How this would be possible if a significant HW dies? Simply do not understand and out of ideas how to prove it. System can switch to it, gfxCardStatus works fine (no errors shown), the Apple HW test (even the extended one) shows 'no problems found', LuxMark allows to select nVidia card for testing, etc. Normally I would say the nVidia card just died, but nothing is showing this.

But I think it did not update GPU drivers and I am unable to find pure GPU drivers on nVidia site just to test it. Today I reinstalled these CUDA drivers again and again updated them to the latest version with still the same result. It suddenly stopped over night and I am not aware that I installed anything (not even any appliacation) during that time between the last time I know for sure it worked (Monday evening) and the time I discover it does not work (Tuesday evening). So it worked with these drivers for almost 2 weeks without problems. I installed CUDA drivers about 2 weeks back. Any way how to distinguish this rather than to rely on gfxCardStatus? Any log that would make this clear? Any test I can run (Apple HW test shows 'no problem detected')? Is there a way to see if the nVidia card is working? I suspect that even if the system is trying to switch to a discreet card it still runs on the Intel in reality. Only in heavy load it is obvious that it is slow (slower than it was). gfxCardStatus shows that the system switches the card and I notice no change. flickering or black screen when swithech do nVidia - nothing. But otherwise there is no visible flaw, e.g. But I tried to uninstall it and got the same result. Only one thing comes to my mind - Apple Java update. I do not remember installing something that day/night that could have broken it (in case it is a SW problem). I took another test and downloaded CINEBENCH to see the differences and sadly the results are the same if I switch to nVidia or to Intel and run the benchmark. But the performance is the same as running it on an internal Intel. I installed gfxCardStatus to see whether the card is being switched to run the game and it actually is. It took me several hours to find where the problem is and it seems to me that the nVidia dicrete card is not working. It ran fine till yeasterday when I fired up a game which was laggy and it was running fine before.

This page was generated by GitHub Pages.Having a MacBook Pro Retina. Requires macOS >= 10.12 gSwitch is maintained by CodySchrank. GPU control with apple is mostly guess work since there isn’t any documentation, so, If anyone finds anything let me know here! Notes However there could be other API’s that could work, I just can’t find any. It appears that apple has removed the necessary API’s from these macbooks on the modern macOS. This could potentially brick your computer LegacyĪt this time it seems like gSwitch will not work on macbooks older than 2011. entry use OS / Version / GFX Card / Status where status can be ok. Ok I lied you technically can but I DO NOT RECOMMEND IT. If your card manufacturer does not supply the OpenGL drivers or they are inadequate. gSwitch just switches back to the integrated one as fast as it can. However gSwitch cannot prevent your discrete gpu from being accessed by the operating system, and it will be accessed for a short period of time when a process requests the use of it. You can’t, your macbook was designed to use both, but gSwitch can trick it into using the integrated one most of the time. You cannot force integrated only if you have an external display plugged in.

You can force integrated only when you have dependent processes but it might crash those processes. If you change to dynamic switching or discrete only any process that was hungry will become dependent. A hungry process is one that wants to use the discrete gpu but is not allowed because you have set integrated only. What is a dependent process vs a hungry process?Ī dependent process is one that is currently using your discrete gpu. And since you plugged in the cable I’m assuming you want to use the display.

Unfortunately your mac is designed such that in order to use an external display, it has to use the discrete graphics card. Why does the app go back to dynamic switching when a display is plugged in? The current gpu is also reported in the menu. Otherwise, it will just look like a gear. The gear will have a dot in the middle when the discrete gpu is active.

You probably need to allow the application to run in Settings -> Security & Privacy

You can also launch it from the terminal and set the desired setting using -integrated, -discrete, and -dynamic. gfxCardStatus is a free tool that enables you to not only see whether your system is currently using the integrated or discrete GPU, but also gives you the chance to manually switch whenever you. You can also enable notifications for when your gpu changes (off by default) The app is simple to control with integrated only, discrete only, and dynamic switching in the menu.
