How to clean install macOS Sequoia on Hackintosh?
If you don't have macOS installed on your Windows computer or prefer a clean installation of macOS Sequoia, follow the steps below.
Step 1: Check your computer's processors
The first step is to check your PC's processor to learn the correct OpenCore EFI you'll need if it's Intel-based. But if it's an AMD processor, it's not necessary.
- Press Ctrl-Shift-Esc to open Task Manager.
- Select the Performance tab.
- Click on CPU.
- Check which generation of processor your PC has. For example, if it's i7-4790, it's the 4th generation (4790) called Haswell.
Step 2: Gather needed applications
Then, you need to prepare the files and tools required for the installation.
① Download the macOS Sequoia installer
There are two ways to download the macOS Sequoia installer. You can get it from the App Store by searching its name and following the onscreen instructions. Or download it directly from a third-party source.
② Get Balena Etcher, ProperTree, and others
To install macOS Sequoia on Hackintosh, you'll need the following tools:
- Balena Etcher: It's needed for creating the bootable macOS Sequoia installer.
- ProperTree: It's used to edit the config.plist file. (Open the link, click Code > Download ZIP.)
- Explorer++: It can delete the files in the EFI folder of your bootable media and allow you to transfer your customized EFI folder into it. (Get the 64-bit.)
- GenSMBIOS: It's for generating the compatible SMBIOS for your hardware.
- OpenCore Package: This is important for making the EFI folder. (Download the latest OpenCore package.)
- An external drive with at least 16GB of storage space, such as a USB stick or an SSD. (This drive will be erased during the process, so back it up beforehand.)
After downloading all the necessary apps, continue with the next step.
Step 3: Create a macOS Sequoia bootable Installer on Windows
In order to install macOS Sequoia, you must first create a Sequoia bootable installer on your PC. Here's how:
- Open Balena Etcher.
- Click "Flash from File."
- Select the macOS Sequoia installation file and click Open.
- Click "Select Target."
- Connect the external drive you prepared.
- Select it.
- Tap Flash to begin writing the macOS Sequoia files into the external drive.
Step 4: Build or download the OpenCore EFI folder
While the bootable drive is creating, you can start making the OpenCore EFI folder manually. Or, download a prebuilt one for your computer and decompress it. This is a crucial component for the OpenCore bootloader used in Hackintosh setups, which contains the necessary files and configurations to boot macOS on non-Apple hardware.
Here's how to create the OpenCore EFI folder from scratch:
Double-click the OpenCore Package file to extract it.
Open the OpenCore folder.
Head to X64, then copy the EFI folder and paste it into your Downloads folder or another one.
Go back to the OpenCore folder.
Open the Docs folder and copy the Sample.plist file.
Navigate to the EFI folder you copied before, open it, and paste the Sample.plist file to the OC folder.
Rename the file Sample.plist to config.plist. 
In the OC folder, open the Drivers folder.
Delete all drivers except for OpenCanopy.efi, OpenRuntime.efi, and ResetNvramEntry.efi. 
Download HfsPlus.efi and save it to this Drivers folder.
Customize the EFI/OC/Kexts folder based on your hardware.
Open this link in your browser, then download the release version of the "Must Have" kexts: Lilu and VirtualSMC.
Extract the VirtualSMC zip file, and add VirtualSMC.kext and other kexts needed for your hardware to the EFI/OC/Kexts folder based on the information on the link provided above.
Open the Lilu file and add Lilu.kext to the Kexts folder.
Continue to add necessary kexts for graphics, audio, and more. 
Open the EFI/OC/ACPI folder.
Open this page, select your hardware type and generation, and then download the associated files.
Paste the .aml files into the ACPI folder. 
Download the OcBinaryData folder.
Open it and copy the Resources folder to EFI/OC/Resources. 
Delete all files in the EFI/OC/Tools folder.
Now the EFI folder is ready.
Step 5: Customize the config.plist file
After the EFI folder is customized or ready, you need to modify the config.plist file to make sure that macOS Sequoia runs smoothly on Hackintosh.
- Run ProperTree.
- Click File > Open, navigate to the EFI/OC folder, then select the config.plist file and click Open.
- Tap File > OC Snapshot, then click "Select Folder."
- Delete the four warnings.
- Click File > Save to save the changes.
- Open this webpage, select your PC type from the left sidebar, and modify the config.plist file based on the information on your model.
- For instance, if the info specific to your computer model says ScanPolicy should be set to 0, you change the same parameter in the config.plist file to 0.
Step 6: Generate SMBIOS
Next, you must generate a compatible SMBIOS (System Management BIOS) to help macOS Sequoia recognize your hardware as a specific Apple model.
- Extract the Gen-SMBIOS zip file.
- Open the extracted folder and double-click to run GenSMBIOS (the Windows Batch File).
- Ensure you're connected to the internet.
- Enter 1 and hit Enter to install and update MacSerial.
- Enter 2 and hit Enter to select the config.plist file.
- Head to EFI/OC and then drag the config.plist file to the command-line window.
- Hit Enter.
- Choose the right SMBIOS for your hardware based on this guide.
- Type the compatible SMBIOS, for instance, MacPro7,1 then hit Enter.
- Enter Q and press Enter to quit the cmd.
Step 7: Create a partition for macOS Sequoia
With the required folders and files prepared, you can now head to make a partition specifically for the macOS Sequoia installation. To do this:
- In the search bar, type partition and then open "Create and format hard disk partitions."
- Decide where you want to install macOS Sequoia. If it's on your PC, you need to shrink the C drive and create a new volume; if it's an external drive, just reformat this external drive.
- To create the partition on your PC, right-click on the C drive and choose "Shrink Volume."
- Enter the amount of space you want to shrink in MB and click Shrink.
- Right-click on the new unallocated space and select "New Simple Volume."
- Follow the instructions and keep NTFS as the format.
- Name the partition macOS Sequoia or your preferred name.
- Format it.
Step 8: Prepare the EFI partition on the bootable installer
Before utilizing the macOS Sequoia bootable installer, you must replace the data on its EFI partition with the EFI folder you built earlier. To do this, you'll need to add a drive letter to the EFI partition with the help of Command Prompt or a tool like MiniTool Partition Wizard, then run Explore++ as an administrator to open the EFI partition, delete all its content and copy and paste the EFI folder to it.
Step 9: Install macOS Sequoia on Hackintosh
Finally, you can install macOS Sequoia on your Windows PC with the following steps:
- Restart your computer and press the BIOS key to enter BIOS settings.
- Go to the Advanced mode.
- Enable "Virtualization Technology."
- Open Boot settings and disable "Fast Boot."
