I know, I know, enough with these Git clients, use that damn Terminal app! I see your point but for a lot of designers and non-terminal people, having a user-friendly client can be a great way to be introduced to Git. A few weeks ago I was asked to beta test Tower, a soon-to-be released Git client for OS X that is easy to use yet very powerful. The interface is a little more elaborated than other clients like Gity or Gitty, but it that doesn’t seem to affect the ease of use. At the same time, if you like minimal interfaces, you may like Gity’s simplicity better.
On top of the regular Git functions, some of the nice features offered by Tower are a repository manager to keep track of your repos, direct integration with Github, and a stash support.
Tower should be released in November, if you want to read more about it you can visit http://git-tower.com.
