Gfxcardstatus v2.2.1 2010 code#

And I once had Logic throw an error from one Even the Apple tech who came to replace it said he had never heard This happen to me, I once fried a wifi card by unplugging an external You may not believe me but I've had tons of stuff like Major company does it in some aspect, no product is perfect so how can youīenefit from it. Then make money on both ends, not sure if they would do that, but every Situation and can use the guise of an operating system to cause the issue. Its not out of the realm of possibility that they knew of a faulty Thousands of other users who have experienced this same thing, I view it asĪ Yosemite problem that triggers this problem. Byĭeduction, the only out of color variable is Yosemite. Risk it, went to Mavericks, and now everything goes to hell again. To Lion, worked back to Mountain Lion, everything was great. The internet recovery made me get Yosemite. After that, everything broke, even the app wouldn't let meĬhange the function of the graphics card again. It failed after it said it was switching to dynamic mode with thisĪpplication. Tried two different HDs already, one SSD and one factory Apple 750GB HD. One point I had Yosemite working for about 6 hours then it failed.

Went to Yosemite and tried to even do a bunch of tabs, it would act odd. Snow Leopard, Lion, Mountain Lion and Mavericks, all with success. I pushed my computer to the limit with each operating system This before with any Apple product I've ever owned and I started on theĪpple IIc. So, based on my testing, it seems that it would be a good idea to merge pull request into the gfxCardStatus master.Īfter Yosemite, everything went south. The existing check that refuses to switch to integrated only mode when an application is using the discrete GPU continues to function as it should with patch.

Most importantly, I also found that build never produced the situation where both GPU's would end up running at once.

None of the permutations I tried resulted in bad behaviour.

I tried to get the build to switch to the wrong configuration by selecting various modes while launching and quitting different combinations of applications that normally prompt the discrete GPU to activate.

Then I tried to see if I could find ways to make build perform the wrong behaviour. It passed them all.įirst, I tested it in situations that triggered the bug when using the standard build, and build handled them all excellently, every time. I put it through various tests to make sure that it did what it is supposed to do, and that it did not do anything it shouldn't do. Sorry, something went version seems to work perfectly. I think a better solution would be to first select Dynamic Switching to ensure the smoothness, then change it immediately afterwards to the user's last selected preference.

Do note that forceSwitch doesn't help in this case, since it resolves any discrepancy to the system mode, while my solution resolves it to the user's preference, which is how it should be.ītw, I have also read that you have selected Dynamic Switching to default upon login so that the app runs smoothly.

In the displa圜onfigurationCallback section in GSGPU.m, if the user has selected Integrated Only but the discrete graphics is on, there will be a call to to change it back to Integrated Only.

Created a static variable in GSMux to note which mode the user has selected.

The few lines of code I've added in fixes this problem: The problem is that the mode will change to Discrete Only after certain apps which use Core Graphics close, such as Chrome or iOS Simulator. I have been a fan of your app for a long time, using it to force the Integrated Only mode.
