Hackintosh booting is very slow

I installed Sierra succesfuly, quickly without almost any issue. Using unibeast and multibeast. Resolution, graphics work, (just there is no callibration option which is not important for me right now). The only thing that bother me is that booting is going very slowly. It takes usually one minute. Also another issue which happen randomly is when I restart or turn off the computer from Sierra it doesn't work, it starts to switching off but there is just black screen, computer is running and nothing happen. After 2 minutes I switch off the computer manualy.

Intel Core i7-6700K Intel HD Graphics 530 skylake ASRock Z170 Pro4 - Intel Z170

Thanks in advance for your help
