How to Install Hackintosh macOS High Sierra on Intel Core i7 8700K

You would need a working Mac Operating system to perform this step. If you do not have access to working MAC operating system you can follow this guide.
How to Create Bootable macOS High Sierra USB Drive on Windows Operating System.
For those who already have access to working Mac Operating System, can continue with these steps.

Follow these Steps to Format You USB Drive.

1. Plug in your 16 GB USB Drive

2. Open Disk Utility and Select your USB Drive.
3. Click Erase and for the Name (Choose any Name of your Choice), for Format choose Mac OS Extended (Journaled) and finally for schema choose GUID Partition Map and Click Erase.
4. Once Erased click Done and close Disk Utility.
5. Now Open Unibeast and Click Continue for Introduction and Read Me.

6. Review the License agreement and click Continue.

For Destination Select, choose the bootable USB drive you just created and click Continue.

For installation type select High Sierra.
For the Bootloader Configuration select UEFI Boot Mode, if you have the latest Motherboard Asus Prime Z370P as recommended in the compatible part section. If UEFI is not supported on your Motherboard choose Legacy Boot Mode.
For Graphics Configuration select Inject ATI if you have Dedicated GPU on your motherboard. For this tutorial I have not selected any option here, as I will install Nvidia Graphics Drivers manually later.
Verify your installation options and click Continue.
Unibeast will ask you for permission, enter your password and click OK.
Now wait for 15- 45 minutes, until the Process of Copying files to USB is created. I recommend go make yourself some Coffee.
Copying Setup Files to USB Drive

Open the EFI partition on the USB Drive and go to the EFI folder.

Open the Clover Folder and then open the config.plist file. (Double click on the file to open it or right Click and Open with Clover Configurator.) If you have not yet installed Clover Configurator, download and install Clover.

Your Mac will warn you before opening the file, don’t worry. Click Open.

When Clover opens the config.plist file, go to SMBIOS option and click on the Magic wand icon. You will see the following options with different Apple products. Click on the option as per your required system specification. In this case I am choosing iMac Option.

Save the cofig.plist file and close Clover Configurator.

Now copy the Working EFI folder (download it from download section), Multibeast, Clover Configurator and Unibeast to your Flash drive.

Copy any additional Drivers or Software that you may need after Installing High Sierra Hackintosh on your SSD. Here you can copy the NVidia Web Drivers, your Wi-Fi Card Drivers (Mac OS should automatically detect the recommended AC1900 Wi-Fi card and you don’t need to install any drivers. If you are using external Wi-Fi card, copy the Wi-Fi card drivers to flash drive.)

Now, another important step here is to open your USB Drive and right click on the Install macOS High Sierra installer and Show Package contents.

Open the Contents Folder and delete the version.plist file from installer.

That’s it, we are done with creating our Flash Drive. Now you can eject the Flash Drive.

First you need to Insert the USB installer’ into the USB 2.0 Port and Start your PC. The USB 2.0 port is recommended because in some cases the USB 3.0 Port may not work during installation process. If the USB 3.0 port is working, then feel free to use it. (Give it a try)

Now during the PC is starting up keep pressing the BIOS or UEFI Menu button to access the BIOS or UEFI Menu.  For most Motherboards, the BIOS or UEFI Menu is placed on the DELETE button on the keyboard. (Please note your BIOS interface would look different but the options will be same in most cases)

Now when in your BIOS or UEFI Menu, first you will need to make a few changes.

1. First and Foremost, go over to the Advanced Mode(F7) Tab located at the bottom and  then go to the Exit Tab.

 2. Load Optimize Defaults that’s the first thing we want to do.
 3. Go to Advanced Tab and click on CPU Configuration\CPI – Power Management Control and then set CFG Lock  to Disabled.
4. Go to Advanced Tab and click on System Agent (SA) Configuration and then set VT-d  to Disabled.
5. Go to Boot Tab and make sure under Boot Option Priorities you have selected the USB that you just created to install Hackintosh macOS High Sierra on i7 8700k with ASUS Prime Z370. (Your USB name may be different , based on the Manufacturer or Brand). 

6. Now go to EXIT and click on Save Changes & Exit. When the confirmation popup appears click OK.
Now your System Will Reboot and the System will directly boot into the USB Drive. Incase you get the option to Select your boot drive, just Select the plugged-in Flash Drive.
Thats it for BIOS setting, when installing Hackintosh macOS High Sierra on Intel Core i7 8700K and ASUS Prime Z370.

Ok,When you select to boot from Flash Drive, you should see the Clover Boot Manager Screen. On this screen you will choose External drive (Flash Drive) Boot OS X Install from Install macOS High Sierra and press Enter to boot into the Installer.

First inside the macOS High Sierra installer select your language and click on arrow to Continue.  My preferred language is English.

Now the macOS High Sierra will take you to the macOS High Sierra utilities menu.

First before installing the macOS High Sierra you will need to Erase your disk. Select the Disk Utility and Press the Continue Button.

Now in Disk Utility select the disk were you going to install the macOS High Sierra Hackintosh and go to the Erase Tab.

For disk Name you can use any name and format you can choose between Mac OS Extended Journaled or APFS (Apple File System).

Note: If you are using newer, hardware then you can choose APFS but also, can use Mac OS Extended Journaled. If you are using legacy hardware or older hardware, then it’s recommended to use the Mac OS Extended Journaled.

Okay now let’s move on the post installation process. After you Boot in Mac OS High Sierra, you would need to copy all the post Installation files from the USB on the desktop. Also, after you copy the post installation files on desktop, you can eject the USB and remove the USB from the PC.

First, you’ll need to run the Multibeast application. Using Multibeast you will need to install the Boot loader and other basic drivers.

Now in Multibeast first select the Bootloaders. If your system is UEFI then select the Clover UEFI Boot Mode + Emulated NVRAM. If your system is legacy or some older PC then use the Clover Legacy Boot Mode. Please note to Install Hackintosh macOS High Sierra on Intel Pentium CPU you must select this option.

Now, under the Drivers Tab select the Drivers for your Audio Chipset on the motherboard. Select VoodooHDA v2. 9.0d10.
You don’t need to touch anything on Disk.
Under the Misc Select FakeSMC if it is not already checked.
 Under Network Select Your Internet LAN Driver
Under USB you can select the USB Drivers. I am going to select 3rd Part USB 3.0.
Now, go over to Customize and go to Graphics Configuration. Select NVIDIA Web Drivers Boot Flag.

Now, go ahead and Restart your Hackintosh. During reboot keep pressing the Boot Menu button to access in the boot menu. In the most of cases the boot menu button is placed on the F12 button on the keyboard. One more time we would need to Boot from the USB.

You will see Clover Boot Loader Screen. On this screen choose the option to Boot macOS from Macintosh HD and hit ENTER.

Enter your password and Log in. You will see some flickering, but don’t worry. This is caused as we have not yet installed the Graphics Driver.

We can now continue with installing the other drivers. If you are a Nvidia Maxwell  or Pascal user then you will need to install the Nvidia Graphic Web driver for Mac. After installing the Nvidia Web Drivers you can Restart your Hackintosh. (Note: When installing, Make sure the Destination you install Graphic Drivers on, is your Macintosh HD and not the USB. Also, before Restarting Eject your USB from your PC.)

If you have some additional drivers, then feel free to install the drivers. For example, Install the USB Wi-Fi drivers if you are using USB Wi-Fi Plug.

After installing all drivers, you can Restart your Hackintosh. In macOS High Sierra you’ll need to enable the Audio. To enable the Audio, go into the System Preferences and select Sound.

In Sound, under Sound Effects select Internal Speakers or in some cases Line Out.

Under Output select Internal Speakers or Line Out in some cases.

Under Input select your Microphone and finally the Mac OS High Sierra is ready to use.

Now you can continue with installing your favorite apps and software’s. You can also do your personal customization and you can enjoy all features of macOS High Sierra.
