derwolf Posted November 1, 2016 Share Posted November 1, 2016 I have a MacPro 4,1 flashed to 5,1 with a GTX 980Ti. It was working fine in Mavericks, but when I updated to Sierra I can't get the web driver to work. I just did the update so I have build 16B2657. I can get the latest 367.15.10.15f01 driver to install by editing my SystemVersion.plist to 16B2555. I revert back to 16B2657 after install and reboot. At first I get a message: "The default OS X Graphics Driver is now being used because the NVIDIA Web Driver 267.15.10.15f01 is not compatible with your current OS." I edited the Info.plist file in the NVDAStartupWeb.kext to activate the driver for my build which stops the message about the compatible version. However, when I attempt to change to the web driver using the Nvidia Utility and reboot it reverts back to the stock driver. When I run diagnostics on the kext file I get a code signing failure: MacPro:Extensions $ sudo kextutil -t NVDAStartupWeb.kextDiagnostics for /System/Library/Extensions/NVDAStartupWeb.kext:Code Signing Failure: code signature is invalidkext-dev-mode allowing invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext "/System/Library/Extensions/NVDAStartupWeb.kext"kext signature failure override allowing invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext "/System/Library/Extensions/NVDAStartupWeb.kext"Invalid signature -67030 for kext <OSKext 0x7fad1965cec0 [0x7fffb2505c30]> { URL = "file:///System/Library/Extensions/NVDAStartupWeb.kext/", ID = "com.nvidia.NVDAStartupWeb" } I had kext-dev-mode=1 enabled previously, but maybe it's not working in 10.12.1. I'm hoping somebody here can point me in the right direction of what to try next. Link to comment Share on other sites More sharing options...
