How about leaving beautiful images stored in Google Photos as a screen saver (screensaver) on your Mac? Now you can, and in an "official" way.
Google yesterday launched the Featured Photos Screensaver for Mac, which uses featured public images selected on the service as decoration of your computer screen.
They are fantastic landscapes and places photographed by Google Photos users worldwide. You, if you want, can make your catches available to those who may appear there too. What's more, it has support for multiple monitors, showing different photos on each one.
Featured Photos Screensaver requires OS X Mavericks 10.9 or higher. It is also available in Android version (which originally appeared as a Google Pixel exclusive feature) and, if you own a Chromecast, you certainly knew it before.
