TweetDeck 3 with refreshed UI now available for Mac

Following an update to the Windows, Chrome, and web apps, the new TweetDeck is now available for Mac. The update has the slightly changed layout found in the recently-refreshed apps, which has a redesigned navigation bar pinned to the left. Other additions include a new translation feature, and the option to add a “Followers” column that shows you the bios of everyone that follows you. It’s available as a free download from the Mac App Store.
