Guys, this is my first hackintosh, please don't be mad at me if I did something completely stupid. I NEED your help! I've been trying to boot into macOS for almost a week now. I've read Dortania's troubleshooting guide several times; visited every forum, looking for solution.

Setup
  • CPU: Intel Core i7-4770K
  • GPU: AMD Radeon RX 560
  • Motherboard: MSI B85M Pro-VD
BIOS
  • Fast Boot - disable
  • Secure Boot - disable
  • Serial/COM Port - disable
  • CFG Lock - disable
  • CSM - disable
  • Intel SGX - no option
  • Intel Platform Trust - no option
  • Parallel Port - no option
  • Above 4G decoding - no option (I have npci=0x2000)
  • VT-d - no option (I have DisableoMapper)
  • VT - enable
  • Hyper-Threading - enable
  • Execute Disable Bit - enable
  • EHCI/XHCI Hand-off - enable
  • DVMT Pre-Allocated: 128MB (can't be changed to 64MB)
  • SATA Mode: AHCI

Here is what I get:

23:346 00:020 AmiShimTimerBoostExit changed current period to 549254

I tried:
  • Disabling dGPU with -wegnoegpu
  • Patching iGPU
  • Changing platform-id
  • Installing different versions of macOS (10.14, 10.15, 11) (from App Store, USB made with createinstallmedia)
  • Turning off/on XhciPortLimit
  • Adding npci=0x2000 to boot-args
  • Turning on/off AppleXcpmCfgLock
Other (helpful) info:
  • OpenCore version: 0.8.0
  • SSDTs were generated with SSDTTime for windows
  • I used latest kexts and drivers
  • Monitor is connected directly to the dGPU via DVI cable

If you Google KASLR fix you should get a hit for the Dortania page with details.

Hi there.

As @P1LGRIM points out, some motherboards are more tricky than others to run macOS on. MSI and B85 together just makes things difficult, if not impossible.

I would try:

1) Disable the XhciPortLimit quirk.

2) Set the SecureBootModel to "Disabled" (You have set it to iMacPro1,1, nothing like the iMac15,1 system-definition you are using).

3) Disable the AudioDxe.efi UEFI Driver.

4) Remove or disguise any system serial-numbers in your configuration before zipping and uploading. You don't want anyone else pinching your data.

5) Let us know what storage you are using.

6) Disconnect any Windows drives attached while setting up.

7) The "KASLR" fix is "Slide=0" which ProvideCustomSlide should facilitate and you can add to the boot-arguments via NVRAM. There are other values apart from "0" but that needs much more research.

:)

Thank you for replying! I will try all of this soon and let you know if it worked.

Something I've already tried:
  • disconnecting windows drives does nothing
  • disabling AudioDxe.efi does nothing
I use usb 3.0 stick and plan to use SATA HDD for macOS installation.
