Adobe is releasing upgraded Adobe CC apps to members on June 17th 2013, and they are recommending that Mac subscribers be running Mac OS X 10.7 or later before updating. Although some of the new Adobe CC apps will work with OS X 10.6, many have known problems including Photoshop CC.

Side note: When Adobe releases upgrades for CC apps, members are not required to install them, and can continue to use their existing versions of Adobe CC apps for as long as their membership is active.
