Hi folks I am trying to enable Optimus on my iMac, as of now i have the following : - Akitio Thunder 2 - EVGA GTX 1050 Ti SC - Windows 10 Home - booting the iMac with apple_set_os.efi, in order to have the Iris enabled so i can see On this setup, the driver (378.78, latest) is installed from nv_dispi.inf section 088, i checked and no NVSupportOptimus exists in that section. I searched in nvdmi.inf (because this is the only INF that has anything with GTX 1050 Ti ) and for my card i can only find these entries which none of them have Optimus enabled %NVIDIA_DEV.1C82.068B.1028% = Section277, PCI\VEN_10DE&DEV_1C82&SUBSYS_068B1028 %NVIDIA_DEV.1C82.0790.1028% = Section260, PCI\VEN_10DE&DEV_1C82&SUBSYS_07901028 %NVIDIA_DEV.1C82.079A.1028% = Section275, PCI\VEN_10DE&DEV_1C82&SUBSYS_079A1028 My device should be 1C82.6253.3842 However, connecting the same setup to my Macbook pro retina late 2013 works like a charm and Optimus is enabled, and surprise, the driver is loaded from the same nv_dispi.inf. Any ideas how to enable it on iMac ? Is there other check that gives result that iMac is not notebook platform and disables Optimus ? Thanks
