These are very quietI've been a Mac user for years, and I've repaired hundreds of different Macs, from the early II series to the latest 20 model MacBook Pros, iMacs (and other Apple hardware to boot!), and there is almost never a hardware situation where I've thrown in the towel and told someone to ditch their Mac.MacBook Pro 2.26GHz Intel Core 2 Duo (13-inch DDR3) MB990LL/A Mid-2009. Dispatched with Royal Mail 2nd class.
Buy Ram Late 2011 Upgrade For MacBookI've handled three 2011 MacBook Pros (none of them my own—I had an Air back then), and all three of them were scrapped because of the GPU issue.It doesn’t matter whether you want the best ram upgrade for MacBook Pro mid 2012 models or the best ram for MacBook Pro 2011 models, because there are options on this list for everyone. The problem was so rampant, Apple was forced to set up a free repair program for affected MacBook Pros—though the 2011 model has since been dropped from that program. There was a major flaw in the AMD Radeon GPUs included with that model year's logic board which seemed to cause GPU failure either due to overheating, internal chip problems, BGA solder joints getting broken, or a combination of the above. 16GB (8GB x 2) 79.99.The 2011 MacBook Pro has, for almost a decade, been the exception to that rule. Send us your old memory when you upgrade and we'll give you a rebate Recommended Upgrades. MacBook Pro 2.2GHz Intel Quad-Core i7 (15-inch DDR3) Late-2011.Memory trade-in rebate. Things I had seen before.Purchase NEW A1708 SSD Adapter NVMe PCI Express PCIE To M2 NGFF SSD Adapter Card M. Horizontal banding, some weird color issues. But then, I noticed the display would 'glitch'. First off, it was using a slow 5200 RPM hard disk after replacing that with a nice, fast SSD, and ensuring she had 8 GB of RAM in the laptop, I was pretty pleased with my work, and was about to shut down the laptop and send it on its way. Huh—usually the GPU issue would present itself during the AHT, but not this time.So I rebooted. So I ran the full (super long) test. I ran the quick test, which found no errors. Vizio smartcast app for macInternet Recovery mode (hold down Option + Command + R from startup sound to Apple logo)—same thing, again.Getting nervous, I then tried single-user mode (hold down Command + S from startup sound until you see the matrix text going past as the Mac boots into its FreeBSD underpinnings)—and was happy to find at least this worked fine. Recovery mode (hold down Command + R from startup sound to Apple logo)—same thing, again. Safe mode (hold down Shift from startup sound through to login or desktop)—same thing, stuck on grey screen after Apple logo + progress bar. Ten minutes later, still a grey screen—and the fans are spinning madly. Kext files (Kernel Extensions) are loaded. I didn't see anything obviously wrong, but knowing from past experience that problems usually surface only when the GPU/Radeon. A few records were off, but they were repaired successfully. The only thing that seemed wrong was the Radeon GPU. Single user mode proved disk, RAM, CPU, and even integrated graphics were okay. But then I thought twice—I would look if there was any possible way to resurrect this thing.Obviously everything else was working fine—Internet Recovery proved wifi/networking was okay. Better than telling my sister to junk the laptop! Hardware hack to cut off the GPU entirelyI'm not going to rehash the entire article from RealMacMods (after all, they found the process, and they also offer it as a service for $85 for anyone not willing or able to do it himself!), but I did want to highlight a few parts where I think it's important to further illustrate what needs to happen.The first part of the process involves prepping the software side of the Mac by doing the following: But then I scrolled further in that Stack Exchange answer, and noticed a link to this interesting article: MacBook 2011 Radeon GPU Disable - Real Radeongate Solution.Being somewhat handy with a soldering iron (but having never done SMD work—basically, soldering little bits and bobs that are the size of a speck of dust!), I thought I'd give it a go. But this time it would reboot itself within a minute or so, so that was different! Alas, after hacking around a bit more with System Integrity Protection disabled, the reboot cycle eventually became quite short indeed:Hitting dead ends when attempting the software fix, I was about ready to throw in the towel. KextsThat answer had a fairly comprehensive guide to—using software changes only—disable the Radeon GPU and get the Mac happy again.After running through the guide twice, I eventually got the Mac to boot. Attempting to drop the Radeon. Hack your EFI by adding a file telling your Mac to disable the Radeon GPU. Follow the directions to get in the right Arch Linux boot mode so you get to the console. Boot the MacBook Pro from said USB drive (hold option key at startup to choose it). (I use a cutting mat on my workbench. Unplug the Mac, put it on a nice, non-scratching, non-static surface, and flip it over. Shut down using the Apple Menu > Shut Down option.Again, see the source article from RealMacMods for the gory details (they even offer a $10 download to package up the fix for you—well worth it if you're not used to a command line!).Once that's done, it's time to get your hands dirty, by permanently modifying the MacBook Pro's logic board!First, to prepare the patient for surgery: ![]() Set down the iron / put it in it's holder, and get the resistor off the logic board. Just enough to not join the two pads together. If there are, heat the pads with the iron tip until you can 'wick away' the solder a little. Make sure there's not a solder joint between the two pads where the resistor used to be. And if you're like me, you might shoot the little resistor a few inches across the logic board! Just be sure to do the following after it comes off: Once that happens (after about 15 seconds in my case), put the tip against the side of the resistor facing the open space on the logic board, and push, with a very slight upward (away from the logic board) force.You might need to keep heating the resistor a bit before it pops free. The resistor is small enough I can't pick it up with my fingers—or even a standard needle-nose pliers!With the resistor gone, one step remains: replace the bottom cover, plug it in, and turn it on!I did so, and less than 40 seconds later (the SSD makes the boot process fast!), the Mac was as good as it's ever been, sans AMD Radeon GPU:One last thread that was worth a read-through for more background and debugging information was from the RealMacMods forum, After GPU repair issues (R8911 removal). And realize there are thousands of these things soldered to the logic board!Those are specks of dust in the image—except for the very-slightly-larger black spec next to the standard through-hole resistor. Take a second and marvel at it's minute size. I've just performed this mod, both the EFI mod and hardware resistor removal and I was amazed to discover it worked! I figured I've got nothing to lose and everything to gain - now my AMD chip doesn't appear in the list exactly as described, and it boots way quicker too.One thing I would say when removing the resistor - that thing is so damned small and I was worried I was going to damage nearby components by trying to get this tiny thing off. And, as suggested by RMM, try to avoid resetting the NVRAM, just in case that makes things go a bit south.I have a late 2011 17 inch Macbook Pro, and have had the logic board replaced once already (under Apples extended program) although that expired in December 2016, and the problem with the AMD chip reoccured just a couple of days ago! This is such a fantastic laptop and I have no reason to upgrade it as it performs fantastically with an SSD and 16GB ram.
