Note: There are some problems installing the initial Nvidia drivers (378.10.10.10.15.114) for High Sierra (HS). This was my solution to the kext install error and resulting black screen. In my initial HS installation, I did not add any other graphics kexts (e.g. Lilu.kext, Shiki.kext, NVWebDriverLibValFix.kext, etc).
Note: If you have the black screen and can't get into your HS system, then boot into the Recovery system. Then, from the top menu: Utility > Terminal. In the Terminal, remove the Nvidia drivers with the following Terminal commands:
Code:
cd /Volumes/yourHSdiskname/System/Library/Extensions/
rm -R GeF*.*
cd /Volumes/yourHSdiskname/Library/Extensions/
rm -R GeF*.* NVDA*.*
cd /Volumes/yourHSdiskname/
sudo touch ./Library/Extensions/ ./System/Library/Extensions/
Reboot. For some reason, the above breaks audio. So, if you can get along without it while trying the below procedure, I'll tell you how to regain audio below.
Installation
I am testing High Sierra on my Gene system with a NVMe and (temporary) a GTX 1060 with the SysDef iMac14,2. HS was easy to install (over a GM installation), but when I went to install the Nvidia drivers...well, I experience the problems you all have had. So, benefiting from your efforts, I successfully installed the drivers doing the following:
Mount the HS drive's EFI partition and change the SIP setting (CsrActiveConfig) from MultiBeast's default 0x3 to 0x0 which turns on SIP and save;
Make sure that the Security and Privacy System Preference pane General tab setting for "Allow apps downloaded from:" is set to "App Store and identified developers";
Reboot;
Once back to the Desktop, open the Security and Privacy System Preference pane and make sure the General tab is showing;
Start the Nividia install process;
During the installation, a window with a message like "The [...] kext is not signed and, in the Security and Privacy System Preference pane, you can approve its installation" (or something like that);
Once you approved the installation of that kext, the installer will complete and ask to your click on the "Restart" button...Don't do it yet;
In the Terminal, "touch" the two major kext directories:
Code:
sudo touch /Library/Extensions/ /System/Library/Extensions/
Now, mount the EFI partition and change the SIP (CsrActiveConfig) setting back to 0x3 and NvidiaWeb setting to "true";
Reboot;
The update "breaks" audio, so download and run toleda's audio_cloverALC-130.sh script from:
GitHub - toleda/audio_CloverALC: OS X Realtek ALC onboard audio with Clover;
Reboot again.
You should be good to go!
Unfortunately, the GTX 1060 has worst glitching upon wake up from sleep then it did in Sierra. As a result, this problem caused me to reboot since the usual fixes couldn't be tried.
