Recurring error: A graphics problem has been detected.

It should resolve the graphics/display issues you've been having since upgrading to Yosemite. I didn't experience these specifically but I had similar issues which are now gone.

Yep - since I've changed this setting I've not had a single crash/freeze (over a week when it was crashing daily).

System preferences, Energy Saver (go figure!) - it's then the first check box - deselect it.

I'm on a 2011 Mac Mini with the same issue, but I think the dialog is different since I don't see any option for automatic graphics switching.

Yeah that option is only on i5 and i7 MBPs. You can try "Reduce transparency" in System Preferences > Accessibility > Display. That seems to help some people having display issues with Yosemite. There are a number of threads talking about this issue so hopefully there is an update to Yosemite or a GPU driver that provides a permanent solution.

This happened to me too. Apple replaced graphics card/logic board then LCD then clean install and I'm still getting crashes and graphics error 😟 1yr old iMac unusable!

My 27" iMac (2010) has the same issue since upgrading from Maverick to Yosemite (full version). Sometimes it becomes unresponsive after the "report" button is clicked, where the mouse still moves but you cannot click on anything. Then it resets itself about three times, asking for the user password, before becoming functional again. Not useful if I'm in a hurry.

Glad that you at least reported the problem to Apple, hopefully within your warranty period. My 2010 iMac had similar issues on/off since the beginning, but I tried all the remedies to fix it myself and Apple would have nothing to do with it outside the period. Four trips to the Genius bar, multiple overnight stays while they ran diagnostics, and could never figure out what was wrong. As they called it, they were unable to replicate the problem. So it's good that you at least have a record of this problem. Now the problem has crept back up for me in the form of this error as well as the computer being unresponsive as it resets itself.

Unfortunately it didn't work for me either.

I'm having the same issue on a 4 month Mac Pro Late 2013 since after updating to Yosemite and only when running BOINC, where some projects make use of AMD dual graphics. There's no system crash of freeze, just that **** popup while BOINC keeps running (those GPU-based projects too).

Apple Diagnostics gave back a zero hardware error, tried it three times at least since that popup appeared.

I'm thinking to reinstall Mavericks to check if it's a bug in Yosemite.

Finger crossed.

I have the same problem as well on my late 2013 rMBP, What happens is my computer freezes and is unresponsive, so I have to shut down manually. Upon booting back up I get the "graphics problem has been detected" message. I will try to de-select graphics switching to see if that helps. Nothing came back on the hardware test, either.

I'm having the same issue on a 2014 15" rMBP. I've noticed that graphics switching is *very* glitchy. I've avoided turning off graphics switching because of battery life, but the random freezes and crashes are too much. I guess I'll turn off the switching and wait impatiently for a fix from Apple.

Turning off the automatic graphics switching didn't solve this problem on my 2012 MBPr. Oddly, I only get the error when I log into my admin account. I normally run in an account that does not have admin privileges, and I don't see the error then.

I'm on a 2011 Mac Mini and was having GPU crashing issues. I spoke with Apple after I had run the full hardware diagnostics for a couple of hours. I booted into Recovery mode and did a Verify & then Repair in the Disk Utility. Interestingly, the Verify did return several files mentioned in this thread with the wrong permissions. After Repair, I booted into full OS X and followed the steps to remove the .gpuRestart files and the symlink.

My Mini has been stable on Yosemite since then.

Yep. Late 2012 Mac Mini here (2.5Ghz Intel Core i5) on Yosemite, latest build. Hooked up with HDMI. Error message doesn't pop up while I'm using it, only when I turn on TV or switch to the mac input on my receiver.

Removing those db files didn't help. Turning off transparency didn't help. I don't have that Energy Saver option mentioned, even though i'm i5... Reinstalling Yosemitie didn't help.

Reporting the error every time but this is getting very frustrating.

@changepace, late 2012 mac mini (2.3GHz i7) here. Same set up, same issue when switching HDMI sources. Super frustrating!
