Skype is launching Skype for Mac 5.4 Beta. The launch introduces the same Facebook integration found in Skype 5.5 for Windows. We are excited to finally deliver Facebook integration to our Mac users.
 
You’ll now be able to IM and connect with your Facebook friends without leaving Skype. You’ll also be able to read and update your News Feed, as well as comment and “Like” your Facebook friends’ posts — all within Skype for Mac. To connect to Facebook, simply sign into Skype, click on the Connect to Facebook tab and enter your Facebook sign in details.
