Skype for Mac was updated to version 7.13 to support the most recent release of OS X, El Capitan, and add a couple of useful new features.
The Skype app for Mac now supports Mac OS X 10.11 El Capitan and the OS’s new Split View mode. Similar to Snap View on Windows, Split View allows users to more easily multitask and split their screen between more than one window. Skype for Mac also received some new features that make it easier to find friends to chat with. The Mac client now comes with the ability to easily add contacts from your Mac or other address books, as well as the ability to verify your mobile number so people can more easily find your Skype profile.
There was also some bug fixing that took care of an issue which was causing Skype to crash on quit. There is also one known issue with this build that when switching to a conversation with a large group there can be a noticeable drop in performance. The Skype team assures that they are working on resolving this known issue and hope to release a fix soon.
If you are running Mac OS X 10.9 or above you can download Skype for Mac 7.13. And the Skype team is also asking for your feedback so they can continue to improve the Skype experience. Feedback can be shared within the app itself by going to Help and selecting Provide Skype Feedback.
