Can I filter games by platform ?

I just discovered SG+ as I was looking for a way to filter games by platform (aka I only want to see mac games) but it doesn't seem to have this feature.

Is there a script somewhere that would allow me to filter games for mac ?

At the moment I have to click on a GA, click on the steam price so I can see in the steam sotre if the game is running on mac, I searched the forum for scripts or ideas but came up empty ended.

Thank you for your help.
