I recently got myself a Macbook Pro and promptly installed Steam on it (mainly, so that I could play the Binding of Isaac).
While I have quite a few games that are compatible with OS X in my Steam library, the majority are not, and still they are pointlessly displayed when I view my library from my Mac.
Is there any way for me to only see the Mac-friendly games I have in my library? I have quite a few, and doing this manually would be quite tedious, not to mention I would then have to rely on my memory to remember which games are actually available for my Mac.
When looking at your library, select Mac Games from the drop down next to the search function.
