I found my flashed 09/10 Mac Pro is restarting whenever I try to render in DaVinci Resolve. Im only attempting to render out 2 min Blackmagic 2k raw clips to prores. Ive tried different output options, tried using gpu option in resolve, reset pram, and tried rendering from and too different hard drives both internal and external, but still the same problem. CPU temps seem to climb pretty quick during render but not enough time to overheat before restart happens (only gets up to about mid 60's celsius and it happens in a matter of seconds).
