MacBook Pro (Retina, Mid 2012) freeze with Yosemite

For people reading this: The update restarts the system multiple times and takes quite a while!

2 times a full reboot. After that it displays a grey screen and does a final update round of about 9 more minutes.

During the update I'd left the room to do other stuff. It had plenty of time! This was definitely a problem with Yosemite and not my patience! Although I would admit that my patience is running thin with Yosemite.

Symanski I wasn't making the remark towards your reaction. I just wanted to post a warning for everyone about to embark given my experience installing it.

Couldn't agree more on everything you said, my patience regarding Yosemite is pretty much non existing after months of this sh** and Apple not even acknowledging that the problem exists.

Just assuring you that I did wait! No offence taken; we're all looking for the same thing - a fix from Apple.

I'm less than impressed by how long this very serious problem has gone on for. It's having a serious impact on what I feel safe to work on with the MBPr just as I don't want to encourage another crash.

Just so you guys know, even with the downgrade to Mavericks I get graphic crashes 😢 ( Never had that with Mavericks before...)

I have the same problem. Mouse work but everything else freezes.

My config: Macbook pro Retina, Mid 2012.

I do also encounter an other problem. When the screen freezes, it takes about 2-3 minutes before the Mac turns it self of (no interference by me). When i try to start the it again, it would not boot. I have to do a clean install. It takes about 7 days + - after clean install, and the mac crashes because of the graphics and would not boot. Does anyone encouter the combination of graphic-card switch fail and OS X not booting?

My mac is at service now, and the service people just did a clean install and said it`s now working again.! (I told the service people that I already did a clean install, and the respons I got: The Apple Diagnostics system didn't show anything wrong).Thats about 200 $ for a clean install of OSX, nice.👿

Well : the short version of my solution : electrically insulate between the motherboard and the fan (thunderbolt's side).

I recovered yet the full use of my MBPR mid 2012 retina including connecting 3 external screen at the same time, putting in standby, and wake up while an animation itunes was playing, play with gfxcardstatus,...

Not even 24hrs and another crash. Total crash, not even the caps lock was changing on the keyboard. It decided to reboot itself.

Again, rebooting I get a black screen. Seems that to get round this you've got to shut the lid, disconnect the power and wait a couple of minutes. When you switch on you can see the OS hastily sorting out the windows. And they're all truncated to from the right too as if wherever it was putting the screen originally wasn't wide enough for them.

Up to that point 10.10.2 was looking a bit better.

You might get better advice in the forum entitled: "My hardware is totally hosed, but I think a software update will fix it."

Strangely my hardware became "totally hosed" just as I upgraded to Yosemite.

Today i tried to freeze my MBP late 2013 on 10.10.2 usual way - by switching on/off "Automatic Graphics Switching" checkmark in Energy Saver section.

And i failed. I could not freeze the laptop. Tried about 200 switching (usual about 20 is enough). And animation of checkmark has some changes. It looks like it has a little lag. It wasn't there before.

Can anyone try this out? Hope Apple did some changes in driver.

I also have the problem this thread was originally intended to address: freezes in Yosemite (with cursor still moving) associated with switching between graphics modes. I was able to get weeks and weeks of uptime on my mid-2012 non-retina MBP by keeping automatic switching turned off.

I upgraded to 10.10.2 and turned switching back on. So far after numerous graphics switches I am not getting any freezes, but we'll see....

I finally could hang the system with only cursor still moving by switching between cards.

So, 10.10.2 didn't solve the problem.

It's pity.

I had bought the 2012 MBP with 750GB SSD, 16GB RAM and Turboboost (for whopping $3300). I was hoping computer would last few years! I am now getting major problem of black screen. I went to Apple Store, the tech said it is due to water damage and I have to $1200 to fix it. I erased the HD and then re-installed, it started working again. How was this a water leakage issue?

Same here.

Same here, just found this thread today and I am happy that I am not the only one who has this problem.

I had the first freeze and total crash today. Before my macbook "only" suffered from GUI lags while changing spaces, using Exposé etc.

Is there any comment from apple to this problem?
