Known Issues

Conexant CX20632 requires VoodooHDA.kext which is incompatible with HDMI Audio. If you wish to use HDMI Audio output replace VoodooHDA.kext with AppleALC.kext and inject audio channel 11.
Skylake Sleep issue cause reboot on wake. Disable sleep in Engergy Settings.

Installation

Important Note :

This guide isn’t a Vanilla install guide since I couldn’t get the BCM94352Z to work with kexts installed on the EFI partition For a Vanilla install, simply skip the Wireless LAN part and use a Wifi-Bluetooth USB Key instead

BIOS Settings

Disable Fast Boot
Enable USB boot
UEFI Boot order, make sure your USB device is first to boot
Secure Boot : Legacy Support Enable and Secure Boot Disable
Disable : Virtualization Technology for Directed I/O (VTd)
Enable : M.2 SSD (if you use a NVMe SSD)
Uncheck M.2 WLAN/BT (if you don’t have a compatible M.2 Combo Card)
Disable Wake on lan
Set Video Memory to 64 MB

Installation USB Key

Create an USB Key with Mojave manually or using a software like Diskmaker

Installation of Clover on the installation disk

I used Clover V2.4 Release 4798

Customize installation

NOTE : These are the settings are for motherboards doesn’t support UEFI.

Uncheck Clover for UEFI booting only
Uncheck Install Clover in the ESP
Boot Sectors :
- Check Install boot0af in MBR
Clover for BIOS (legacy) booting
- Clover EFI 64-bits SATA
Uncheck Bios Drivers, 64 bits
Uncheck FileVault 2 Bios Drivers, 64 bit
UEFI Drivers check :

Download Clover Configurator and copy it on the installation key.

Boot on USB and install Mojave. I chose to format the disk in APFS.

During the installation the system will reboot a couple of times. When the system reboot on the clover screen make sure you Inject Intel GFX and set Input FakeID : 0x19120000.

If you don’t want to enter these settings on clover boot screen you can edit the config.plist from your installation key and set them.

Post Installation

Add Clover on Boot disk

Copy Clover Configurator and use it to mount the EFI Partition of your system.

You can mount manually your EFI Partition. On a terminal window Identify the EFI partition on your disk with the command

diskutil list Create a mount point
mkdir /Volumes/efi Mount partition
sudo mount -t msdos /dev/disk0s1 /Volumes/efi

Add kexts and ssdt patches

Copy the EFI folder on your Installation key on the EFI of your Add the following kext in /EFI/kexts/Other

Lilu.kext (https://github.com/acidanthera/Lilu)
VoodooHDA.kext (https://sourceforge.net/projects/voodoohda/)
