Q: MacBook Pro (Retina, Mid 2012) freeze with Yosemite

I have tried the trick with enabling reduce transparency, but after one day, I had a freeze again. So this didn't work for me.

This is a dropbox issue. Try updating the dropbox app.

You must file a radar with Apple! Go to https://bugreport.apple.com/ . Complaining on this thread does nothing.

Anyhow, I am also having this crash on a 2012 rMBP. I get messages that say there was a graphics error that popup when browsing intermittently. These have been sent to Apple. I have also had about 4 total system lockups. The logs show this is a gpu problem. I just filed a radar. The more radars they get the more likely they are to fix this issue. The only other option is to downgrade to Mavericks, which I'm seriously considering.

I have also this problem but on iMac 2010. what I need to do?

I've been following this thread since I upgraded to Yosemite.  I have a 15" MacBook Pro Retina mid-2012.  As soon as I upgraded to Yosemite, I started having graphics issues, freezes, reboots, up to 10 times a day.  Before upgrading to Yosemite I never had an issue.  I tried all the fixes, locking the graphics to one card or the other, reducing transparency, etc..  I could no longer use my laptop at this point as it would continuously reboot.  I also rolled back to Mountain Lion (and Mavericks) and experienced the same issues...  I also waited until 10.10.1 came out hoping that would help, it didn't.

With no other options (and since I had Apple Care) I made an appointment at the Apple Store.  They kept the MacBook and called me a day later and said they were sending it off for repair.  I got it back 3 days later and I have not had a single lockup/freeze/reboot in 4 days.  They replaced the logic board and a hard drive cable (this wasn't listed on the repair but the guy @ the Apple Store said they did).  I should also add this is the second time my laptop has had the logic board replaced.  Not sure this is the exact same issue you guys are seeing, but thought I'd add to this thread in case it helps anyone.

JUST UPDATE JAVA...

Just did that, reboot and its fine....

I don't have Dropbox installed, and I have the newest JAVA Version installed, but I still have freezes, when the GPU switches. So the only Thing working for me is to disable the iGPU.

I'm having the same issue with 10.10.X where the entire OS becomes unresponsive requiring a hard reboot. It only started with the 10.10.X update, prior to that, 10.9.X worked without issue.

I've mainly notice the issue happening with Chrome (my primary browser), Photoshop and Preview.app (with very large images), all of which cause the graphics switching that many others have indicated. I too have submitted hang reports to Apple very time. Hopefully, Apple or someone else can get to the bottom of this and provide a fix. It's a very annoying issue.

MacBook Pro (Retina, 15-inch, Mid 2014)

2.5 GHz Intel Core i7

16 GB 1600 MHz DDR3

Intel Iris Pro 1536 MB

NVIDIA GeForce GT 750M

I did encounter the same problem filed a bug as well. Thanks for the link.

Are you all able to watch netflix in safari? I am not. Doubt its related but the HTML5 player doesn't work for me.

I did the Reduce Transparency in Accessibility six days ago and haven't had another crash or video corruption. 

Macbook Pro Retina 15" mid 2012   Nvida 650M video GPU

Upgraded immediately from clean install of Mavericks. Then did PRAM reset, SCM reset, file permissions repair, disk verify, diagnostics, turned off translucency. None of that helped.

The only thing that has helped is to turn off the GPU switching. That is an answer, but it's not a good answer since it's going to drain power a lot quicker.  I mean, it's a laptop. I'm supposed to use it on the go, no?

I have noticed another issue, which is probably related to this one:

One animation is lagging / stuttering, when the GT650M is active, but every other animation is running fluently. The strange thing is, that the same animation is running fluently one the iGPU.

Here is a picture, of the animation, which I mean: http://i.imgur.com/ajHSbLH.jpg

Could someone confirm this problem?
Btw: I have already tried to reinstall itunes, but nothing has changed.

Hi all,

I fully reinstalled my rMBP mid-2012 (I mean full reinstall with hard drive wipe etc.) and it worked pretty well for 3/4 days. It just started again with the very same GPU panic.

I have an appointment at the local genius bar tomorrow and I will tell them how much I'm ****** off by this, and request an exchange (who knows)... I paid for a 3 years warranty and get nothing in return... Apple is no longer what it used to be if they can't fix such huge issue after more than a month !!

Hi

Im using the late 2013 retina pro with the Nvidia GPU upgraded to Yosemite and had the same problem on an average 6 times in an hour while working on design related applications and yes it stopped freezing when i disabled the GPU switching, tho this dents battery life major!

Funny i thought this was meant to be a more stable and better version of the OS.
