The Tiresias solves this problem! Mac OS X 10.13 High Sierra (and later) is supported by the Tiresias! To have brightness control in High Sierra or later requires soldering two extra wires from the Tiresias to the motherboard. The problem in the use of nvidia is not the gpu, but the stabilization of the voltage when the gpu changes from g-state 2 to 0 (or 2 to 1), causing the known issues. I discovered that this problem happens every time that g-state change between 2 to 0 (or 2 to 1).

Apple issued a repair program, but the odds are that your GPU will die again soon. I have the famous MacBook Pro 6,2 with GT330m (0x0a29 model). The problem begins by seeing red lines on the monitor and then failing to boot OS X. Depending on what internal contacts in the GPU are ruptured this might confuse or even crash the Mac.Īny solution for disabling the GPU (also GMUX flashing or GMUX hard-wireing) will provoke High Sierra (and later) to not offer backlight control, and worse, to have the backlight off after sleep so it looks like the Mac does not wake from sleep. The 8.2 macbook pro models with integrated graphics card have a manufacturing issue that causes the lead-free solder of the GPU to crack, inhibiting its ability to function. Removing R8911 also prevents the Mac from getting confused by the dead GPU because even with the GPU turned off it will still try to talk to the dead GPU. This saves energy, generating less heat and conserving battery life. Other than that R8911 should be removed to turn off power to the dead GPU. An experienced technician can do this in minutes. You will need to mount a very small board onto the motherboard. How permanent is the GPU defect in 2011-2013 MacBook Pros Suppose one tests a used Macbook Pro by running a few random programs for ten minutes. This makes this the ideal solution to bring a 820-2914 or 820-2915 with dead GPU back to life. If the user clears the NVRAM (PRAM) there is no problem as the Tiresias will write the record again, and the Mac will work again. The Tiresias writes the 'gpu-power-prefs' nvram-variable to the ROM so that the Mac does not use the (dead) external (discrete) AMD GPU anymore. It is the external GPU that fails in 'a small percentage of MacBook Pro systems' (Apple-speak for: 'very many'). The internal (Intel) GPU that is part of the PCH, and an external (discrete) AMD GPU. This proves that our solution to the gpu trouble is a five star fix for this model. By adding 16 gb RAM and an SSD drive makes it even better machine. If for some reason you can’t visit an Apple store or dealer, follow the steps below to help resolve this issue.įirst, unscrew the cover casing by removing the 12 screws holding the back casing.The Tiresias is a small board that can be soldered onto the motherboard of the MacBook Pro 15-inch or 17-inch 2011 (Early or Late) models. After our fix to the 15 inch MacBook Pro, the machine still will have the same performance and power as mentioned for the above 13 MacBook Pro. If you still have your warranty intact, it is a good idea to visit an Apple store or an authorized dealer for repairs.
These are all symptoms of a graphics card issue.
