Q: What is a Hackintosh?

A non-Apple computer configured to run macOS using compatible PC hardware combined with a custom bootloader and configuration files to emulate a real Mac environment.

Q: Is building a Hackintosh legal?

Installing macOS on non-Apple hardware violates Apple’s End User License Agreement (EULA). It is generally not illegal for personal experimentation but not permitted for commercial use.

Q: What hardware is best for a Hackintosh?

The best hardware closely matches real Apple systems, with Intel CPUs (6th Gen to Core Ultra), AMD Radeon GPUs, compatible chipsets, and Intel-based Wi-Fi cards offering higher success rates.

Q: Can I build a Hackintosh with an AMD CPU?

Yes, macOS can run on AMD Ryzen CPUs using kernel patches, but Intel CPUs provide better native compatibility.

Q: What is OpenCore?

OpenCore is a modern Hackintosh bootloader that provides near-native macOS behavior and is the recommended bootloader for new installations.

Q: Is Clover still supported?

Yes, Clover is still supported but less recommended compared to OpenCore for modern systems.

Q: Which macOS versions support Hackintosh?

Hackintosh systems support macOS versions from Leopard up to recent releases, depending on hardware compatibility.

Q: Do NVIDIA graphics cards work on Hackintosh?

Only older NVIDIA GPUs work on older macOS versions; modern NVIDIA GPUs are incompatible with current macOS releases due to lack of driver support.

Q: What is an EFI folder?

The EFI folder contains the bootloader, drivers, kexts, and configuration files required to boot macOS on a Hackintosh.

Q: What are kexts?

Kexts (kernel extensions) are drivers that enable hardware functionality such as audio, Ethernet, USB, and graphics.

The I/O Registry is a dynamic database that describes a collection of “live” objects (nubs or drivers) and tracks the provider-client relationships between them. When hardware is added or removed from the system, the Registry is immediately updated to reflect the new configuration of devices. A dynamic part of the I/O Kit, the Registry is not stored on disk or archived between boots. Instead, it is built at each system boot and resides in memory.

The I/O Registry is made accessible from user space by APIs in the I/O Kit framework. These APIs include powerful search mechanisms that allow you to search the Registry for an object with particular characteristics. You can also view the current state of the Registry on your computer using applications provided with the developer version of OS X.

This chapter describes the I/O Registry architecture and the planes the Registry uses to represent relationships between objects. It also provides an overview of device matching and introduces applications that allow you to browse the Registry.

The I/O Registry Explorer

The developer version of OS X provides an application called the I/O Registry Explorer that you can use to examine the configuration of devices on your computer. I/O Registry Explorer provides a graphical representation of the I/O Registry tree.
