This fixes my shutdown/restart problems :)

My MOBO ASUS ROG-STRIX-X470-F-GAMING + Ryzen 7.

Only problem was the SMBIOS, I found that iMac14,4 works with Displayport. iMac14,4+ only showed up on my HDMI connected monitor.

MAKE SURE THAT YOU HAVE A WORKING CLOVER ON YOUR USB DRIVE (usb installer you used to install macOS) AS THIS TUTORIAL CAN FAIL. BOOTING WITH THE CLOVER ON THE USB WILL MAKE THE USB PORTS WORK AGAIN (GenericUSBXHCI.kext is in /EFI/CLOVER/Kexts/**).

Automated version (thanks XLNC)
Spoiler:
1. Open the Terminal app.

2. Run the command :
Code: Select all
curl -s -o ~/Desktop/ryzenusbfix.sh https://raw.githubusercontent.com/XLNCs/ryzenusbfix/master/ryzenusbfix.sh && chmod +x ~/Desktop/ryzenusbfix.sh && ~/Desktop/ryzenusbfix.sh

3. Let the script do its magic.

4. Reboot and enjoy

NOTE : If you don't have a functional USB port to operate your MacOS (not keyboard or mouse working), use your bootable AMDHS_installer or HighSierraAMD USB to boot to your installed macOS drive. That will allow you to use your USB ports temporarily . Then you can run ryzenusbfix to fix your USB ports and boot without the USB installer.

Hi!
I do this method but now I can't boot, and the USB give me a error too in the file boot.efi... How can the USB stop working?
I have this from the first time I installed High Sierra on Ryzen and haven't any problem...

Any easy way to fix the USB and Boot to fix the problems?
