Key Features of macOS Catalina 10.15

Full Transition to 64-Bit Applications

One of the most significant changes in macOS Catalina was the complete removal of 32-bit app support. From this version onward, macOS only runs 64-bit applications.

This change improved:

• Performance
• Stability
• Security
• Future compatibility

However, it also meant that many older apps, plugins, and tools stopped working. Creative professionals had to update software such as Adobe apps, audio plugins, and design tools to 64-bit versions.

Sidecar – Use iPad as a Second Display

macOS Catalina introduced Sidecar, allowing users to use an iPad as a secondary display or drawing tablet.

Key benefits:

• Extend or mirror Mac display
• Apple Pencil support for creative work
• Useful for designers and editors

Sidecar improved productivity for users working with graphic design, illustration, and video editing workflows.

iTunes Replaced by Apple Music, TV & Podcasts

Catalina officially removed iTunes and replaced it with three separate apps:

• Apple Music
• Apple TV
• Apple Podcasts

This separation made media management cleaner and more focused, improving performance and usability.

Screen Time for Mac Users

Screen Time, previously available only on iOS, came to macOS with Catalina.

Users can:

• Track app usage
• Set app limits
• Manage parental controls
• Sync Screen Time across Apple devices

This feature helped both individual users and families manage digital habits more effectively.

Enhanced Security & Privacy

macOS Catalina significantly improved system security through:

• Read-only system volume
• Gatekeeper improvements
• App notarization
• Stronger sandboxing

The read-only system volume prevented malware from modifying critical system files, making Catalina more secure than previous macOS versions.
