What kind of issue that you have now?
Have you inject your os-info on your system?
Have you got the CI/QE yet?
You may check if your QE/CI active or not, if you have injected AAPL,os-info correctly.
Check the injection by ioreg -l | grep -e "os-info" and make sure we setup the right one for us.
If you didn't get the os-info injected yet, you may try it by Natit.kext or DSDT injected.
