Recurring error: A graphics problem has been detected.

Just got the same problem today on early 2013 rMBP. Required a hard reset to unfreeze and then I got the message in loop. Removed the logs, waiting for it to appear again. Very disappointed as I just have installed Yosemite.

To revert to Mavericks you will have to hold command r while starting up computer

if you have time machine you can restore from a backup when the system utilities comes up

note I still had graphic issues after reverting

turns out it was just timely hardware failing just after I updated

wasnt yosemite. Graphics card just happened to start breaking down at that moment

msking it appear like it was yosemite

ive since replaced my logic board at Apple Store

Turning off automatic graphics switching in the system preferences/energy settings seems to have stopped this problem for me. Yesterday I noticed lots of "GPU Reset" log messages in the console app and the system crashed twice. Since changing the setting I have no GPU Reset log messages and no system lock-up. This only happens on Yosemite for me - it happened during the beta and switching back to Mavericks "fixed" it.

Seems like there might be a Yosemite bug related to graphics chip switching for power saving.

That said my system will no doubt freeze in a few minutes.

"moving away the log files and the symlink in /var/db/GPURestartReporter fixed the issue." Where do I find this file /var/db etc. I cannot locate this file to move away. I did find the kernel files in the library section you mentioned that was stated in the logs and removed them. I am just trying to locate this symlink you mention. Thank you.

look in your

system disk / private / var / db / GPURestartReporter

(that folder might be empty on your system)

I cannot find my system disk. However I did find those Kernel files listed in the logs and removed them as per your suggestion--so far with no crashes. How does removing the information from LOGS affect the ability of the computer not to crash? I could not find the Kernel listings anywhere else. Thanks for your help and patience with me.

My system disk has been renamed.

Yours might be named Macintosh HD.

I use an application EasyFind to find that folder

2012 Mac Mini Server ... same message keeps popping up.

I have had this problem, repeatedly, on my MPC Retina (17") since upgrading to Yosemite, and deleting the files as indicated in the original post doesn't solve it.

BUT, this is because the reason I am rebooting (I get the messages at log in) was because my Mac was crashing when running Keynote - either when trying to start a presentation, or when adding a transition/animation (i.e. using the GPU). I don't know why this happened, but delete Keynote from my Applications folder, and reinstalling from the App Store (I had to reboot before the AppStore gave me the option to reinstall) seems to have fixed Keynote, and now I am also not getting the error message.

In other words: it may be important not simply to delete the file, but to identify what app you were running when the GPU restarted, and see if you can reinstall that too.

I am having the same symptoms using a Late 2012 Mac mini with a HDMI connection as a HTPC. I will have the "A graphics problem has been detected" when I activate my system (I have it running all the time). I can close the window (I select report an error) and the system runs fine when I am using it. It is a pain because my remote control isn't setup to deal with this window so I have to grab my wireless keyboard to get rid of this banner. It sits in the middle of the screen blocking what I am trying to watch.

I haven't tried the workaround(s) but I might write an automator to get rid of the window.

So far so good the message didn't come back after I deleted the logs. I really hope this will be the case until Apple comes up with a fix.

Got a brand new graphics board at the Apple Store. Unfortunately, after one week's period of time, computer crashes unexpectedly with the same "graphics" message. Upgrading from Mavericks to Yosemite I thought was going to correct the problem---but it did not! So much for new hardware.

Turning off automatic graphics switching in Yosemite will fix the 'graphics problem has been detected' issue. If you're using any applications that heavily tax your GPU or run a second display, that setting is going to cause problems. My advice would be to turn it off and never turn it back on.

Can you please tell me how to turn off the automatic graphics switching? Will this prevent freezes after the computer "awakens?" Will this allow Photoshop to proceed with crashing? Thank you for your assistance.

to turn off automatic graphics switching in Yosemite:

System Preferences > Energy Saver > Uncheck the dialogue box at the top of the window.

That's it!
