ycode Posted July 21, 2016 Share Posted July 21, 2016 Hello everyone! I was stuck in a reboot loop when trying to install the latest El Capitan, so I decided to give macOS Sierra a try. However, I randomly get the message during boot up "error allocating xxx pages at xxx alloc type 2", with osxaptiofix2 (osxaptiofix never worked). And after booting up with nvda_drv=1, the screen always showed weirdly, but the system is fully functional, I can control it via my iMac with screen sharing. I searched through the forum for people using the same gtx 750 ti, but unfortunately, there seems to be none, and most reported working cards come with a 6 pin power connector, which may brick my card if I flash to any of those bios. Any help will be greatly appreciated! config.txt Link to comment Share on other sites More sharing options...
ycode Posted July 23, 2016 Author Share Posted July 23, 2016 The display issue still existed on different SMBIOS settings, or patches to AppleGraphicsDevicePolicy.kext . Later, I turned back to El Capitan, and I figured out that I didn't disable Super IO which caused the reboot loop issue. But, after installing Nvidia web drivers, the screen always turned black no matter how I changed the SMBIOS or AppleGraphicsDevicePolicy.kext , the situation seemed to be worse than macOS Sierra, so I installed it again. And still, I have no idea how to solve the 'error allocating pages' problem, it happens on booting of both OS (including installation). Link to comment Share on other sites More sharing options...
weezul Posted August 1, 2016 Share Posted August 1, 2016 I have a passive 750ti,(palit) no power connector just from the PCIe bus, and mine works fine once I installed the nvidia web os drivers. I got glitchy white screen before that though, but still useable to install the drivers Link to comment Share on other sites More sharing options...
