After months of beta testing, Apple has rolled out macOS 10.15 Catalina to public users. You can download and install macOS Catalina if you have a compatible Mac. The macOS Catalina brings tons of new features such as the Apple Arcade, Screen Time, Voice Control, Sidecar, and Find My app. It has also replaced iTunes with three independent apps – Apple Music, Apple Podcasts, and Apple TV.

Step 4: Download macOS Catalina through the Mac App Store or System Preferences.

Note: Your Mac might request additional resources. Here's how to create macOS Catalina 10.15 bootable USB flash drive installer for a clean install on your Mac.
