macOS Catalina (version 10.15) is the sixteenth and current major release of macOS, 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 and released to the public on October 7, 2019. Catalina is the first version of macOS to support only 64-bit applications and the first to include Activation Lock.[3][4]

The operating system is named after Santa Catalina Island, which is located off the coast of southern California.

## System requirements

macOS Catalina runs on all standard configuration Macs that support Mojave. 2010–2012 Mac Pros, which could run Mojave only with a GPU upgrade, are no longer supported.[4] Catalina requires 4 GB of memory, an increase over the 2 GB required by Lion through Mojave.[5][6]

* iMac: Late 2012 or newer
* iMac Pro
* Mac Pro: Late 2013 or newer
* Mac Mini: Late 2012 or newer
* MacBook: Early 2015 or newer
* MacBook Air: Mid 2012 or newer
* MacBook Pro: Mid 2012 or newer, Retina display not needed

## Changes

### System

#### Catalyst

Catalyst is a new software-development tool that allows developers to write apps that can run on both macOS and iPadOS. Apple demonstrated several ported apps, including Jira and Twitter (after the latter discontinued its macOS app in February 2018).[7][8]

#### Gatekeeper

Mac apps, installer packages, and kernel extensions that are signed with a Developer ID must be notarized by Apple to run on macOS Catalina.[9]

#### Activation Lock

Activation Lock helps prevent the unauthorized use and drive erasure of devices with an Apple T2 security chip (iMac Pro, 2018 MacBook Pro, Mac Mini, MacBook Air, 2019 Mac Pro).[4][10]

#### Dedicated system volume

The system runs on its own read-only volume, separate from all other data on the Mac.[4]

#### Voice control

Users can speak more commands to their devices than Siri allows. On-device machine processing is used to offer better navigation.[4]

#### Sidecar

Sidecar allows a Mac to use an iPad (running iPadOS) as a wireless external display. With Apple Pencil, the device can also be used as a graphics tablet for software running on the computer.[8][11] Sidecar requires a Mac with Intel Skylake CPUs and newer (such as the fourth-generation MacBook Pro), and an iPad that supports Apple Pencil.[12][13]

#### Support for wireless game controllers

The Game Controller framework adds support for two major console game controllers: the Dualshock 4 of the PlayStation 4 and the Xbox One controller.[14][15][16][17]

### Applications

#### iTunes

iTunes is replaced by separate Music, Podcasts, and TV apps, in line with iOS. iOS device management is now conducted via Finder.[18][19] The TV app 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.[8]

#### Find My

Find My Mac and Find My Friends are merged into an application called Find My.

#### Reminders

Among other visual and functional overhauls, attachments can be added to reminders and Siri can intelligently estimate when to remind the user about an event.[4]

#### Removed or changed components

macOS Catalina exclusively supports 64-bit applications. 32-bit applications no longer run (including all software that utilizes the Carbon API as well as QuickTime 7 applications, image, audio and video codecs). Apple has also removed all 32-bit-only apps from the Mac App Store.[20]

zsh is the default login shell and interactive shell in macOS Catalina,[21] replacing Bash, the default shell since Mac OS X Panther in 2003.[22] 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.[23]

The ability to add Backgrounds in Photo Booth was removed in macOS Catalina.

Built-in support for Perl, Python 2.7 and Ruby are included in macOS for compatibility with legacy software. Future versions of macOS won't include scripting language runtimes by default, and might require users to install additional packages.[24]
