As always, this update will be available as a free download in the Mac App Store.
This version completely rethinks the way you interact with media. Instead of using iTunes for everything, there are a handful of new apps specifically designed for each task — Music, Podcasts and TV.
Mac users will also notice a huge update to Photos. It borrows many of the new features that you can see in iOS 13, such as the ability to view photos by days, months or years with a curated selection of shots. The company tries to identify the best photos using artificial intelligence.
If you’ve been using Duet Display or Luna Display, macOS Catalina lets you use your iPad as a second Mac display. It’s as easy as opening the AirPlay menu and selecting your iPad to extend your desktop. The feature is called Sidecar.
Apple is also adding new accessibility features. For instance, you can open apps, click on dropdown menus and navigate apps much more easily with your voice.
More interestingly, this new version of macOS opens up the ability to port iPad apps to the desktop using Project Catalyst. Some developers already said that they plan on taking advantage of that feature, such as Twitter, Gameloft and Atlassian.
