- The layout of the UEFI on Gigabyte motherboards is different from the old BIOS layout, and there are a few new settings that need to be changed to work optimally with Mac OS X. Rather than adding yet another section to our standard OS X installation guides, we've put together a separate guide to cover the UEFI setup process.
- BIOS Updates for Security Vulnerabilities: GRUB Bootloader (Boothole) and RowHammer PC Peripherals / Graphics Card / PC Components / Motherboard CVE-2018-19320, CVE-2018-19321, CVE-2018-19322, CVE-2018-19323, CVE-2019-7630.
- Start by plugging the thumb drive into a USB port. Then to change the BIOS boot sequence: Press the Power button for your computer. During the initial startup screen, press ESC, F1, F2, F8 or F10. (Depending on the company that created your version of BIOS, a menu may appear.) When you choose to enter BIOS Setup, the setup utility page will appear.

First, you need to download the BIOS update file for your specific BIOS version. If you haven't installed Windows on your Hackintosh yet, then you can do this from a separate computer (it needs to be a Windows PC, unfortunately).
If you have a Gigabyte motherboard, simply Google the model name of your motherboard; the official Gigabyte page for your motherboard should be the first result. In the official Gigabyte page, click on the 'Downloads' tab and select 'BIOS' for download type. For example, this is the BIOS download page for my motherboard (a Gigabyte P67A-D3-B3). You'll download a .exe file. Run it; it will prompt your for installation location.

Put the file on a USB drive that has been formatted with the FAT or FAT32 file system. Then plug the drive into the computer whose BIOS you want to update. Boot into the BIOS (you need to press the Delete key at bootup to open the BIOS for Gigabyte motherboards). At the bottom of the BIOS screen, you will see something named along the lines of 'Q-Flash Utility'. This is a tool for updating BIOS software. On Gigabyte motherboards, press F8 to start Q-Flash. Q-Flash should detect the update file on your USB drive. Select that file and press the enter key. After a short update process, your BIOS will be updated.
Once the update process is done, you can reboot and begin your installation of Mac OS X, this time with a supported BIOS version.
If you own an old computer that you want to turn into a Hackintosh, you'll probably have to fiddle with its BIOS, which is basically a traditional-style settings page for your motherboard. Since 2012, the BIOS standard has largely been replaced by UEFI, a newer (and better-looking) interface for managing motherboard settings. However, we believe that enough Hackintoshes these days still use BIOS to warrant a guide for it. Gigabyte motherboards have traditionally been the most widely recommended brand for Hackintoshes, so that's what we'll be covering in this tutorial.
Not sure whether your computer's Gigabyte-brand motherboard uses BIOS or UEFI? Here's a quick guide to differentiating between the two: the interface of BIOS is usually monochrome and entirely text-based. Meanwhile, the interface of UEFI usually has pictures, and allows you to use your mouse pointer. If your Gigabyte motherboard uses UEFI, check out our UEFI settings guide instead.
To enter the BIOS on my own computer's Gigabyte P67A-D3-B3 motherboard, I have to press the delete key when it boots (before the operating system starts). Different manufacturers set different keys for opening the BIOS.
If your Hackintosh already has Mac OS X Snow Leopard, Lion, or Mountain Lion installed, the only thing you'll need to change in the BIOS is the 'Boot Device', so that USB drives have highest priority.
If your Hackintosh doesn't have any version of Mac OS X installed yet, you have to change a few extra BIOS settings. Before starting, reset all of your BIOS settings to their factory defaults. On Gigabyte motherboards, you can reset your BIOS settings to their default by selecting 'Load Optimized Defaults' on the main page of the BIOS. Once your BIOS is running on its defaults, you need to change these three settings:
Boot Device - Change the boot device of your computer so that 'USB-HDD' is first. You need to do this for Unibeast to work. After you finish installing Mac OS X, you should change this setting back to default, so that 'Hard Disk' is the first boot device (this optional, but it will speed up your boot times).
HPET - Change this to 64-bit.
SATA Control Mode (your BIOS might call this a different name) - This will probably already be set to 'SATA', 'IDE', or 'RAID'. Change it to 'AHCI'. Mac OS X only works with AHCI.
