macOS Catalina (version 10.15) is the sixteenth major release of macOS, Apple Inc.’s desktop operating system for Macintosh computers. It is the successor to macOS Mojave and was announced at WWDC 2019 on June 3, 2019 and released to the public on October 7, 2019.

Is macOS Catalina still available?

macOS 10.15 Catalina is now available to the public. Do not upgrade to macOS 10.15 Catalina until you have confirmed compatibility with your third-party software and audio/MIDI devices.

Is Catalina better than Mojave?

So who’s the winner? Clearly, macOS Catalina beefs up the functionality and security base on your Mac. But if you can’t put up with the new shape of iTunes and the death of 32-bit apps, you might consider staying with Mojave. Still, we recommend giving Catalina a try.
