macOS Catalina, the latest version of the world’s most advanced desktop operating system, is now available as a free software update. With macOS Catalina, users are able to enjoy Apple Arcade, a groundbreaking new game subscription service featuring new, exclusive games from some of the world’s most creative developers. Adding to great entertainment on the Mac, Catalina also features all-new Mac versions of Apple Music, Apple Podcasts and Apple TV apps. A new feature called Sidecar extends Mac desktops with iPad as a second display, or tablet input device using Apple Pencil with Mac apps. Voice Control, a transformative accessibility feature, allows Mac to be controlled entirely by voice. With Mac Catalyst, a new technology in Catalina that makes it easy for third-party developers to bring iPad apps to Mac, users will begin to see their favorite iPad apps in Mac versions, including Twitter, TripIt, Post-It, GoodNotes and Jira, with more to come. And for the first time, Screen Time comes to Mac, giving users insight into how they spend time in apps and on websites, and the ability to decide how to spend their time.

Also available with macOS Catalina is Mac Catalyst, a new technology that lets app developers easily build Mac versions of their shipping iPad apps. The iPad ecosystem comprises over a million iPad apps, and now users will see more of their favorite titles come to Mac than ever before, including apps like Twitter, GoodNotes, TripIt from SAP, Post-it, Morpholio Board, Rosetta Stone, Jira, Proloquo2Go and others. These titles and more will be available, starting as early as today, on the Mac App Store for users to download and enjoy, and other exciting Mac Catalyst-developed apps will be released in the weeks ahead.

Security improvements in Catalina better protect macOS from tampering, help ensure apps are safe, and give users greater control over access to their data. macOS Catalina now runs on a dedicated, read-only system volume, which means it is completely separate from all other data, and nothing can accidentally overwrite critical operating system files. Gatekeeper, Apple’s technology to ensure only trusted software runs on a Mac, now checks all apps for known security issues, while new data protections require all apps to get permission before accessing user documents. Every Mac with the Apple-designed T2 Security Chip now supports Activation Lock, just like on iPhone or iPad, so if a Mac is ever misplaced or stolen, only the owner can erase and reactivate it. Approve with Apple Watch also lets users approve specific security prompts by simply tapping the side button on their Apple Watch.
