On Mac OS X Sierra, igetter initializes the discrete GPU when application is luanched.

Likely the NSSupportsAutomaticGraphicsSwitching value needs to be set correctly. I just updated to the 2.9.5 but it still has the same problem.

The following link might be helpful to fix the app:

You can use gfxcardstatus or activity monitor to show this.

Since no one ever reported such problem, we will investigate it and add the required key in iGetter Info.plist. If you have posted this a day before v2.9.5 release, it would have been already included.

Currently, we can't test iGetter on a dual-GPU MacBook Pro, so if someone is willing to test it, please contact us at .

It seems that Activity Monitor has an additional "Requires High Perf GPU" column in the Energy pane, which is missing on other Macs with a single GPU:

Update [06/26/2018] - iGetter v2.9.6 includes a fix for this problem.

I can also confirm that I am experiencing the same problem on my MacBook Pro.
I would be willing to test any fixes you may have.

Here is a quick fix for this problem. Open Terminal app (/Applications/Utilities folder) and paste the following one line command (then press Return):

defaults write "/Applications/iGetter 2.9.5/iGetter.app/Contents/Info.plist" "NSSupportsAutomaticGraphicsSwitching" -bool true

This command points to iGetter v2.9.5 in "Applications" folder. If your system is not in English or iGetter location is different, then you need to write the path of iGetter installation.

Note that Apple doesn't support automatic graphics switching with NSSupportsAutomaticGraphicsSwitching key on 2010 MBPs, so this fix should work on dual-GPU MacBook Pro models released after Early 2011.

That has cured the graphics switching for me. Thanks.
