Is there a differences is the speed at which the cycles are performed on a mac vs. windows. I have been using the steam sync across both platforms and have yet to notice any issues, but I was playing around with other peoples solutions from spacechem.net and they aren't working for me on my mac. One of the solutions mentioned that the cycle output was different on a mac, but I cannot find any documentation or corroborating evidence of such.
Mainly I have noticed that some of the solutions for the fewest symbols/cycles just don't even work on my mac. I rarely get a chance to use windows so I am not able to directly test this.
