The only way to make sure you’re using the integrated GPU is to quit applications that rely on the discrete GPU, since OS X doesn’t let you choose to stick to the latter. So even if you’re working from battery power and trying to minimize battery usage (by turning down screen brightness, for example), you may still be using discrete-graphics-card cycles-and, thus, more energy. The problem is, some applications you wouldn’t think need a lot of graphics power actually rely on features such as OS X’s Core Animation that require the discrete graphics card. If the graphics cards are getting hot and failing is that due to crappy graphics cards or could something else within the system be causing the graphics cards to fail? How does this work? Best advice? I feel like Polly Purebread singing "Wonder dog, oh wonder dog! Where is my wonder dog?" Dating myself but this is a safe place where we can all share our feelings.Some quick background: All 15-inch and 17-inch MacBook Pro models from 2010 and later, as well as 20 models outfitted with an Nvidia GeForce 9400M/9600M GT, dynamically switch between a low-power (and lower-performance) integrated Intel graphics chip and a power-hungrier (and better-performance) discrete Nvidia or AMD graphics card, based on the needs of running applications. I don't want engine parts blowing out my tailpipe.Īll of that to say that I am not a computer savy lady and I need some clarity. If my system is old would putting a power hungry graphics card be the thing that sends it over the edge? An apple tech suggested that it would be like putting a turbo charger on a model T: it would work but engine parts might blow out the tailpipe. The thing that scares me is this card needs two six pin to eight pin adapter. I can upgrade to a Saphire Radion 580 which has two fans and good reviews. I know how this movie ends and it doesn't end nicely. Now I am getting the shut down and beeping UPS in the middle of the night. So that graphics card was replaced with another graphics card that was used/refurbished. I also noticed that there was a lot of heat coming out the back of the Mac. I called a repair guy and he said that it was the graphics card failing. This would only occur every few weeks.įinally in November I got weird squiggles on the screen. Odd that this only happened when it had been in sleep mode and always sometime during the night. The UPS manufacturer support article said that this occurs when something in the computer gets too hot. So I had him install a new graphics card (Nvidia Quadro) and replace the burned out board.Īfter about five months I would randomly find the Mac Pro shut down, and sometimes the UPS would be beeping. Worse yet (the repairman told me) it shunted the power to some board in my beloved Mac Pro and burned that out. It does everything I want and has more power that I need.Įarlier this year the graphics card finally gave up the ghost and failed. Mac Pro (mid 2010) graphics cards keep failing I have a Mac Pro (mid 2010) that I have bought new in 2012. Just wondering if anyone had any experience with the app and if I'm doing something wrong? Or will it not force apps that are designed to use the discrete gpu to use the integrated gpu? Perhaps my only way around this is to not use those apps and find alternatives. It was my understanding that it should force any app to use the integrated gpu but apps that need the discrete gpu are still using it, like Chrome and Photos. I downloaded gfxcardstatus 2.4.4i (running High Sierra 10.3.3) and set it to use integrated only. It's a great computer and runs fine when it's up. They referred me to an authorized repair center but $ is tight, so I'm looking for alternatives. They won't repair it because it's vintage. I have to reset the pram, smc, try to go into internet recovery mode, etc. Whenever an app needs the discrete video card, it will reboot. Long story short, my 2011 macbook pro has the dreaded logic board issue.
