Thank you Mald0n, I tried Clover Configurator too. Still no sound. Update: The system boots with no Clover BootArgs at all. I can mount EFI partition OK. For audio: the method I used for 10.13.3, 10.13.4, 10.13.5 does _not_ work with 10.14 (Lilu, AppleALC, HDEF/HDAS, Inject 2, ResetHDA). Graphics show _no_ transparency and are sometimes very slow. However the system appears quite fast and shuts down instantly, good.
