Compatibility Support Module (CSM) is a component of UEFI firmware, which provides compatibility with the old BIOS by simulating the BIOS environment, thus allowing the use of the old operating system and some optional Roms that do not support UEFI. Clover and OC boot support UEFI boot. Disabling CSM makes it easy for BIOS to find the boot loader.

Second, disable safe startup.

Secure boot prevents unsigned boot loaders from starting from any internal disk or USB drive. Clover or OC boot does not support secure startup. Secure boot must be disabled in the BIOS to start Black Apple.

To disable secure startup, simply "clear secure startup key" or delete PK key.

Third, set the operating system type to other operating systems.

When starting from a third-party operating system that does not support secure startup of Microsoft signature, please set "Operating System Type" to "Other Operating Systems" for optimized functions.

Fourth, set Sata as AHCI.

Advanced Host Controller Interface (AHCI) mode allows you to use advanced features on SATA drives, such as hot plug and native command queuing (NCQ). AHCI also allows the hard disk to run at a higher speed than the traditional IDE mode.

Verb (short for verb) disables CFG locking.

CFG locking prevents macOS from writing to a specific area in the BIOS. MacOS does this because of power management and other reasons. If it is inaccessible, it will not start.

Intransitive verbs disable Intel virtualization technology /VT-X

Multiple Intel CPUs adopt Intel virtualization technology. This technology, formerly known as Vanderpool, enables the CPU to work as if it had multiple independent computers, so that multiple operating systems can run on the same computer at the same time.

Intel Virtualization Technology (VT), also known as the VT-x extension, allows direct access to the CPU under the virtual machine, thus improving the performance of virtualization software such as VMWare/Parallel Desktop.

But for many users of #Hackintosh, VT-X will not cause any problems, but if you are a novice, you can try to install and configure Hackintosh to disable Intel virtualization technology and install it. If necessary, you can enable virtualization technology after installation.

Seven, disable ventricular tachycardia.

VT-d, especially IOMMU specification. Extensions allow you to access the physical hardware under the virtual machine (for example, a system running Linux can run Windows on the virtual machine. If there is no VT-d, the graphics card will simulate and the game speed will be slow. The graphics card can enter the straight-through mode, which can be accessed as real hardware under Windows (nvidia driver can be installed), and the performance of the graphics card is similar to running native Windows real-time preview. But for many black Apple users, VT-D will not cause any problems, but if you are a novice, you can try to install and configure Hackintosh to disable VT-D and then install it. After installation, you can enable VT-D as needed.

Eight, enable XHCI exchange

Nine, disable the old USB support

X. Disable the USB keyboard and mouse simulator.

The above settings are only valid for motherboards with UEFI BIOS. If you are using an old motherboard, please refer to the following settings:

Load the optimized default value, that is, reset the BIOS to the factory settings.

Turn on UEFI boot mode support in BIOS and turn off CSM (ignore part of BIOS).

In the BIOS? HPET？ Set to? Open or enable

Setting HPET mode must be 64-bit.

Set SATA? For AHCI

Change the execution disable bit to enable (also called XD function)

Set the maximum CPUID value limit to disabled.

Has the BIOS EHCI switch been set to? come into use

Set traditional USB support to enabled.
