Enjoy your favorite iPad apps now on your Mac. Extend your workspace and expand your creativity with iPad and Apple Pencil. And discover smart new features in the apps you use every day. Now you can take everything you do above and beyond.

What's the difference between the macOS combo and the regular update?

The macOS regular update only includes the files needed to update from the immediate previous version, for example from 10.5.2 to 10.5.3. The combo update includes all the files necessary to update from the last major version. You would want to download the combo update if you're going from 10.5.0 to 10.5.3.

The supplemental update focuses on security issues only.

Music, TV, and podcasts take center stage.

iTunes forever changed the way people experienced music, movies, TV shows, and podcasts. It all changes again with three all-new, dedicated apps --- Apple Music, Apple TV, and Apple Podcasts --- each designed from the ground up to be the best way to enjoy entertainment on your Mac. And rest assured; everything you had in your iTunes library is still accessible in each app. iCloud seamlessly syncs everything across your devices --- or you can back up, restore, and sync by connecting the device directly to your Mac.

Presenting Apple Music on Mac.

The new Apple Music app is the ultimate music streaming experience on Mac.1 Explore a library of 50 million songs, discover new artists and tracks, find the perfect playlist, download and listen offline, or enjoy all the music you've collected over the years. And find it all in your music library on all your devices.

Apple TV. Premiering on Mac.

The Apple TV app for Mac is the new home for all your favorite movies, shows, premium channels, and --- coming soon --- Apple TV+. Watch everything directly in the app or enjoy it offline, and discover the best of what's on in the Watch Now tab. You can even pick up where you left off on any screen, across all your devices. And for the first time, 4K2 and Dolby Atmos3-supported movies are available on Mac.

Listen up. Podcasts on Mac.

More than 700,000 of the best entertainment, comedy, news, and sports shows are now available on your Mac with Apple Podcasts. Search for podcasts by title, topic, guest, host, content, and more. Subscribe and be notified as soon as new episodes become available. And in the Listen Now tab, you can easily pick up where you left off across all your devices.

The apps you love. Right on your Mac.

Experience your favorite iPad apps now on your Mac. With Mac Catalyst, developers can easily create Mac apps from the iPad apps you already know and love. They run natively alongside your existing Mac apps so you can drag and drop content between them. They take full advantage of the larger screen and powerful architecture of your Mac. And because they are built from their iOS versions, they provide a seamless experience across your devices. Enjoy a broad range of Mac apps --- from travel, entertainment, and gaming to banking, education, and project management.

The Twitter for Mac app takes full advantage of the native Mac features like multiple windows, drag and drop, keyboard shortcuts, and more. See more of what's happening on a larger screen and easily work alongside your other Mac apps.

The apps you use every day, made extraordinary.

With macOS Catalina, the apps you love are now more beautiful and intelligent than ever. So your everyday tasks are easier than ever.

Photos. Focus on your best shots.

Photos has a new immersive, dynamic look that showcases your photos and memories. See only the best shots in your library, without the duplicates and clutter. Browse your favorite photos by days, months, and years and get larger previews of all your photos. And Photos is even smarter, so it can highlight important moments like birthdays, anniversaries, and trips.

Notes. Easier to find. And easier to share.

A new gallery view and more powerful search help you find your notes quicker than ever. Shared folders let you collaborate on entire folders of notes with another person or a group. And new checklist options let you move completed items to the bottom, quickly reorder items using drag and drop, and more.

Organization. Reorganized.

The Reminders app has been completely rebuilt, with an all-new design and new ways to easily create, organize, and keep track of reminders. Add attachments to reminders, create or change reminders with the quick edit buttons, and let Siri suggest new ones found in Messages. Smart lists automatically organize and display your upcoming reminders. And if you tag someone in a reminder, you'll be notified the next time you're chatting in Messages.
