Essentially, the new file system should make your macOS life a little easier behind the scenes.
Siri for Mac
After all the little bits and pieces, Apple showed us what we were hoping for - Siri on a Mac. A particularly useful and impressive feature that was demoed live on stage was searching through documents using Siri. The voice assistant will also let you be far more flexible with macOS Sierra - you'll be able to image search online with Siri, and have the ability to drag and drop those images directly into a plethora of apps.
Siri is already on iPhone, iPad and even the Apple TV, so it was only a matter of time before Siri came to Mac too. After all, Microsoft already has Cortana in Windows (and has done since Windows 8.1) and Chrome has Google Now.
