[Solved] Black Screen and Frozen with Nvidia web driver.

[louielo]

I have this issue after 2018-001 security update. before this update, my hackintash worked well. since that, I can not boot with my GTX960 (2GB), it always stops and be frozen when booting(after the attached image IMG_6753.jpg). but I can boot into system with "nv_disable=1" or remove my GTX960.

my system info:
macOS 10.13.4 (17E199)
Nvidia web driver: 387.10.10.10.30.106

I tried:

• install to L/E with KextBeast: lilu.kext (1.2.3) NvidiaGraphicsFixup.kext (1.2.6) and lilufriend.kext(1.1.0)
• put these kexts to EFI/EFI/Clover/Kexts/other and 10.13 folder: lilu.kext (1.2.3) NvidiaGraphicsFixup.kext (1.2.6)
• update Clover to v4439 and tried adding boot flag "nvda_drv=1"
• I tried to use: OsxAptioFix3Drv-64 / OsXAptioFix2Drv-64 + EmuVariableUefi-64,
  now I am using AptioMemoryFix, but still the same, black screen and frozen.
• I updated OSX to High Sierra 10.13.4 (17E199),
  (saw someone update to OSX 10.13 and fixed automatically, but I guess it's not for me.)
• I also update FakeSMC.kext(6.26-322-g1b20eab7.1765) USBInjectAll.kext (0.6.4)
• SMBOIS iMac 17,1
  I tried using iMax 14,2, but it did not work and changed back to iMac 17,1.

(I was so dumb that I didn't backup before security update..

Update 2018/5/2

if I remove NvidiaGraphicsFixup.kext, I can boot into desktop but it has "black screen" (the system is working, can use screen share, and has sound feedback)
but isn't the NvidiaGraphicsFixup.kext supposed to fix "black screen" issue..

[Solved]
i am using SMBOIS iMac 18,3 without NvidiaGraphicsFixup.kext.
the screen is magically back and working normally.

Thank you!

All these guides showing NvidiaGraphicsFixup.kext seem to be false, removing it and setting SMBIOS to iMac18,3 worked for me as well!
