This is my OpenCore setup for Ryzen 5 2600, ASRock B450 Pro4 with onboard LAN & audio. It runs Mac OS 11.1 Big Sur and is based on OpenCore 0.6.4.

Replace config.plist with config_release.plist if you want to hide debugging info.

• CPU: AMD Ryzen 5 2600
• Mainboard: ASRock B450 Pro4
• Audio: Realtek ALC892 (also a Creative Soundblaster Z, but see Troubleshooting for info on that)
• Storage: Samsung SSD EVO 840 (SATA) & Samsung SSD 970 EVO Plus (NVMe)
• GPU: AMD RX 580

Everything except:

• Power management
• Sound card: SoundBlaster Z (see Troubleshooting)
• Booting Windows from inside OpenCore (BSOD on startup)

• Drivers/Tools/Resources/Bootstrap: As explained in the Getting Started guide. Nothing special here.
• ACPI:
  • SSDT-EC.aml: Has to be generated on your machine using SSDTTime. You will hang at [BSSTART] without it
  • SSDT-USBX.aml: I think I used a prebuilt here, although I'm not sure, probably from the official prebuilts mentioned in the Getting Started guide
  • SSDT-XHC.aml: I have no idea where I got this from, sorry. It's definitely not from ryzen-catalina or ryzenmacpro. You might not need this, but I guess you most likely run into USB 3 issues without it.
• Kexts:
  • AMD-USB-Map.kext: My system hung at "IOUSBHostInterface deferred" or smth like that without it (potentially related to SSDT-XHC.aml). Sorry, I don't know where I got this from, I think some dude from Reddit posted it and it worked. Maybe there's an "official" build of this, but I won't touch this unless something breaks.
  • AppleALC.kext: I use alcid=2 and it seems to work fine (see Troubleshooting for more info on audio)
  • AppleMCEReporterDisabler.kext: Not sure if this is absolutely necessary, but it didn't do any harm
  • Lilu.kext: Required.
  • NVMeFix.kext: Haven't checked if it's absolutely necessary, but my NVME SSD works out of the box (check if you have the latest firmware!)
  • RealtekRTL8111: For onboard LAN with Realtek Gigabit LAN
  • VirtualSMC: Required.
  • WhateverGreen: Required.
• config.plist:
  • I set language code to de:3 (German) because MacOS kept resetting itself to an ANSI keyboard (had en_US:0 there first)
  • I disabled a few debugging flags to speedup boot

• This is the debug branch with debugging enabled by default, using debug versions of OpenCore as well as all the kexts
• If that doesn't spit out useful info, switch to the debug branch to get the debug binaries as well

• I used OpenCore release to speed up booting (kexts are still debug), so if you run into issues, switch to OpenCore debug first
• System hangs at [BSSTART] (or smth like that): Properly generated EC.aml was missing
• System hangs at "IOUSBHostInterface" (or smth like that): AMD-USB-Map.kext and possibly SSDT-XHC.aml was missing
• Disconnect other sound cards (I almost went crazy until I found this): acidanthera/bugtracker#1000
• How to get 5.1 audio working:
  • Create new device in Audio-Midi-Setup.app that connects the 3 lines into a single device
• Mac OS keeps opening the DVD drive on boot. Unplug the DVD drive. Seriously this drove me nuts.
