10.10.3 on Mac Mini Late-2012 graphic issues

Ever since I updated 3 of my Mac Mini's (all late-2012 models) I have been seeing graphic artifacts on the screen randomly.

If I move a window over the artifact area, the artifacts go away. I haven't seen this issue until recently after installing 10.10.3.

2 of the Mac Mini's have Core i7 cpu, and the other has Core i5. All have maxed out 16GB of RAM and SSD drives.

Here is a link to a video of the artifacts when they are happening: https://www.youtube.com/watch?v=w1NzMvof0j8

Has anyone seen this, or know if this is an open issue that is being addressed?

i have found turning transparency off in accesibilty in system preferences definetly helps a lot. I've had transparency switched on again the past week since upgrading to 10.10.4 hoping the problem would of been resolved but i must say i had forgot how frequently i was getting these graphical artefacts as they have been happening frequently every day since i have switched this setting back on. I have now switched transparency off again the past day and the graphical artefacts are practically non existent. Suggests to me a software issue but I'm no expert. Anyways give it a try

In some instances, the newer upgrade OS X and associated firmware advances make

reverting (download install previous purchase OS X, etc) an unlikely prospect. One may

hope that if you had a Yosemite OS X 10.10.5 on a suitable boot drive, it may prove the

point one way or another. Install OS X on an external drive.

Since my 'recent purchase' of this Mac Mini (Late 2012 i7 quad-core 2.3GHz server)

is now little over a year old, direct from Apple, the option to try Yosemite has passed.

Some other options to get free software update to the included versions (former iLife

& iWorks equivalent) appears to have vanished from App Store as of last week. Not

much of an answer in these observations, though.

Since I have other older computers which do OK but had no forward upgrades...

I'm rather sorry to not have found a restored model happily running Snow Leopard. 🙂

Has anyone resolved this error? My issue is far worse than most of your descriptions. My system hangs & restarts every time I get the error, which also covers the whole screen.

If I attempt to clear the screen, which must be done quickly, by removing the HDMI cable, I get a bit of "snow" like you used to see on a TV, except colored.

...And then it hangs and restarts. It also hangs and restarts if I do nothing, usually within a few seconds of the original error appearing. I've filed a bug report with Apple as well.

Mac Mini (Late 2012), 2.5 GHz, 8 GB RAM, 500 GB original spinning HD. Mac OS 10.11.3, though I've only recently upgraded. I've had the problem on multiple OS X versions. I don't know the exact time (in relation to OS version) that it started.

Now its becoming really unstable. Restarts randomly. I will try a clean restore to see if it helps. I cant believe every intel HD 4000 Mac does this. If so Apple would have moved much sooner to resolve the situation.

Do you have any links to those other threads?

I was trying to find other threads before I started this one.

I must have been searching for the wrong key words

My late 2012 Mini (2.6 I7 16GB Ram) using a TBD has no graphic issues at all.

Not really try. Apple Hardware test can't fully get into the GPU and thus it can't fully test the GPU for hardware problems.

Totally seeing this problem in my 2012 Mac Mini as well. 16 GB of RAM and added an SSD as well.
