Kexts-and-plist

i5-8500 + B360 + ~~GTX 1060 6GB~~ RX580

Components used for this build:

macOS updated to 10.14.5
updated efi drivers and kexts to the latest
SMBIOS changed from iMac18,3 to iMac19,1 for better power management (PM), idle frequency increased to 1.3GHz from 0.8GHz (see below)
added CPUFriend.kext and CPUFriendDataProvider to decrease the idle frequency back to 0.8GHz, by changing the four values in the frequency vector of iMac19,1 (Mac-AA95B1DDAB278B95.plist) from 0D to 08. Credit goes to TheRacerMaster and acidanthera/CPUFriend

iMac18,3 iMac19,1 iMac19,1 w/ CPUFriend
'AAPL,ig-platform-id' changed from '0300923E' to '0300983E'. Either '0300913E' or '0300923E' will break the CPU PM - idle frequency will never get down to lower than 2GHz. Don't know why. '0300913E' is automatically assigned by macOS/WhateverGreen (but it breaks CPU PM) if no properties was assigned by the plist.
changing SMBIOS and adding CPUFriend has negligible effects on performance

updated efi drivers and kexts to the latest
removed '/Graphics/Inject Intel' and '/Graphics/ig-platform-if'
updated '/Devices/Properties/PciRoot(0x0)/Pci(0x2,0x0)' and 'AAPL,ig-platform-id', 'framebuffer-patch-enable' and 'framebuffer-stolenmem' (see vanilla guide), otherwise Mojave (10.14.2) would boot into a prohibit sign, -v shows 'unable to allocate runtime area'

updated efi drivers to the latest
set SIP to disabled (CsrActiveConfig '0x67'), otherwise macOS 10.14.2 would boot into a prohibit sign, possibly due to not being able to load unsigned kexts (see wiki)

Jumped ship from nVidia to AMD. The plist can stay the same if you're just lazy or if it doesn't give you any issue. The only thing need to change when switching from nVidia to AMD is to tick off 'System Parameters/NvidiaWeb', but in my case it boots up without any issue with this option ticked, even with the web driver installed.
macOS updated to Mojave
'config.plist/Graphics/ig-platform-id' changed to '0x3E920003' (connectless UHD630) to get native support from Mojave
remove igpu plist, currently not yet succeed to get iGPU works on Mojave. Use ig-platform-id '3E9B0007' can boot into Mojave but into black screens on either DVI or HDMI. This can possibly relate to framebuffer but I haven't managed to solve it. If you know how to do this, please share it with me. Cheers.

Rename config_iGPU.plist to config.plist if you're using iGPU (for example the dGPU is in an RMA...)
kexts and drivers were updated to latest
The repo should be Majove ready, currently awaiting for nVidia's driver to test
A custom USB SSDT was created in /ACPI/patched. It disables all unused USB ports on the mobo, plus the USB 3.0 capability of one of the front panel USB 3.0 ports. If you're not using the exact mobo, or you wish to use the port number patch instead, please don't include the 'ACPI' folder in your EFI, and enable the port limit patch, '10.13.6+ by PMHeart', in 'KernelAndKextPatches' in the plist.

Or, my x230 repo has detailed steps on how to construct the whole thing - just need to be aware that the kexts and the plist are different. https://github.com/littlegtplr/Hackintosh-X230-macOS
