The new macOS Catalina beta can be downloaded using the System Update software update mechanism. As with all new betas, macOS Catalina should not be installed on a primary machine because it is premature release software and has errors.
macOS Catalina eliminates the iTunes app and divides it into music, podcast and TV apps. The Apple Music and Apple Podcasts apps are available now, while the Apple TV app is coming later this year.
The three new apps offer similar functionality to iTunes, but are broken down by feature. IOS device management is still available on Mac, but is now done through the Finder instead of iTunes.
With a new Sidecar feature, you can turn your iPad into a different screen for your Mac with just a click of a button. Apple Pencil works with Sidecar so you can make your iPad a character tablet in apps like Photoshop and Illustrator.
Your Apple Watch can be used to authenticate security references for passwords and other information in macOS Catalina and Macs with a T2 chip now support activation lock, making them more secure. There's a new Find My that brings the Find My Mac app to the Mac for the first time, and even lets you track your devices when disconnected, or, in the case of laptops, shut down .
Screen time is available on both Mac and iOS devices, and Project Catalyst, a new Apple initiative, allows developers to easily port their iPad apps to Mac to increase the number of Mac apps available.
There's a new image interface that surfaces your best photos organized by day, month or year, there's a new Safari home page, Mail has new tools to mute email threads and block senders, and the Reminders app is overhauled . 32-bit apps no longer work in macOS Catalina which is something you need to be aware of before installing beta.
