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. ...

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 ...

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.

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 ...

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 ...

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 ...

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 ...

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 ...

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.

Lets start with this from Intel. Then go here and select the right driver. 🐶 EDIT: Since we still have the problem lets go back to BASICS: What do I need to install Windows 7? This table shows the required Bootcamp version. Try removing application receipts: If you're reinstalling an application or updating an existing one, try removing the ...

That screen indicates a likely graphics card or video RAM (GPU/VRAM) failure and not a software failure. These parts are one with the logic board, so it could also be the CPU. In any event, as long as you seek Apple for repair and the mac is less than 5 years old, it might be as little as $350 to fix if it needs a repair. You will want to back things up and ...

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 ...

The Intel HD 3000 was used as single card also in some Mac Mini configurations.

The solution for that kind of problem is to shut down the graphical windows management and to use Mac OS from a TTY. This is cumbersome, but not as much as to dual-boot your machine and to switch from one OS to the other. The way to do that is to go into Settings->Users and to set the login options to "username and passwords" (default is user list). Then ...

Instead of resenting the SMC (a painful procedure) try this free software. gfxCardStatus It is an unobtrusive menu bar app for OS X that allows MacBook Pro users to see which apps are affecting their battery life by using the more power-hungry graphics and Manually switch to Integrated Only or Discrete Only mode to force one GPU on or the other. Since I ...

There's some misinformation going on at the moment on what exactly is needed for Macs to support AirPlay Mirroring. The cultofmac article correctly states direct access to the GPU for H264 encoding but this is supported on Macs older than the one's listed to support AirPlay Mirroring. So this isn't the main requirement. The really important feature to make ...

I don't think you'll be able to do this. I tried RHEL and it locked up on load. Same results on Fedora 16. I did successfully install Fedora 17 but was unable to get dynamic video card switching to work. Nor was I able to get the Nvidia card to work. I believe you have to run dual X servers and map the second card to your DFP out based on other posts. ...

Apple's own apps on OSX has video acceleration support for years, provided by the GPU. h.264 hardware video acceleration is available to 3rd-party apps via the Video Decode Acceleration Framework since OSX 10.6.3. See: http://developer.apple.com/library/mac/#technotes/tn2267/_index.html ...

You can pass the CMAKE_INSTALL_PREFIX option to cmake to have OpenCV install to a different location. It's analagous to ./configure --prefix. For example: cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/opt/reallylocal -D WITH_CUDA .. This will install it under /opt/reallylocal, leaving /usr/local untouched. Then, to run your custom build, call ...

Since people are still commenting on this, I will post what happened as my answer: I took the MBP to a different store where they concluded that it was a faulty HDD cable since I had installed the SSD myself and they assumed it got some kind of shock for me not wearing an ESD bracelet. (Although as far as I can remember, the friend of mine who installed the ...

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). Some applications will force use the Nvidia card (without automatic switching).

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.
