Emanouel Posted October 12, 2017 Author Share Posted October 12, 2017 No idea then. Are you sure the config changes are applied? I mean, the generated config file is in correct place in boot partition. Also make sure the serials are unique (use "generate new" button).  apparently, a lot of high sierra users are having the same issue, so I'll just wait until someone figure out the problem and share the way to fix, I'm fine now with everything working but that Thanks a lot for help !
