![]() ![]() gfxCardStatus provides a lot of control over which card is in use at any given time, and can also just notify you when the system decides that you should be using a different graphics card, and shows you why exactly the switch was made (under "dependencies"). For example, Google Chrome and Skype, among many others. But it's not perfect, and a lot of apps will inadvertently force the system to use the better graphics card. the OS will switch to the better graphics card, and when you're done, it will switch back to save power. When you connect an external display, load something up in Flash, start a game, etc. Mac OS X automatically switches between the available graphics cards. Most 15"/17" MacBook Pros sold since 2009, if I remember correctly, have 2 graphics cards - one discrete card that is very powerful, but somewhat power-hungry, and an integrated one that is much less powerful but draws less power. well, now that you mention it, I guess it's only been about 2 years :) ![]() How many people have multiple graphics cards?Haha. GfxCardStatus is a free download from creator Cody Krieger's website. I simply didn't have the stamina to test that claim, but I did make one nine-hour run with OS X reporting a nine percent remaining battery capacity. Turning down screen brightness to just two "dots," a technique I often use to maximize battery life when using a MacBook Air during conferences, caused OS X to report potential battery life as high as 10 hours. I recently updated to 10.14.3, and when I open GFX it freezes in Activity Monitor and never opens. I was consistently able to get between 8 and 8.5 hours of continuous use from the Retina MacBook Pro when running integrated graphics only. GFXCardStatus not working 2018 MBP, 2.6GHz, 16GB Memory So I haven't used GFX in a while, but I came back to it recently because I was using my laptop on battery and it was stuck on using the GPU, so battery life was tanking. gfxCardStatus is a menu bar application for OS X that allows MacBook Pro owners to view which GPU is in use at a glance, and switch between them on-demand.Īrs Technica has much more, including the fact that the Retina MacBook Pro can be pushed to nearly 10 hours of battery life with some minor battery saving techniques: Testing is currently ongoing however initial results are promising (although this was the case while using the initial 2.2.1 version). By more precisely controlling when each graphics card is enabled, users can improve system performance or battery life. 2012-2013 MacBook Pro 15' Retina video issues WHAT IS WRONG AND HOW TO FIX CORRECTLY. Unfortunately, we were not using gfxCardStatus before the problems started affecting our testing machine, however we have downgraded to version 2.0 of gfxCardStatus to see if this helps resolve the issue. ![]() GfxCardStatus allows users to control which graphics card is enabled - integrated or discrete - on MacBook Pro models with multiple graphics cards. ![]()
