I just installed your app, and am at home, unable to test it fully. As far as I can tell, the app does permit power-source-based switching without the login display resolution problem! I have to test the effects on an external projector display next week when I'm in a classroom, however it may limit the resolution available to me when running on battery power and connecting a projector. This application allows me to choose the card to use when I want to save battery power and have no external display connected.īut it resets automatic switching if it was turned off before the app was run. This seems to be an Apple bug triggered by some update in the past couple of months, at least on my MBP. You can't get back the highest resolution and have black bars at the top and bottom of the screen (the higher resolution setting is not available on the integrated card, and for some reason the system won't permit the change). 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.On some Macs with dual cards, such as my 2011 MBP, use of the Energy Saver automatic graphics switching will trigger a display problem when logging out and logging back in: the display will be stuck on a lower-resolution option until restart. 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. Download gfxCardStatus v2. 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. gfxCardStatus is an unobtrusive menu bar app for OS X that allows MacBook Pro users to see which apps are affecting their battery life by using the more power-hungry graphics. 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.
