8 hours everyday, I can't be having GPU restarts and losing work on the hour every hour.

I just wanted to add, that I booted into Windows 10 on my Early 2015 Macbook Pro 13, and I do not get the weird glitches described here by other users. It has to be just macOS 10.12.4. I also reported the issue to Apple.
