All three apps have been built from the ground up and offer an experience that's vastly superior to iTunes.
After the update, you will see the Apple TV + service for promotional purposes.
What the new Apple SideCar does is allowing the Mac to run harmoniously alongside the iPad which runs the iPadOS using the latter as the secondary screen.
During installation, you can not use the Mac. Sidecar can function via a wired or wireless connection; with the former allowing you to charge your iPad while you work.
After you upgrade to macOS Catalina, you will retain access to your entire music library as well as your ability to buy new music from the iTunes Store.
Catalina is available now for all Macs from 2012 or newer. The new Podcasts app will provide one with access to over 700K podcasts from different genres. For users with impaired vision, Hover Text displays high-resolution text in a dedicated window when hovering over text and UI elements, and Zoom Display keeps one monitor tightly zoomed in while another at the standard resolution. Some big-name cross-overs you'll be able to download at launch: Twitter, TripIt, Rosetta Stone, Post-It and the game Asphalt 9, among others.
File sharing was initially scheduled to release later this fall following the release of macOS Catalina on Monday.
Did Apple actually nail it the first time around, when iPods and iTunes actually gave digital users complete control over their music collections?
Some other apps have been revamped as well. Happy downloading and do let us know in the comments how the install goes.
With Sidecar, iPad Pro and Apple Pencil owners can draw on their iPads display in apps like Adobe Illustrator and iWork and the content will show up on their Mac.
Photos features a lovely new browsing experience that intelligently showcases the user's best pictures.
Additionally, the Safari browser now boasts an overhauled start page which uses Siri suggestions to recommend frequently-visited sites and bookmarks.
Wondering if you should update today or later?
Notes now has a brand new Gallery View, more powerful search tools and additional collaboration options.
