![]() ![]() 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. So far, this seems to occur only after the initial load of a page and before the. ![]() I noticed that some websites in Safari (e.g., the new Apple Music site) cause the entire screen to flash black for a split second. gfxCardStatus is a menu bar application for OS X that allows MacBook Pro. This seems to be an Apple bug triggered by some update in the past couple of months, at least on my MBP. 2015 MacBook Pro 15' - Screen occasionally flashes black when using Safari. By more precisely controlling when each graphics card is enabled, users can improve system performance or battery life. 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).

The screen will go blue and then black, but will then reappear and the secondary GPU will be used. GFXCard Status is an open-source utility for OS X that displays which graphics card is currently being used on MacBook Pro (and the older iMac) by monitoring a console. While the program is built for the new Core i5 and Core i7 computers, I am able to run it just fine on a Core2 Duo system running the GeForce 9400M/9600M combination however, it is not supported and claims my system is running the GeForce 330M regardless of what GPU I have running.ĭespite this, the program does offer a unique advantage to users of the older MacBook Pro models, in that the GPU switching feature does allow for you to switch GPUs without logging out and closing down your applications. Once you isolate the process, you can isolate the application causing it to do so using Activity Monitor. In addition to notifications and alerts, gfxCardStatus will list any processes that are using the current graphics processor, and allow you to manually switch the active GPUs on the system. Before you do anything else at login, from its drop down menu, check the PID causing the system to switch to the discrete card. What's up with the MacBook APP GFXCARDSTATUS I installed it on one of the 2016 15' rMBP in one of the Apple Reaeller stores and even if I selected only integrated graphic card through the APP the. If you have the Growl notification system installed, gfxCardStatus will inform you in real-time whenever the graphics processor is changed. When the system's computing demands change and the GPU is switched, this utility will show the switches in real-time, either by displaying an "n" (GeForce 330M) or a "i" (Intel HD) in the menu. You can use that to control how integrated graphics is used. MacOS has a command line tool called pmset used to manage power saving settings. GfxCardStatus is a small menu extra that displays which graphics card is the active one. This question is pretty old, but in case somebody stumbles here from a Google search, I wanted to add another option if gfxcardstatus doesn't quite work for you. The menu extra allows you to quickly change GPUs without logging out, including on older MacBook Pro systems. This is convenient however, Apple does not provide an easy way to manage the different GPUs on the system, and if you like to tinker you may find the utility gfxCardStatus useful, both for newer and older machines. On Apple's latest MacBook Pro systems, the dual GPU setup allows for dynamic switching between the onboard and discrete graphics chips to optimize performance and battery life, depending on the tasks at hand. ![]()
