I just went to look for that as I'd not heard of it before and was interested. Looks like one has to pay to download it? I cannot find a free link...
I do think I paid $5 to download it, now that you mention it. Sorry I forgot that detail. The only thing about it that cause me any difficulty was that, strangely, there’s no control in the corner of windows to minimize the window. One has to click on the icon in the task bar at the bottom.
But, it is nice and stable, and very Mac-like.
