Deleting support for 32-bit apps
 Apple has been warning for years that 32-bit app support will be removed, and this will happen when macOS Catalina is available. Most apps should now be updated, but if you have an older Mac app that says "[App] is not optimized for your Mac and needs updating" when you start it, this app will not work at all in Catalina.
If an app you need occasionally displays this message at startup, do not upgrade to Catalina until there is a newer version of this app or you can find a replacement.

Music, Television and Podcasts Receive Separate Apps
Mac users have been asked to separate iTunes for years, and in macOS Catalina, this is finally becoming reality. There are three new apps for media: music, television and podcasts. In the Music app, you can stream Apple Music, manage your library, and buy songs from the iTunes Store.
The TV app is the new home of all videos. Find all the TVs and movies you've bought on iTunes, as well as the iTunes Store, where you can download even more. Here you can also stream content from Apple's new TV + subscription service when this fall finally launches.
The podcasts app is not groundbreaking, but it's nice to finally be able to manage subscriptions, download episodes, and discover new shows outside of iTunes. All three apps use a very similar interface. And they're noticeably slimmer and more responsive than their previous iTunes implementations.
If you miss iTunes, do not worry – on Windows, the classic iTunes app will continue to work.
Use your iPad as the second display.  An iPad used as a second display with the Sidecar app in macOS Catalina on a MacBook Pro.

The new Sidecar feature lets you turn your iPad into a second display, and works with any iPad that supports Apple Pencil, although Apple does not As far as we've heard, Sidecar should work on Macs released in 2016 or later.
You can already do this if you have a third-party app like Duet Display however, it is now available in macOS and iPadOS.  To enable Sidecar after upgrading your iPad to iPadOS 13 and your Mac to macOS Catalina, go to System Preferences> Sidecar and select your device from the drop-down menu out You can also enable a sidebar to access keyboard shortcuts and a touch bar at the bottom of the screen, just like a MacBook Pro.
Use your Apple Pencil under macOS.
When you connect your iPad to your Mac with Sidecar, you can take full advantage of the benefits of using Apple Pencil on the touch screen. You can draw in apps like Illustrator, fix photos in Affinity Photo, or use the preview to mark PDFs or sign your name.
However, note the fine print on the Apple website that some apps require updates to work with Sidecar this way.
Running iPad apps on your Mac
Retaining the iPad theme, macOS Catalina also makes it easy for iOS developers to port iPad apps to their desktops. Apple calls this catalyst, and in the next few months, more and more apps will come to the Mac, as the developers familiarize themselves with the porting process.
Catalyst is the official name for Project Marzipan, first introduced at Apple's Worldwide Developers 2018 Conference (WWDC). When Apple released macOS Mojave, it included a handful of apps based on this technology, including news and voice notes. Catalyst puts it in the hands of third-party developers.

Apple used the racing game Asphalt 9 to demonstrate the function when they announced Catalina. The presentation pointed out that the mobile-friendly game uses an even more powerful desktop machine for higher resolutions and more impressive visual effects.
However, not only games are ported. Apple also highlighted iOS apps such as Twitter TripIt and Morpholio. Expect more apps to appear on the Mac as developers who previously targeted iOS find it easier than ever to make Mac versions.

- Photos: A new look that is equivalent to iOS 13 appears. It's easier to check your library Browse by day, month or year. And now it's easier to identify "moments" like traveling abroad and celebrating.
- Memories: This app was created from scratch and reflects iOS 13. You can now add attachments, mark people, and browse reminders through smart lists of terms such as Today and Marked.
- Notes: A new gallery view makes it easier to search content, and the search is more powerful. You can now share entire folders with notes and collaborate with others in iCloud. In addition, there are bulleted lists and simple drag-and-drop options.
- Safari: The browser received the usual annual updates to improve rendering performance and web standards. There's also a new home page with Siri suggestions for contextual links to bookmarks, iCloud tabs, and links from reading lists and messages.
- QuickTime Player: A brand new picture-in-picture mode is just one of the upgrades for this app. In addition, there is now a movie inspector window where you can find more technical information about the current file. You can also create a movie from a sequentially numbered folder of H.264, HEVC, or ProRes images.
