  • No more iTunes ̵
    1; Apple removed iTunes in macOS Catalina and split it into three new apps: Music, TV, and Podcasts. These three apps offer all the features previously available on iTunes, so you can continue to access your music library, access the TV shows and movies you've purchased, and listen to your favorite podcasts. You can also shop in the iTunes Store.
  • Finder Sync – Because there is no iTunes app, you can not manage your connected devices with iTunes. Instead, you plug in an iPhone or iPad On your Mac, you can see it on the left side of the Finder window, where you can access the same controls you had in iTunes on a Mac with an Apple Watch, but in MacOS Catalina, the Apple Watch also be used to authenticate passwords or approve app installs when you double-tap the page key. This is especially useful on Macs without Touch ID. To access the settings, open System Preferences and select the Security & Privacy section.
  • Sidecar – Sidecar is a new feature in macOS Catalina that lets you use your iPad as a secondary display. The easiest way to enable Sidecar is to click on the AirPlay icon on the Mac. If you have a Sidecar-compatible iPad, it will appear in the list of available devices. Sidecar is limited to newer Macs and works on the iPad only with iPads that support Apple Pencil. For more information, see our Sidecar Manual.
  • iPad Apps for Mac – In macOS Catalina, Apple has introduced new "Catalyst" developer tools that make it easier for developers to port their iPad apps to Mac. This means that you can expect some of your favorite iOS apps available on the Mac. Catalyst apps are still being introduced, but some high profile options like GoodNotes 5, Carrot Weather, HabitMinder and more are already available.
  • Find My – There's a new Find My app on the Mac that lets friends and devices be found for the first time. Find My combines Find My Mac and Find My Friends and offers everything you need from a single source. With Find My Even, you can find your Mac when it's closed and without a Wi-Fi connection by using a Bluetooth connection to other nearby iPhones and Apple devices. With the new features of Find My you can find a lost or stolen device better.
  • No more 32-bit apps – macOS Catalina does not support 32-bit apps. Therefore, some older apps may not work anymore. This mostly only applies to apps that have not been updated for a long time, but it's still something that can surprise users. For more information, see our 32-bit Mac app manual.

Many of the apps on the Mac have been redesigned with new features. For example, reminders have a completely new look and a more user-friendly interface, while photos have a new view that organizes everything by day, month, or year. With Notes, you can share folders for the first time, and in Safari, there is the option Picture by Picture.
