macOS 10.15 Catalina is an operating system that was designed and developed by Apple in 2019 alongside Apple’s personal computers. The system has been released on October 7, 2019, and was available for Free from Mac App Store, or was preinstalled on currently sold computers. This software gets the last update (10.15.7) on September 24, 2020, and later has been replaced by a newer version of macOS 11 Big Sur.
macOS 10.15 Catalina is the first version of macOS to support only 64-bit apps and the first to include Activation Lock. The operating system is named after Santa Catalina Island, which is located off the coast of southern California.
iTunes has been replaced by separate Books, Music, Podcasts, and TV apps, in line with iOS. iOS device management is now conducted via Finder.
Catalyst is a new software development tool that allows developers to write apps that can run on both macOS and iPadOS. macOS Catalina runs on all standard configuration Macs that support macOS Mojave. 2010–2012 Mac Pros, which could run Mojave only with a GPU upgrade, are no longer supported.
Today macOS 10.15 Catalina is 4 years old!
