[HELP] X99 Working, but need some fix

I successfully installed macOS Sierra and everything works fine. But I have some problems that I need some help.

First I have this 2 messages every time I start up the system. https://imgur.com/a/BS7rH

Another problem that I have is when I am exporting vídeo the computer restarts (sometimes). Probably a temperature problem.

My rig: Gigabyte X99 Gaming G1 Wi-Fi i7 5820k MSI GTX 970 16GB RAM DDR4 SSD + HDD Raid0

Thanks.
