The developers of MacFreelance don't have the game listed on their website which could also mean that the product is not discontinued from development.
The only place I've found it was on a third party website, but even so, no download was available.
Because of that, it's impossible to say if it works on OSX Sierra or not. If you have the setup package and Sierra OSX, then simply try to install it.
The software is not available for purchasing. I've followed all the available links and although they lead to the official website, a 404 page is displayed instead which could mean one thing: the software was discontinued. Afterwards, I visit the official website with hope to find it, but if you check the All Products page, you will see that MacFreelance is nowhere to be found.
