[QUOTE="Nefos, post: 1687673, member: 361832"] Hi guys This thread will be about the Kernel Panics in 2010 Macbook pro models with GT330m. A little story about myself: I am coming from a PC and Electronic Engineering background, and hopped in to Macbooks as a hobby. I bought a 2010 Macbook Pro with GT330m and I saw these Kernel Panics.Tried to look online for some solution, but all I have received were 'bring it to Apple or buy a new one' and this is not an answer about actually what is happening. I tried to stress the laptop with 3D video game, no problem at all. But i found some errors popping up at random browsing. So i have done some work. Whenever you have these errors you will see the report, GPU panics and so on. But there is a really important line : P2/4\n"@/SourceCache/AppleGraphicsControl/AppleGraphicsControl-3.7.21/src/Apple MuxControl/kext/GPUPanic.cpp:127 it has tons of useless information but one thing caught my eyes: Apple MuxControl What is a Mux? Mux is a device called MUltipleXer, and it is there to switch between 2 signals and it is used by Apple to switch between the graphics cards So now we know that the Graphics cards have no problems, it is not a GPU problem, but a problem that affects the GPU, as the problem relies in the switching process But what causes the problem? I have downloaded Firefox, because it is a solid browser to test on. What I found that the Macbook restarts at Googles Chrome site in Safari, so I tried the same on Firefox. This time around I got way more information. The browser was shut down and complaining about OpenGL That would make sense, as OpenGL is used to make animations and Chromes site is starting with an animation I was checking some other websites with OpenGL animation but it was crashed randomly with the OpenGL error. So I am at the conclusion now. The problem lies in the software side, as the switching code cannot handle several OpenGL code or version stable enough so the switching process is not perfect, hence the computer getting confused. Can it be fixes by hardware or software means? I am not sure yet, I will need to do some research! UPDATE: [url]http://www.notebookcheck.net/Review-Apple-MacBook-Pro-17-inch-2010-04-Notebook.32424.0.html[/url] As mentioned at around the middle of the post, the error lies at the switching but they reckon it is because of the Intel OpenGL drivers [/QUOTE]
