ACPI: SSDT-USBX.aml -prebuilt one for this system HW config as per guides

KEXTs: VirtualSMC,RealtekRTL8111,Lilu (whatever-green during install only)

Geekbanch5: Single Core 1302, Multicore 8418, Metal 51454, CL 40414


Known Issues:

Kext for KEXT for Onboard Audio not loaded- as using Platronics headset via USB
Hibernation switched off, - for time being no KEXTs added above minimal ones listed above.

Notes:

After no success with others similar HW based config modifications followed the install guide step by step with clean install,
-had many failed attempts creating USB stick when trying to installing a working boot system to the USB, failing to create USB the would start the boot process to AMD System. Finally all went smooth when using OC 5.7 with Catarina 10.15.4 full install from download list -this one has been released before OC 5.7 release date (can it be that something was not supposed in newer OS releases not available when OC 5,7 was released?-or who knows).
-using Mac Pro.7.1 in plist
-scan policy 0 to be able to see boot drives
-generated UUID via online page— to avoid reuse of existing one.
-Used snapshots function on OC folder in plist editor to match current HW and later on the OC clean menu to insert changes done during install in KEXTs to the config.plist making easy to play with different KEXTs
-used online tool for checking plist consistency and errors
-had to use boot-args v —pikera -keepsyms=1 debug=0x100 to get through the boot and install with whatever-green.
Had to force restart once during install as got grey screen (maybe was not waiting enough)
After install WhateverGreen, had to be removed as it was causing lags/GPU related performance issues .
Post install steps followed to move EFI from USB stick.
System is now stable- no crashes or any other issues while using it (see comment on sleep).
Using for work from home all the day -office apps, videoconferencing , screen sharing connecting to internal and office networks w/o any issues -completely smooth and functional,

Thanks for your sharing. I have a question that did you ever encounter this problem https://forum.amd-osx.com/index.php...als-when-booting-or-waking-up-from-sleep.184/ ?

Not like this. It was rather with having to switch off and on again after not comming back from sleep (no reaction on keyboard or mouse movements). But as I have only basic Kexts-and most likely I would need to add some for proper power management - I was not bothering with this further, just disabled the sleep for time being

Hey there! Can you please post your EFI folder? I have the same setup as you! Thanks in advance

@cp007 did you try a single push to the power button? That sometimes helped me. Otherwise try https://github.com/acidanthera/HibernationFixup/releases with -hbfx-disable-patch-pci in boot args. Also make sure you have hibernatemode set to 0 (pmset -g)

Could you share your EFI folder ?
