macOS 12, Monterey on the MSI B365M Mortar

the provided EFI is only a sample for this build, it boots but I highly recommend to build your own EFI so you'll learn about things & how they work, head to the OpenCore Install Guide

notes

• use HfsPlus.efi instead of OpenHfsPlus.efi, found here
• create your own USB map with USBToolBox in Windows
• -v (stands for Verbose) can be removed after installation
• OpenCanopy GUI isn't provided to keep it lightweight, you can download it here
• everything is set as per the Configuration.pdf (0.7.9) by Acidanthera for CFL-based sysstems
• config-iGPU.plist only works with the integrated Intel UHD 630
• make your own SMBus SSDT (SBUS-MCHC) after install
• generate a iMac19,1 SMBIOS using GenSMBIOS
• OpenCore version is 0.7.9
• no Wi-Fi & Bluetooth Kexts included such as OpenIntelWireless
• the provided EFI is able to boot macOS 11 or 12
• the propertry list must be named config.plist
• only use ProperTree to edit plist files, avoid configurators like OCAuxiliary, Clover & OC Configurator
• the SSDT's are prebuilts by Acidanthera, however I recommend to use SSDTTime to generate them or the manual way (as the prebuilts are kinda bloated)
