[h=2]EGPU recognized only when external monitor is set as primary[/h] Hey tech inferno. I have been having a lot of trouble with my gtx 760/sonnet SEL/13" late 2013 rMBP. I have successfully gotten it to work on windows 10 using the optimus script. On OSX10.10.1 it only works when i have an external monitor set as primary. When i go to about this mac with the external monitor as primary, it shows my gtx 760. But when i set my internal monitor as primary, it says it is set on IntelIris. What do I need to do? Thanks
