You can't upload a file. I believe you can alter what you say you support. So if you had a Mac version uploaded, you could add the flag saying you support it but if the file doesn't exist you are out of luck. Technically you might be able to put the file on another site and include a link to it but that seems a little weaselly. How can we be sure that it is not an updated version? What if someone does the same thing with an updated windows version? I wish I had uploaded a linux version but at this point I suggest waiting it out.

Awesome will wait it out! Thank you so much for answering my question :)
