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 Since 2012, the BIOS standard has largely been replaced by UEFI, a newer (and better-looking) interface for managing motherboard settings.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.![Mac Mac](/uploads/1/3/4/8/134826507/456633264.png)
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.![Bios settings for mining rig Bios settings for mining rig](/uploads/1/3/4/8/134826507/101391694.png)
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
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.
Keep in mind that the BIOS on most motherboards do not support using a mouse, so you'll probably have to navigate through the BIOS with the arrow keys on your keyboard. Press 'Enter' to change a selected option in the BIOS. On my Gigabyte motherboard, I have to press F10 to save my changes.
I need to enable something in BIOS, but I do not know how to get to it on the new Mac. I have a quad core iMac with an intel core i5 processor and 8gb of ram. I have the newest Mac Os, Lion, installed as well. Boot OS X, Windows, and Linux on Mac or PC with UEFI or BIOS firmware. Download the latest Clover package from the Getting Started section to begin. From there you need to follow the steps on the installer but use the Customise option to correctly install for your System. Use the settings below, UEFI Motherboard Settings. Install Clover for. Anything you would set in bios, you can write to the non volatile ram from any OS X booted OS and then those variables and settings are applied next boot. There is no bios and no concept of a user navigable hierarchy of settings to adjust before any OS loads to Apple hardware. Most of what you might do “in BIOS” isn't possible.

- 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.
NVRAM (nonvolatile random-access memory) is a small amount of memory that your Mac uses to store certain settings and access them quickly. PRAM (Parameter RAM) stores similar information, and the steps for resetting NVRAM and PRAM are the same.
Settings that can be stored in NVRAM include sound volume, display resolution, startup-disk selection, time zone, and recent kernel panic information. The settings stored in NVRAM depend on your Mac and the devices that you're using with your Mac.
If you experience issues related to these settings or others, resetting NVRAM might help. For example, if your Mac starts up from a disk other than the one selected in Startup Disk preferences, or a question mark icon briefly appears before your Mac starts up, you might need to reset NVRAM.
How to reset NVRAM
Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P, and R. You can release the keys after about 20 seconds, during which your Mac might appear to restart.
- On Mac computers that play a startup sound, you can release the keys after the second startup sound.
- On Mac computers that have the Apple T2 Security Chip, you can release the keys after the Apple logo appears and disappears for the second time.

How To Reset Mac To Factory Settings
- If you're using a desktop Mac instead of a notebook, and settings such as sound volume or time zone are reset every time you shut down and unplug your Mac, you might need to replace the battery inside your Mac. This small battery is on your computer's logic board, and it helps NVRAM retain settings when your Mac is unplugged. You can take your Mac to an Apple service provider to replace the battery.
- If you experience issues with sleep, wake, power, charging your Mac notebook battery, or other power-related symptoms, you might need to reset the SMC (System Management Controller).
