Different colors on export

I never dealt with this problem when I was using PC. Now that I upgraded my working machine to Mac, it always export different color (Undersaturated, a tad brighter on the light and shadows, etc) I tried different fixes on the web, but still no luck. Not sure if its a bug issue, but whenever I exported on a windows PC before, the colors stays the same. 

Its giving me another tedious work to compare and adjust basically doing trial and error on the colors. EVERYTIME.
