Since the iPhone 6s and 6s Plus respectively were introduced, a good handful of new features have also been introduced along with them, including the possibility of taking "Live Photos". This function means that when we take a shot with our iPhone, the software captures the seconds before the photo in both video and audio, so that when viewing it and thanks to 3D Touch, we can see it in motion, thus providing more life to photos.
In the current stable version of OS X, these photos improved only can be viewed through the Photos application, which greatly limits the ability to share them thanks to iCloud. Nevertheless on OS X 10.11.4 beta version launched a couple of days ago, we can see how Live Photos can now be shared in all its splendor, that is, preserving this motion feature, through the Messages application on Mac.
To specify a little more, before when we attached a photo to Messages that had been taken with the iPhone and the Live Photos function activated, it would only send the still image losing both sound and movement prior to the photo. With this latest beta version of El Capitan, however, now Live Photos can be sent from the Photos application on Mac when it is synced with the latest iPhones, or viewed on our Mac when sent from iPhone.
As in iOS, Live Photos are distinguished by a special icon that identifies them in the upper left corner, and now when we open them in the form of a preview with Quick Look, a button is added so that when we press it we can see it in motion these Live Photos. However unfortunately if we drag and drop the photo to the desktop, automatically turns it into a still image.
If you are interested in trying the latest beta of OS X, you just have to sign up in the public beta testing program that Apple makes available to users or if you are a registered developer, you can find it in the Mac Dev Center or in the updates tab of the App Store.
