I'm planning to get all three S&M seasons during the Meet The Players sale, either on Steam (if Telltale bring the deal to it! :D) or on Telltale (if they don't). However, I noticed the second season only has PC system requirements and no Apple icon, suggesting it may be PC-only. But, the second season is available for Mac on Steam.
Does the second season on Telltale's website include the Mac OS X version? I'm planning to get a Mac soon, so having the Mac version as well would be great.
