If you’re comfortable with these challenges and eager to learn, a Hackintosh can be a rewarding project.
Step 1: Hardware Selection – Choosing the Right Components
The most critical step is choosing hardware that is known to be compatible with macOS. Research is key. Consult Hackintosh communities (such as tonymacx86 and InsanelyMac) to see what components others have successfully used. Pay close attention to the specific models and revisions of each component. A seemingly minor difference in model numbers can make a huge difference in compatibility. Here’s a breakdown of essential components:
* **CPU (Central Processing Unit):** Intel CPUs are generally more compatible with macOS than AMD CPUs. Specifically, Intel’s Core i3, i5, i7, and i9 processors from the Coffee Lake, Comet Lake, Rocket Lake, Alder Lake and Raptor Lake generations are popular choices. Recent AMD CPUs are making headway, but the setup process is significantly more complex.
* **Motherboard:** This is the most critical component for compatibility. Look for motherboards based on Intel chipsets like Z390, Z490, Z590, Z690, Z790 (for Intel CPUs), and X570, B550 (with caution) for AMD. ASUS, Gigabyte, and MSI are popular brands. Check the Hackintosh forums for specific motherboard models that have been proven to work well. Features to look for include good UEFI BIOS support, sufficient USB ports, and adequate expansion slots.
* **GPU (Graphics Processing Unit):** AMD Radeon RX series GPUs (RX 570, RX 580, RX 5600 XT, RX 5700 XT, RX 6600, RX 6700, RX 6800, RX 6900, RX 7900) are generally easier to configure and often offer better performance in macOS than NVIDIA GPUs. NVIDIA compatibility can be more challenging due to driver issues, particularly with newer cards. Older NVIDIA cards like the GTX 970, GTX 980, and GTX 1060 can work but may require specific drivers and configurations. Integrated graphics (Intel UHD Graphics) can also work but may have limited capabilities.
* **RAM (Random Access Memory):** Choose compatible DDR4 or DDR5 RAM based on your motherboard’s specifications. 16GB is recommended as a minimum, with 32GB or more being ideal for demanding tasks. Ensure the RAM speed is supported by both your CPU and motherboard.
* **Storage:** An NVMe SSD (Solid State Drive) is highly recommended for the macOS installation. This will significantly improve boot times and overall system performance. A separate HDD (Hard Disk Drive) can be used for additional storage. Make sure the NVMe SSD is formatted properly (APFS is generally recommended for macOS). Some older SSDs may cause Kernel Panics; research your drive model carefully.
* **Wi-Fi and Bluetooth:** Many motherboards have built-in Wi-Fi and Bluetooth. However, compatibility can be problematic. For the best compatibility, consider using a Fenvi FV-T919 Wi-Fi/Bluetooth card. This card uses a Broadcom chipset that is natively supported by macOS.
* **Power Supply (PSU):** Choose a PSU with sufficient wattage to power all your components. Use a PSU wattage calculator to estimate your power needs. It’s always a good idea to have some headroom.
* **Case:** Select a case that can accommodate all your components and provides adequate cooling.
**Important Considerations for Hardware:**
* **Research, Research, Research:** Before purchasing any hardware, thoroughly research its compatibility with macOS on Hackintosh forums. Look for successful build logs and user experiences.
* **Check OpenCore Guides:** OpenCore is the recommended bootloader for Hackintosh builds. The OpenCore Install Guide (Dortania’s Guide) provides detailed information on compatible hardware and configuration.
* **Read the Fine Print:** Pay attention to specific model numbers and revisions. A seemingly identical component might have different internal hardware that affects compatibility.
* **Plan for Expansion:** Consider future upgrades when choosing your components. Select a motherboard with sufficient expansion slots and a PSU with enough wattage to support future upgrades.
## Step 2: Creating a Bootable macOS Installer
This step involves downloading macOS from Apple and creating a bootable USB drive. You will need access to a working Mac or Hackintosh for this process.
1. **Download macOS:**

* Select your USB drive in the sidebar.
* Click “Erase”.
* Enter a name for the drive (e.g., “Install macOS”).
* Select “macOS Extended (Journaled)” as the format.
* Select “GUID Partition Map” as the scheme.
* Click “Erase”.
* Open Terminal (located in /Applications/Utilities).
* Enter the following command, replacing “Install macOS” with the name of your USB drive and “/Applications/Install macOS [Version Name].app” with the correct path to the macOS installer:
bash
sudo /Applications/Install\ macOS\ [Version Name].app/Contents/Resources/createinstallmedia –volume /Volumes/Install\ macOS –nointeraction
* Enter your administrator password when prompted.
* The process will take some time to complete. Do not interrupt it.
## Step 3: Preparing the OpenCore Bootloader
OpenCore is a modern, open-source bootloader that is widely recommended for Hackintosh builds. It is more flexible and customizable than older bootloaders like Clover.
1. **Download OpenCore:**
* Download the latest release of OpenCore from the Acidanthera GitHub repository:
[https://github.com/acidanthera/OpenCorePkg/releases](https://github.com/acidanthera/OpenCorePkg/releases)
* You will need the “RELEASE” version.
2. **Download Essential Kexts (Kernel Extensions):**
Kexts are essential for macOS to recognize and use your hardware. Download the following kexts:
* **Lilu.kext:** A fundamental kext that enables many other kexts to function.
* **VirtualSMC.kext:** Emulates the System Management Controller (SMC), which is required by macOS.
* **WhateverGreen.kext:** Handles graphics injection and patching.
* **AppleALC.kext:** Enables audio functionality.
* **RealtekRTL8111.kext:** Enables Ethernet functionality for Realtek RTL8111 network cards (if applicable).
* **USBInjectAll.kext:** Helps with USB port configuration. You may need to create a custom USB map later.
* **XHCI-Unsupported.kext:** Provides support for XHCI USB controllers on older chipsets (may not be needed on newer chipsets).
* **NVMeFix.kext:** Fixes compatibility issues with certain NVMe SSDs.
* **SATA-Unsupported.kext:** May be required for certain SATA controllers.
Download these kexts from their respective GitHub repositories (usually under the “Releases” section). Make sure you download the latest versions.
3. **Mount the EFI Partition:**
* Open Terminal.
* Enter the following command to identify the disk identifier of your USB drive:
bash
diskutil list
* Look for your USB drive in the list. The disk identifier will be something like “disk2”.
* Enter the following command, replacing “disk2s1” with the correct disk identifier and partition number for the EFI partition (usually partition 1):
bash
sudo diskutil mount disk2s1
* The EFI partition will now be mounted on your desktop (or in /Volumes).
4. **Create the EFI Folder Structure:**
* In the EFI partition, create the following folder structure:
EFI
└── OC
├── ACPI
├── Drivers
├── Kexts
├── Resources
│ └── Font
├── Tools
└── config.plist
* **ACPI:** Will contain ACPI (Advanced Configuration and Power Interface) files (SSDTs) for patching your system (we’ll get to this later).
* **Drivers:** Will contain UEFI drivers.
* **Kexts:** Will contain the kexts you downloaded in step 2.
* **Resources:** Contains fonts and other resources for the OpenCore boot menu.
* **Tools:** Contains utilities for debugging and troubleshooting.
* **config.plist:** The main OpenCore configuration file.
5. **Copy Files to the EFI Partition:**
* **Drivers:** Copy the following UEFI drivers from the OpenCore package (located in EFI/OC/Drivers) to the EFI/OC/Drivers folder on your USB drive:
* `OpenRuntime.efi`
* `HfsPlus.efi` (required for reading HFS+ volumes)
* **Kexts:** Copy all the kexts you downloaded in step 2 to the EFI/OC/Kexts folder on your USB drive.
* **Resources/Font:** Copy `Font2.eff` from the OpenCore package (located in EFI/OC/Resources/Font) to the EFI/OC/Resources/Font folder on your USB drive. If the “Font” folder doesn’t exist, create it.
* **Tools:** Copy `OpenShell.efi` from the OpenCore package (located in EFI/OC/Tools) to the EFI/OC/Tools folder on your USB drive. This tool is helpful for troubleshooting.
6. **Configure the config.plist:**
This is the most complex part of the process. You will need a plist editor, such as ProperTree, to edit the `config.plist` file.
* **Download ProperTree:** Download ProperTree from its GitHub repository.
[https://github.com/corpnewt/ProperTree](https://github.com/corpnewt/ProperTree)
* **Create a Basic config.plist:** Open ProperTree. Choose `File -> New` to create a new blank `config.plist`. Save it as `config.plist` in the EFI/OC folder of your USB drive.
* **Mount the EFI Partition using ProperTree:** In ProperTree choose `File -> Open …` and navigate to `EFI/OC/config.plist`. This will mount the EFI partition in ProperTree’s left pane.
* **Use the Sample config.plist as a Guide:** The OpenCore package includes sample `config.plist` files in the Docs folder. These files provide a template for configuring your `config.plist`. There are separate sample files for different CPU platforms (e.g., `config.plist` for Coffee Lake, `config_AMD.plist` for AMD). Copy the relevant sample file and rename it `config.plist` and then edit that to include your kexts. Open the sample configuration file in ProperTree and carefully compare it to your blank `config.plist`. You will need to copy and paste sections from the sample file into your `config.plist` and modify them to match your hardware configuration. Pay close attention to the following sections:
* **ACPI:** This section configures ACPI patching. You’ll likely need to add SSDT files (described in the next section) and configure their settings in this section.
* **Booter:** Contains settings related to the boot process.
* **DeviceProperties:** Used to inject device properties, such as framebuffer settings for your GPU. This is where you’ll configure graphics acceleration.
* **Kernel:** The most important section. This section configures kext loading, kernel patches, and other kernel-related settings. You’ll need to add entries for all the kexts you copied to the EFI/OC/Kexts folder. Make sure the kext names match the filenames exactly.
* **Misc:** Contains miscellaneous settings, such as boot menu configuration, security settings, and debugging options.
* **NVRAM:** Configures NVRAM settings, such as boot arguments and display settings.
* **PlatformInfo:** Used to spoof your system’s SMBIOS information (system model, serial number, etc.). This is essential for macOS to recognize your system as a valid Mac. Use the *GenSMBIOS* tool for setting the SMBIOS info. See next section.
* **UEFI:** Contains settings related to UEFI drivers.
* **Important config.plist Settings:**
* **Kernel -> Add:** Add all your kexts here, ensuring they are enabled (`Enabled` is set to `True`) and that the `BundlePath` points to the correct kext file in the EFI/OC/Kexts folder. Kexts should be ordered in the way specified in the relevant OpenCore documentation.
* **Kernel -> Quirks:** These are kernel patches that fix compatibility issues. The required quirks vary depending on your hardware and macOS version. Refer to the OpenCore Install Guide for the recommended quirks for your system.
* **Booter -> Quirks:** These are bootloader patches that fix compatibility issues.
* **Misc -> Security -> SecureBootModel:** Set this to `Default` if you don’t need Secure Boot. If you want to enable Secure Boot, you’ll need to generate your own keys.
* **Misc -> Boot -> PickerAttributes:** This setting controls the appearance of the OpenCore boot menu. Set it to `0` for a basic text-based menu, or `17` for a graphical menu.
* **NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82 -> boot-args:** This is where you specify boot arguments. Common boot arguments include:
* `-v`: Verbose mode (shows boot messages).
* `keepsyms=1`: Keeps symbols loaded for debugging.
* `debug=0x100`: Enables debugging output.
* `alcid=1`: Specifies the audio layout ID (replace `1` with the correct layout ID for your audio codec).
* `agdpmod=pikera`: Required for some AMD GPUs to prevent black screen issues.
* **PlatformInfo -> Generic:** This section contains SMBIOS information. You must generate unique SMBIOS data for your system. Using the same SMBIOS data as someone else can lead to iMessage and iCloud issues. Use GenSMBIOS (see below) to generate this data.
7. **Generate SMBIOS Data with GenSMBIOS:**
SMBIOS data identifies your system to macOS. You need to generate unique SMBIOS data to avoid issues with iMessage, iCloud, and other Apple services.
* **Download GenSMBIOS:** Download GenSMBIOS from its GitHub repository.
[https://github.com/corpnewt/GenSMBIOS](https://github.com/corpnewt/GenSMBIOS)
* **Run GenSMBIOS:**
* Open Terminal.
* Navigate to the GenSMBIOS directory.
* Run the `GenSMBIOS.command` script.
* Select option 1 (“Install/Update MacSerial”).
* Select option 2 (“Generate SMBIOS”).
* Enter the system definition you want to use. Common choices include `iMac19,1`, `iMacPro1,1`, and `Macmini8,1`. Choose a system definition that is similar to your hardware. Check the Dortania guide for recommendations.
* GenSMBIOS will generate SMBIOS data, including Board Serial Number, Serial Number, SmUUID, and SystemProductName.
* **Enter SMBIOS Data in config.plist:**
* Open your `config.plist` in ProperTree.
* Navigate to `PlatformInfo -> Generic`.
* Enter the generated SMBIOS data into the corresponding fields:
* `MLB`: Board Serial Number
* `ROM`: MAC address of your network adapter (without colons).
* `SystemSerialNumber`: Serial Number
* `SystemUUID`: SmUUID
* `SystemProductName`: SystemProductName
## Step 4: ACPI Patching (SSDTs)
ACPI (Advanced Configuration and Power Interface) patching involves using SSDT (Secondary System Description Table) files to modify your system’s ACPI tables. This is often necessary to fix compatibility issues and enable features such as power management, USB port mapping, and battery status.
1. **Identify Required SSDTs:**
The SSDTs you need will depend on your hardware and macOS version. Common SSDTs include:

* **SSDT-PLUG.aml:** Enables CPU power management.
* **SSDT-AWAC.aml:** Fixes the RTC clock.
* **SSDT-USBX.aml:** Defines USB power properties.
* **SSDT-GPI0.aml:** Used for I2C devices.
2. **Download Pre-Built SSDTs (if available):**
Some pre-built SSDTs are available for common hardware configurations. You can find them on Hackintosh forums or in the Dortania OpenCore guide.
3. **Create Custom SSDTs (if necessary):**
If pre-built SSDTs are not available for your hardware, you may need to create your own. This involves using the `iasl` compiler to disassemble your system’s ACPI tables, modifying the tables, and then recompiling them.
4. **Place SSDTs in the ACPI Folder:**
Copy the SSDT files to the EFI/OC/ACPI folder on your USB drive.
5. **Configure SSDTs in config.plist:**
Open your `config.plist` in ProperTree.
* Navigate to `ACPI -> Add`.
* Add entries for each SSDT file you added to the EFI/OC/ACPI folder.
* Ensure that the `Enabled` property is set to `True` and that the `Path` property points to the correct SSDT file.
## Step 5: Installing macOS
Now that you have prepared your USB drive and configured OpenCore, you can install macOS on your target system.
1. **Boot from the USB Drive:**
* Insert the USB drive into your Hackintosh.

5. **Install the Update:**
* Install the macOS update through System Preferences.
6. **Test and Troubleshoot:**
* After the update is complete, thoroughly test your system to ensure that everything is working correctly. If you encounter any issues, consult Hackintosh forums for troubleshooting tips.
## Troubleshooting Common Issues
Building a Hackintosh is not always smooth sailing. Here are some common issues and their solutions:
* **Kernel Panic:** A Kernel Panic is the macOS equivalent of a Blue Screen of Death. It indicates a serious system error. Kernel Panics can be caused by incompatible kexts, incorrect ACPI settings, or hardware issues. To troubleshoot Kernel Panics, boot in verbose mode (`-v` boot argument) to see the error messages. The error messages can provide clues about the cause of the panic. Check your kext versions, ACPI configurations, and hardware compatibility.
* **Boot Loop:** A boot loop occurs when the system restarts repeatedly without booting into macOS. This can be caused by a corrupted EFI folder, incorrect BIOS settings, or incompatible hardware. To troubleshoot boot loops, try booting from a USB drive with a known good EFI folder. If you can boot from the USB drive, copy the EFI folder to your system drive.
* **No Audio:** No audio can be caused by missing or misconfigured audio kexts. Make sure that you have installed AppleALC.kext and that you have specified the correct audio layout ID using the `alcid` boot argument. Check the AppleALC documentation for the correct layout ID for your audio codec.
* **No Wi-Fi:** No Wi-Fi can be caused by missing or misconfigured Wi-Fi kexts. If you are using a Broadcom-based Wi-Fi card, you may need to install additional kexts such as BrcmFirmwareData.kext and BrcmPatchRAM3.kext. Consider using a Fenvi FV-T919 Wi-Fi/Bluetooth card for best compatibility.
* **Graphics Issues:** Graphics issues can range from no graphics acceleration to graphical glitches. Make sure that you have installed WhateverGreen.kext and that you have configured the correct framebuffer settings for your GPU. For AMD GPUs, try adding the `agdpmod=pikera` boot argument.
* **USB Issues:** USB issues can include non-functional USB ports or slow USB speeds. Create a custom USB port map to ensure that all USB ports are functional and that they are configured correctly.
