Hey guys. This will help simplify the post install steps when installing Sierra onto an AMD machine. This supports Ryzen, APU, FX and another other AMD CPU that has SSE4.1
Note: The USB drive must be named SierraAMD for the script to work.
Once you've made the USB installer just copy the PostInstall folder to the root of the USB. Once Sierra is installed open up Terminal from the installer and run these commands,
The script will ask for the Volume name you gave the drive when you formatted before installing. Once complete you'll be able to boot into the newly installed Sierra using the boot loader on the USB.
