iPhones/iPod Touches/iPads all have a Unified Memory Architecture which mean that both the CPU and GPU share system memory. There is no dedicated video memory on these devices. The advantage is that you don't need to worry about running out of video memory for your textures or vertex data (your app will be terminated by iOS for using too much memory before ...

Repeated kernel panics occurring without third party drivers can only be caused by a few things: 1) A peripheral device 2) A bad OSX image or bug in OSX itself 3) A hardware problem In your case, it is unfortunately (3): System model name: MacBookPro6,2 The kernel panic indicates that your GPU is failing. This is a known issue for your machine. ...

Solved: Booted to Single-User mode and disabled Radeon GPU. Details of investigation: Initially I suspected hard-drive corruption and went about trying to remedy that. Unsuccessfully, I tried the following, with each continuing to hang as described above: Safe boot Boot into recovery (including Internet Recovery) Boot from install media on USB drive Boot ...

In the WWDC 2015 video "What's new in Metal, Part 1", Rav Dhiraj from the GPU software division states at 8'40" Metal is supported by all Macs introduced since 2012. (Nvidia, AMD and Intel) This means : Intel HD Graphics 4000, Iris 5000 & 6000 family, nVidia GT 600M, 700M family, AMD R9 M family,

Finally!! ( in 2015...? ) MacBook Pro Repair Extension Program for Video Issues http://www.apple.com/ca/support/macbookpro-videoissues/ I hope this helps everyone.

Yes the GPU panics are almost certainly due to a defective discrete GPU card. I have the same 2010 MBP and have noticed 10.9.3 has increased the frequency of these fatal crashes significantly. I'm using the gfxCardStatus utility to turn off this discrete card whenever possible but many apps force it on.

you definitely should try this one: http://www.asyncro.com/2014/03/24/macbook-pro-discreate-graphics-card-issue-fix-updated/ I’m writing this reply from my until-now broken MacBook Pro 2011 dammed GPU piece of technology. You'll get away working without the AMD GPU, which vs. having a dead USD$2k… paperweight isn't really a bad deal.

I'm having the same issue with GPU on my MBP 2011 and was using the same solution as yours (plus additionally disabled AppleIntelHD3000Graphics.kext). Saving money for motherboard replacement (or the new Haswell MBP whatever)… I'm able to play most of videos with Miro player. Although, I'm starting to have difficulties with my eyes since it's not possible ...

It depends what you mean by: use them both at the same time So, Apple's usage of two GPUs is based on using one or the other, not both. Meaning as a user, you cannot "use them both at the same time." Now, if you're talking about using them both as a programmer, well then anything is possible, and you could probably target both GPUs using OpenCl. Most ...

Though I didn't experience the blue screen, this does sound a lot like the issue that I described in Boot hangs on grey screen (even when booting from USB drive with fresh OS X install) (I posted as a different user since I didn't immediately have my StackExchange credentials handy). It seems there are an increasing number of people experiencing failure to ...

Your model has only the Intel HD 4000, so you can't use CUDA Full specifications: http://support.apple.com/kb/sp649

You did right so far. But you have to move all ATI files from that folder as well. It will work after that, but the graphic will be slow. Make sure to boot in verbose mode (Cmd-S at startup). mount -uw / (to be able to move System files) mv /System/Library/Extensions/ATI* /System/Library/DisabledExtensions/ Note that the Folder DisabledExtensions needs ...

gfxCardStatus can do this — when the GPU changes, you'll get a notification: You can see the dependency by clicking the menu bar item. It also works the other way round — you'll get a notification when it switches back to the integrated graphics.

About dialog displays only the primary built-in device not the discrete, accelerated GPU. To be sure, run: system_profiler SPDisplaysDataType in the terminal. On my mac, the About dialog shows only on-chip Intel device, but the above command reveals the detail, also telling me that my Mac is equipped with the AMD Radeon HD 6750M which is OpenCL 1.1 ...

I'm using iStat Monitor, which is a really great app. GPU monitoring is also supported. Here i found YouTube Review (not related with me, have further searches for better/other reviews)

Your particular MacBook Pro (6,2) has documented GPU problems for some units: https://support.apple.com/kb/TS4088 http://reviews.cnet.com/8301-13727_7-57577329-263/os-x-10.8.3-forces-discrete-gpu-use-in-2010-macbook-pros/ Even if you think you are out of warranty coverage, a call to Apple would be a good move. You've done most of the troubleshooting by ...

I am not saying you are wrong, but the GPU memory is normally used for rendering the current laptop 2D display, and then for the calculations for 3D display (games), and GPU acceleration (modern browsers). I've used, programmed various computers for many years, and yet to see an issue related to an application using to much GPU memory. But ISTRC MBP from ...

Try this ( http://blog.krzysztof-turek.com/apple-imac-8-1-freeze-problem-solution-en/ ) I had the same issues ; display frozen but pointer moving but no kernel panic on a mid 2007 imac 2.0 ghz and running osx 10.8 Mountain Lion. the kext swap worked for me . Good Luck

Some 2011 MBPs have a well-known GPU problem. So well-known, in fact, that Apple will replace your GPU for free! That link leads to Apple's page for their GPU replacement program.

I got into single user mode without much trickery, as my AMD card seems to work up to the point where the drivers are loaded, just with stripes across the screen. So I got to remove the drivers as described at asyncro. I rebuilt the kextcache (alternatively deleted it), but my Mac doesn't boot to internal graphics but uses the discrete graphics (according to ...

If it is a hardware issue, you'll have CPU usage and issues with a stock OS. Back things up and wipe it. Then run the iLife apps like garage band and iMovie and Photos to soak the CPU. Everything in my experience is you have some software issues that aren't ready for the new API and new CPU/GPU and will have occasional panics as the drivers get updated for ...

I'm using iStat Menus, which shows a GPU Memory Usage figure. The screenshot below is from my copy of iStat Menus 4.22. There is a new version 5 release, which includes "better per-app stats". I haven't tried this: I suspect it doesn't break down the GPU figures per-app, but it's worth a try -- there is a free trial.

I recently investigated the possibility of using the Macbook Retina as a CUDA development platform for scientific computing but came away disappointed with it's performance (as of Sep 22, 2014). I had purchased the more expensive model with the Nvidia graphics card for this specific purpose. See http://bit.ly/1vDxUbZ for details.

After a few arguments with a local Apple Store I contacted national Apple management and argued that the problems only started after upgrading to Maverick, which happened three years after purchase. Since they never mentioned Maverick would cause problems on a 2010 MacBook Pro the replacement program should still be applied. They finally agreed.

Thank you all I have used the linked procedure - http://www.asyncro.com/2014/03/24/macbook-pro-discreate-graphics-card-issue-fix-updated/ Although while rebuilding the drivers cache it has given me down the line "segmentation fault" but when it booted: I have noticed in Energy Saver "Automatic switching check box was removed now".Also My external video ...

BareFeats shows it outperforming other quad-core Macs in games testing. May not completely answer your question but that site is a good starting point.

This is the article you're looking for: The iMac and its 5K display... as a gaming machine? from ArsTechnica. Nevertheless R9 M9290X is one of the most powerful mobile GPUs on the planet. That should be pretty powerful on development workflows (I'm a UNIX dev too and do development on GPU, mostly for crunching numbers though). Edit: 280X was a typo, but I ...

My mid 2010 15 inch Mac Book Pro is in for a logic board replacement right now for what looks like the same issue. At least the first line of the log you posted is identical to the ones I was having. Apparently a run of nVidia graphics chips used in that vintage of 15 inch MBPs had a "latent defect". The bug can be tickled or not depending on the ...

Suggested problem tracing /and repair) steps (after each test the performances). Vacuum clean the inside of your Mac to improve cooling. Google and Install gfxCardStatus, Leave on Dynamic Switching. From there it will Monitor and Alert you to what apps switch you to the Nvidia Graphic Card. Also open the Activity monitor - Energy tab, where you can see ...
