Q: Recurring error: A graphics problem has been detected.

Yes. Unfortunately, until Apple admits that there is a problem with their software (specifically, Yosemite), the majority of hardware replacements are going to be a waste of time. And, for people living in countries that do not have a local Apple Store, having hardware replaced, when it is most likely not a hardware issue, is a huge undertaking and a big inconvenience. But, not doing anything about it while their product is under warranty, on the outside chance that the problem is due to faulty hardware, is risky. This is a terrible position for people to be in and I hope the smart folks at Apple come to this realization, fast!! And, hopefully, soon, the Apple "geniuses" will quit stating that they "have never heard of anyone having this issue!"

While I know this may not pertain to everyone, I had this happening on my Mac Pro (Early 2014) and none of the "solutions" mentioned in this thread  worked for me. I was able to detemine itw as software not hardware, since booting from another disk with Yosemite did not produce the error.

Aftr exentsive trouble shooting I determined it was an extension I had installed ( left over from Mountain Lion/Mvaericks)  It was called  Kick Start and was desigend to "kickstart" all my widegets, after removeal I have not had the error re-occur

Hope this might help someone else.

It happened to me again (this was the third time in total). Didn't do much but browsing - only two tabs open. The power cord was plugged in and there was no change in power consumption (like switching to the battery).

I better follow Apple's instructions to get this thing to an approved Apple reseller, so they can have a look at it..

Try to check "Reduce transparency" under Accessibility -> Display. I had no crash since two days and a significant improvement in UI performance. I don't believe that this is a fix but maybe it helps to reduce the amount of errors.

Hello John. Did it really solve the problem? I always thought software or plugins can not cause a kernel panic error? I was told it could only be yosemite that directly communicates with the hardware?

I don't think the error is really a "kernal panic" error, but rather interaction with the graphics card and OS (this is not to say that it couldn't be a HW graphics card problem for other users) , anyways it's been about 10 days and a half dozen restarts ( to continue testing) and I have not had it re-occur, if it does I will be sure to update my post.

I had this error now 3 times. over a period of 1-2 months. Not sure what to think... Apple Helpline told me to bring it in for Diagnostic, and they think it could be a, very likely, be a hardware defect.

Maybe Apple is holding back because it is a hardware problem and trying to figure out how to best solve it instead of recalling all laptops?

I have a mid 2014 Apple Mac Book Pro Retina.

fixed my issue

I thought it solved mine also, but then it started happening again after about a week.

Flips01 has it right on.  Constant rebooting from my mid 2011 imac, and report a problem with graphics  Went to computer/library/logs/diagnostic reports and delted all the gpurestart entries.  Immediate response and back to working as normal.

Wish that had worked for me.

Having the same problem on a refurbished mac pro (late 2013). Exact same error message. Taking it in to genius bar to make sure the video card is ok. Has ANYONE from apple responded to this issue? The phone tech had not heard anything about it.

They always say they haven't heard of the problem before. You might point them to this thread.

so this error happeneed again last night, so I kept it frozen and turned on and delivered to my local apple authorized service provider (same as first time), so they could see and experience the error themselves. i have never seen a technician looked so blank before. he also said he didn't know what to do. I also called Apple support and asked them to just take my now 1 month macbook pro in. but they won't do that directly because it's over 14 days of age. sigh... I also found a pixel error in the screen, and some days ago when browsing the top of the screen became pink ehen loading a page in the safari browser.

Deleting all crash logs didnt help for me (mac mini 2012 as media server, connected to yamaha receiver via HDMI)

Panic error and reboot happen almost every day at night when I dont use my mac! Such an annoying issue with this Yosemite..

Also I have an error in logs every few seconds:

Jan 20 19:23:19 al04.local ReportGPURestart[60099]: gpurestart_header:  gpurestart_message

Jan 20 19:23:19 al04 com.apple.xpc.launchd[1] (com.apple.ReportGPURestart): Service only ran for 0 seconds. Pushing respawn out by 10 seconds.

What could it be?
