macOS Catalina (version 10.15) is the sixteenth major releaseofmacOS, Apple's desktop operating system for Macintosh computers. It is the successor to macOS Mojave and was announced at WWDC 2019 on June 3, 2019. Catalina is the first version of macOS to exclusively support 64-bit applications. It will be released as a free update in late September 2019.[2]
The operating system is named after Santa Catalina Island, which is located in southern California.
macOS Catalina will run on these Macintosh computers:[3]
Catalyst is a new platform allowing software to target both macOS and iPadOS. Apple demonstrated several ported apps, including Jira and Twitter (after the latter discontinued its macOS app in February 2018).[4][5]
Mac apps, installer packages, and kernel extensions that are signed with Developer ID must now be notarized by Apple in order to run on macOS Catalina.[6] Devices with an Apple T2 security chip (iMac Pro, 2018 MacBook Pro, Mac Mini, MacBook Air, 2019 Mac Pro) support Activation Lock to prevent use and drive erasure without Apple ID credentials.[3]
The system runs in its own read-only volume, and is separate from all other data on the Mac.[7]
This new feature will allow users to control their devices with voice commands. Even though macOS supported Siri earlier, 'Voice Control' will give control to users on a deeper level. Additionally, on-device machine processing has been used to offer better navigation.[3]
Sidecar is a new feature that allows an iPad that is running iPadOS to be used as a wireless external display. With Apple Pencil, the device can also be used as a graphics tablet for software running on the computer.[5][8] Sidecar is limited to Macs with a sixth-generation Intel processor or newer (iMac Pro, Late 2015 27" iMac, 2016 MacBook Pro, MacBook, 2017 21.5" iMac, 2018 Mac Mini, MacBook Air, 2019 Mac Pro).[9]
The Game Controller framework will add support for several mainstream console game controllers, including PS4 and Xbox One Wireless Controllers, increasing controller support overall on applications developed on the system.[10][11]
In line with iOS, the iTunes software is being split into Music, Podcasts, and TV applications. With its demise, iOS device management has migrated into a native feature in Finder.[12][13] TV on Mac supports Dolby Atmos, Dolby Vision, and HDR10 on MacBooks released in 2018 or later, while 4K HDR playback is supported on Macs released in 2018 or later when connected to a compatible display.[5]
Find My Mac and Find My Friends are merged into a single application, called "Find My".
The Reminders app saw visual and functional overhauls. Attachments can now be added to reminders and Siri can intelligently estimate when to remind the user about a event among other things.[3]
Support for 32-bit applications is dropped. Only 64-bit applications can be run; older 32-bit ones will no longer run.
zsh is the default login shell and interactive shell in macOS Catalina[14], replacing Bash, which was the default shell in macOS Mojave and earlier versions. Bash continues to be available in macOS Catalina, along with other shells such as csh/tcsh and ksh.
Dashboard has been removed in macOS Catalina.[15]
Built-in support for Perl, Python 2.7, and Ruby is deprecated and will not be provided by default in a future release.[16]

Scripting language runtimes such as Python, Ruby, and Perl are included in macOS for compatibility with legacy software. Future versions of macOS won't include scripting language runtimes by default, and might require you to install additional packages.
