Toleda analysed a bunch of IOREGs for us folks stuck with non-functioning GTX 750 Ti cards and he's ruled out any issue with the NVCAP or the framebuffers. The problem is mainly limited to ASUS cards, the ASUS Strix OC card with VBIOS 82.07.32.00.xx being the only exception which has even the HDMI port working. My hackintosh works fine with the on-board Intel HD 4600 (1536MB VRAM) graphics (Motherboard: Gigabyte GA-B85M-D3H, supported as per the HCL).įrom my extensive discussions on other forums, I have gathered that this problem is not faced by cards sold by other vendors such as Palit, Gigabyte, EVGA, MSI - if any problems have been faced by these cards, they have been solved/fixed. I have tried PCIRootUID=0, GraphisEnabler=No/Yes and all other sorts of boot flag permutations and combinations but NOTHING. I have tried PCIRootUID=1 as one of the bootflags, as suggested in other solved threads in this forum for the ASUS GTX 750 Ti, but I get the same result.
I have tried 3 different HDMI cables and even a DVI2HDMI adapter.Īpparently, VGA works on this card for a lot of people but I haven't been able to try it out. I get a blank screen with a 'No Signal' message on the HDMI and both the DVI ports with Yosemite, after the Apple logo boot screen or after NVIDIA Drivers have been loaded in verbose boot. While I have all ports functional in Windows and for my gaming needs, I'm not able to get any port to work with Yosemite. The card is installed correctly and is detected in System Report > Graphics/Displays and even in NVIDIA Driver Manager's ECC tab (of course, ECC not supported though). I have 1xHDMI and 1xVGA ports on my monitor Dell S2440L. I have 1xHDMI port, 2xDVI-D Dual Link and 1xVGA ports on the card. I have tried this card out on both Yosemite 10.10 and 10.10.1 with NVIDIA Web Drivers 343.01.01f01 through f03 and 343.02.01f01.
