Key Features of macOS Catalina
64‑bit Only Architecture
macOS Catalina only supports 64‑bit applications.
This improves security, performance, and long‑term compatibility, but older 32‑bit apps will no longer run after upgrading.
Before updating, it is important to check whether your critical software is available in 64‑bit versions.
Dedicated Music, TV and Podcasts Apps
Catalina replaces the old iTunes app with three dedicated media apps: Music, TV and Podcasts.
This separation makes it easier to manage audio, video and podcast content, with a cleaner and more focused interface for each media type.
Sidecar: Use an iPad as a Second Display
The Sidecar feature allows a compatible iPad to be used as a second display for your Mac.
This is ideal for creatives and multitaskers, giving more screen space for drawing, editing and working with multiple windows at the same time.
Enhanced Security and Privacy
Catalina introduces stronger security protections.
The system volume is read‑only, helping to protect core system files from accidental changes and malware.
Gatekeeper and app verification are stricter, and privacy permissions are clearer, giving you more control over how apps access your data.
Screen Time on Mac
Screen Time is now available on macOS.
It lets you track app usage, set limits and monitor productivity across your devices.
Tools like Downtime and App Limits help you stay focused and reduce distractions.
Improved Device Management in Finder
Many device management features that used to live in iTunes are now integrated into Finder.
It is easier to back up, restore and transfer files for iPhone and iPad using a familiar interface.
This change is convenient for users who rely on wired backups and local management.
