Hello! I have the same issue. The Brightness Star App has fixed the brightness issue. It does have a checkbox were you can check for it to start as your system starts. If that dosent work you can always use SystemPreferences>Users&Groups>LogInItems>"+"> then search on the Applications for the Brightness Star Apps. This will enable the ap to start at system Boot. Hope It Helps! -HighSierra Patcher rules!
