Hackintosh Four Letter Words - 15 important acronyms that you'll need to know

Learning these terms is your first step to getting a fully working hackintosh build. Take your time and study and memorize these so the meaning is second nature. Then you'll be able to communicate with and understand those that are trying to help you have a successful first experience with hackintoshing.

In grade school, you learned the letters of the Alphabet first. Then you combined those together to create words. After that you put those words together into sentences and then paragraphs. In the language of computers and technology it works differently. Long and complex terms often get shortened into abbreviations or acronyms. A universal serial bus port gets renamed as a USB port, a solid state drive is called an SSD.

Each of the four letters represents a word in it’s own right. An acronym is an abbreviation formed from the initial letters of other words and pronounced as a word. Read up on the meaning and learn more background info on these acronyms in the tonymacx86 glossary. There are many informative internet sites dedicated to defining and explaining these too. Use Google search. I've listed only the most important ones for hackintosh owners. There are many more to learn.


ACPI - Advanced Configuration and Power Interface

AHCI - Advanced Host Controller Interface

APFS - Apple File System

BIOS - Basic Input/Output System

CMOS - Complimentary Metal Oxide Semiconductor (related coin battery)

DSDT - Differentiated System Description Table

EHCI - Enhanced Host Controller Interface - controller for USB 2.0

GUID - Globally Unique Identifier (related to GPT or "GUID Partition Table")

Kext - Kernel Extension

NVMe - Non Volatile Memory express SSD - (solid state drive with an M.2 connector)

PCIe - Peripheral Connect Interface express - (see the video below)

SATA - Serial ATA (Advanced Technology Attachment)

SSDT - Secondary System Description Table

UEFI - Unified Extensible Firmware Interface (Macs use EFI)

xHCI - Extensible Host Controller Interface - controller for USB 3.0

There are also some important three letter acronyms...
  • ESP - EFI System Partition - (first small 200MB partition on your boot drive)
  • GPT - GUID Partition Table - (the partition scheme used when formatting your drive)
  • HFS Plus - Hierarchical File System - A file system developed by Apple. Replaced by APFS.
  • MAS - Mac App Store
  • MLB - Main Logic Board
  • SIP - System Integrity Protection
  • SMC - System Management Controller (a physical "chip" on Mac motherboards)
  • SSD - Solid State Drive
Finally, I'll add two of my own four letter acronyms...
  • FSMC - Fake SMC (System Management Controller) - a kext that emulates the SMC chip in real Macs
  • VSMC - Virtual SMC - The successor to Fake SMC. A new kext that is still in active development.
Sometimes you'll also hear people shorten the word Motherboard to MOBO or Mobo. It's one and the same thing.

It's a good idea to copy and paste these acronyms into a text document that you'll save on your desktop for easy reference. May you experience great success and fully enjoy your new Hackintosh computer !
