This program was working great as a workaround for the Logic Board graphics card issue on my 2010 Macbook Pro, until I upgraded to Mac OS Sierra.
When I was still using El Capitan, it allowed me to use the Integrated Only function, which prevented crashes due to the graphics card issue.
But now, in Sierra, when I try to use Integrated Only, I get an error message that I cannot use it, because several programs plus gfxCS itself are all on a dependencies list, which precludes integrated-only mode.
Currently, I can still use Discreet Only Mode, but it still periodically crashes (although less than with Dynamic Switching). Because of this, I am looking at possibly having to roll back to El Capitan, which the fascists at Apple do not make an easy task (backup required, El Capitan installer not available, etc.).
Has a solution to this problem been found? There are many Macs with this same graphics card issue, so I can't be the only one running into this problem. Please respond.
