Software providers for OS X respond in kind. Apple moves much faster than Microsoft in terms of deprecating their software and APIs. Sure it works, but you can't complain when you can't interact with the rest of society who isn't as unwilling to move forward as you seem to be. Consumers like you are technological isolationists. You have a working setup, and you're unwilling to change to a modern OS or hardware configuration because you are unable to adapt to new workflows. The only acceptable outcome I see is being able to decline updating Steam and maintaining access via an older, 10.6 supported client Please provide additional details - about how this will work.

I most certainly do have a problem if this termination of support will mean I can no longer access my library with no technical reasons for this. I have no problem with Steam as a platform, phoning home for authentication etc., for the price of convenience. Upgrading my OS is not an option leave that out of the discussion. To be clear, I have a number of applications which did not make the Carbon/Cocoa transition and will not function on 10.7+.

My workflow requires non-broken Spaces, and I standardized my OS version upon purchase so mission-critical software continues to run. To all those about to say 'it's free, just update' - not an option. Yes, this laptop is still running 10.6.8. My only use of Steam on this hardware is to play these games with my fiancee while I'm on the road. Despite being 5 years old, it still plays Source games perfectly well with settings low (e.g., Portal 2), as well as other titles such as Risk of Rain and Crypt of the Necrodancer. The laptop I'm typing this on is a late-2010 Macbook Air. To Valve: I expect to maintain the ability to access the library of games I've paid for, and which currently work perfectly well, on this hardware and OS. After updating Steam today, there is a pop-up saying that 10.6 support will terminate in November 2015.
