slurpi posted a topic in OSx86 10.13 (High Sierra)Sleep, USB 2.0 and USB 3.1 work after installation. USB3.0 needs post installation steps, although some ports are recognized. Audio also needs some post installation work. This is just a guide on how to install the OS. The post installation setup follows on a post below. Hardware: Motherboard: MSI X299 SLI Plus CPU: Intel i7 7820X RAM: 4x 8GB Corsair Vengeance DDR4 @ 3200MHz (32GB total, quad channel mode). Storage: Samsung EVO 960 M.2 250GB (for OS) Crucial MX300 1TB (for data) Network: WiFi TP-LINK Archer T9E AC1900 (PCI, supported by macOS) Bluetooth: Broadcom BCM20702 (USB, supported by macOS) Video: MSI GT 710 2GB (supported by macOS) Asus ROG Strix GTX1 070 8GB (needs NVIDIA Web Drivers) BIOS: I used version 140, the latest at the time. I am running version 150 now, with no differences. Disable "CFG Lock": Enter BIOS Load defaults (F6) Expert mode (F7) OC and then CPU Features (last item) Disable "CFG Lock". Save and reboot (F10) You have to disable CFG Lock, otherwise the kernel does not boot. The system restarts after "+++++" from Clover. In addition, I advise to disable legacy mode in the UEFI, to avoid booting in legacy mode and get confusing errors from Windows or Disk Utility. Clover installation on the USB: Install for UEFI booting only Install Clover in the ESP drivers64UEFI all selected (more on this below) all rest is off Clover drivers: When the Clover installation finishes, you have to manipulate a few efi drivers. Navigate to <USB ESP partition>/EFI/CLOVER Create a folder called drivers_disabled Move the following drivers from drivers64UEFI to drivers_disabled: OsxAptioFix2Drv-64.efi OsxLowMemFixDrv-64.efi You will have to add an extra driver from here: https://nickwoodhams.com/x99-hackintosh-osxaptiofixdrv-allocaterelocblock-error-update/ Download Test2-2016.efi and save it in drivers64UEFI. Without this fix, you'll have the memory allocation problems described in the link above. If you still get that problem, don't just reboot but really turn the computer off and then on between tries. I also had to install apfs.efi. Clover config.plist: I used Clover Configurator to load the default clover.plist and then: ACPI: disable everything. Boot: npci=0x2000. I also added -v. SMBIOS: iMac18,3 Any iMac18 should work (I tried with 18,1 and 18,3). I also tried with iMac14 and iMac17, and they gave me problems. For example, iMac17,1 could not initialize the graphic screen properly. Leave all the rest as default. Save. All these changes can also be done at the clover menu during boot. Note that I am not claiming this is the best configuration for a running machine. It is the simplest that allowed me to finished the installation and reboot successfully. I think it is possible to handle the efi Clover drivers installation using Clover Configurator, but I have never done that. Kexts: FakeSMC.kext. I used the one from Rehabman, but I think the official one will work as well. VoodooTSCSync.kext. This is mandatory, otherwise the system does not boot properly. It needs to be configured as follows: open VoodooTSCSync.kext/Contents/Info.plist and change the line under <key>IOCPUNumber</key> to: <integer>15</integer> This is the number of threads of your CPU minus 1. Place both kexts in EFI/CLOVER/kexts/Other. Video: I used the MSI GT 710 for installation and all post-installation steps. The 1070 only works with NVIDIA's Web drivers. Don't use it during installation. Check the post-installation post below to make it work. And this is it. Installation should work without a problem. Remember to use always the USB during the several installation reboots. I did not activate iCloud and my Apple account during installation. I wanted to generate a real fake machine UUID and serial number, so that I can use all the Apple services. This was done after installation, while booting from disk. What needs to be done during post-installation: Fix USB3. Fix audio. CPU ID recognition, although this might be fixed by Apple on a new iteration of the OS. Confirm that the CPU is working properly with all cores and different power states. Install NVIDI's Web Drivers for the Asus GTX 1070.
