As of 9-30-2016 we have new compatibility information to share. Now updates are coming for the game, so maybe they finally fixed what ever the issue was and I'll get to play some of my older games I've not touched in the last 6 months. A below represents the corresponding Canon product being compatible with that version of Mac OS X.

However, I just noticed when I launched Steam today, it did an update on the software. As a 20+ years of software developer myself, I find it hard to believe a client app that that allows people to purchase and download games is really that damn hard. Tells me the software developers for this software suck at their job. That was mainly on PC, but I'm running a Mac now and still having the same issues. I figured if I purchased games through Steam maybe it will work better, which a few of the games did, until this occured. I've picked up games that mention Steam on the cover and I didn't even purchase it, because of my experience with this software. I've had games I purchased from the store, that required steam, and even though I have an account, steam will not let me log in with that game. I'm a big gamer, have been most my life and it's sad, because I've never had a good experience with Steam. I'm pretty sure the uninstall will happen, not sure the reinstall will. Open the 'Connect to Server' app from within Finder by pressing Command + K, or by navigating to the Finder menu and selecting Go.
