Q: 10.10.3 on Mac Mini Late-2012 graphic issues

Nope' I have not seen that with 10.10.3 on my 2012 i5 Mini with 10GB of RAM and dual 21.5" Samsung monitors.

1. You have quite a few folders and other stuff on your desktop.

(it shouldn't matter, but I move those folders and other stuff to Finder and keep my desktop clean)

2.. Are you a gamer or heavy graphic's user?

(I see a folder for Minecraft on your desktop)

I'm not a heavy gamer, but I do see the temperature of my "Intel HD Graphic's 4000" go way up when I run light games, video's and do video editing. To keep the my graphic's and cpu heat in check, I use a fan control diddy called Mac Fan Control.

Yup..on all 6 of my offices Late 2012 Mini's w/16gb memory (1gb Intel 4000 Video) we're getting the exact same graphic glitches. Has nothing to do with heat. There are a couple other threads out there with similar issues btw.

It's annoying for sure but we probably won't see a fix until the next point update.

If it gets too annoying I've thought about pulling out the last good working Intel4000 kext from one of our pre-upgrade time machine backups.

My Mac Mini (late 2012) has the same issue, started a few weeks ago.  Now I have a new one: the "unexpected shut down".  I believe both issues have some kind of interation.

Apparently other users of the Late 2012 Mini i5/i7 have experienced a graphic issue

after upgrading to Yosemite 10.10.3. So far, mine is still at Mav 10.9.5 (shipped 10.9)

I've had this one, six months. From Apple online; new clearance stock, quad server.

So perhaps there may be some firmware or other update needed to remedy this issue.

It seems that many users have the same issue, in every Mac computer having the Intel Graphics HD 4000 as GPU.

I've a Mac Mini Late 2012, dual disk (SSD Crucial MX200 250 GB and WD 500 GB 7200 rpm) and 16 GB of RAM (Crucial 2x8 GB 1600 MHz) and I've the same problem!!!

I went to Genius Bar and an Apple genius checked the hardware and confirmed that my Mac Mini hasn't any hardware problems, so it's obviously a software issue, perhaps a graphic driver problem, introduced with Yosemite 10.10.3.

Apple has to fix it because there are thousand of Mac having this issue!!!

Please, open a ticket to Apple, explaining the problem, here:

Is there a way you could revert to an older OS X version, such as the one the unit shipped with

(and may still be available for download from the App Store, as a result) by using a new install

of that in a partition or perhaps on external drive that could use the Thunderbolt port with an

enclosure that could support faster data speeds than USB3.0; maybe with 7200-RPM HDD or

an SSD? -- I ask this, because my Late 2012 Mac Mini is equipped with a second internal HDD

however both stock with 5400-RPM rotational drives, but this gives me upgrade opportunity to

put a later OS X on the second identical 1-TB internal hard disk drive, and not disturb 10.9.5.

Part of the reason I bought the server model i7 2.3GHz quad core was the second internal HDD

and the ability to upgrade RAM to 16GB; and that it did not ship with Yosemite. Apple was unable

to tell me which OS X was actually installed in the clearance-section new-old-stock Mini, and so

I almost did not open the box. I did search online via serial number lookup and that told me the

unit I bought direct from Apple contained Mavericks 10.9.0; I'd hoped for Mountain Lion 10.8.0

because the base RAM included was only 4GB & older OS X run OK with less initial memory...

So since I have this unit, I am slowly using it instead of the much older Macs with older OS X that

I have; but still use Leopard 10.5.8 in both Intel & PPC Macs. And older 10.4.11 clones for some.

To have a retro installation of the older as-shipped OS X version may be helpful to use the Mini

you have, if you have supported hardware to practically make use of a second system; with either

another internal hard drive or an external set-up that won't bottleneck useful data transfer speed.

In any event, I feel your pain. Sometimes hardware configurations can exhibit odd issues when

using different makers installed parts; and the graphics is supported by a percentage of the main

RAM. Not sure if weak memory chips could affect graphic performance in this kind of situation

where system RAM is shared by GPU. Under a load, strange things have been known to happen.

And some upgrade paths may or may not affect the situation; a fully upgraded Mini should never

have the issue where basic graphic visuals appear incorrectly as evidenced by some users; nor

should the original configuration (if reverted to older OSX) make a difference, without a load.

Good luck & happy computing!

yeah I've been having this issue a few months now on a late 2012 mac mini 2.3 i7, 16gb of RAM with the 4000 graphics chip. Also had a few random shutdown/restarts as well over the past few months.I reduced transparency and it made a bit of difference, certainly better than before. Was worried it was a hardware issue as my applecare runs out in january 2016 but judging by this thread and a few others it seems it maybe more a software issue. Updated to 10.10.4 and put transparency back on now so will see if the issue is still there. Will keep you posted

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

well still there, so the update hasn't fixed it. regards

Hi all!!!

I've just downloaded the "Apple Service Diagnostics v.3S151" (for Mac Mini Late 2012 and other Mac machines) and I've created a bootable USB Pendrive.

I run all the tests both if EFI and OS mode and all test have passed, so it's another confermation: my Mac Mini Late 2012 (and all your Mac machines having Intel HD Graphics 4000 as GPU) hasn't any hardware issues, but the problem is in the software!!!

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.
