macOS Catalina Overview
Released as OS version 10.15, macOS Catalina marked a monumental shift in Apple's desktop operating system ecosystem by officially deprecating 32-bit application support in favor of pure 64-bit architecture. This critical architectural evolution delivered enhanced security, superior RAM utilization, and buttery-smooth multitasking performance.
According to documentation on Wikipedia on macOS Catalina, Catalina introduced revolutionary additions like Sidecar (turning your iPad into a secondary display), the division of iTunes into dedicated standalone media apps (Music, Podcasts, and Apple TV), and robust Gatekeeper app verification protocols to keep malicious software at bay.
