Hello im new to Mac but coming along pretty good, i succesfully installed windows, so thats not a problem, but in the demo video i seen on apple it should that when you restart from windows it will automatically boot OSX on the next boot cycle but mine on restart rebooted back to windows obviously i can hold Option and re-chosse what OS to boot to from the grey screen but is there a way to make one partition the default boot regardless what partion i restart from?
