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. 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. 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. 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. I eventually got things sorted out, but it meant being without my MacBook Pro for an additional week.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. When I got mine replaced, the service provider mistakenly replaced my 2.6 GHz CPU and logic board with a 2.5 GHz model. One more thing: if you do get your logic board replaced under this program, make sure the replacement board is the same model you brought in. MacBook Pros covered under this program were manufactured between approximately May 2007 and September 2008, have an NVIDIA 8600M GT graphics processor, and include: If you have one of the models listed below, and you've been experiencing graphics-related failures, take your MacBook Pro in and get it serviced - it shouldn't cost you a cent. Thankfully, my machine's weakest link is still serviceable at no cost to me for another year or so. I already had one logic board replaced last November thanks to a faulty NVIDIA GPU, and until a TUAW reader reminded me about the out-of-warranty service program's extension to four years, I was worried about the GPU failing again within a couple months of my AppleCare coverage lapsing. According to an enormous, 157-page thread on the Apple Support Communities, a number of early-2011 MacBook Pro owners began having problems with the AMD discrete graphics cards inside their laptops. The good news is that even though your AppleCare coverage may be expired, your GPU is still covered for another year.

My Early 2008 MacBook Pro's AppleCare expired last week, and many early adopters of the first MacBook Pro with a multi-touch trackpad will be in the same boat.

According to Apple, 'If the NVIDIA graphics processor in your MacBook Pro has failed, or fails within four years of the original date of purchase, a repair will be done free of charge, even if your MacBook Pro is out of warranty.' Apple's replacement program for the 8600M GT was initially valid for three years beyond your purchase date, whether you bought AppleCare for your Mac or not, but in 2010 the program was extended to four years from your purchase date. If you own a MacBook Pro with an NVIDIA GeForce 8600M GT GPU and an expired warranty, you may be unaware that since late 2008 Apple has offered a free out-of-warranty service program for the faulty graphics chipset.
