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.

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.

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.

Start browsing.

An updated start page helps you easily and quickly access your favorites and frequently visited sites. And Siri suggestions surface bookmarks, iCloud Tabs, and links from your reading list, as well as those you receive in Messages.

Screen Time.
Now on Mac.

macOS Catalina brings all your favorite Screen Time features to Mac, giving you greater insight into how you’re spending your time. Monitor usage, schedule downtime, and set limits for both apps and websites across all your devices. And with Family Sharing, you can set app and communication limits for your kids to help them focus on the right things.

Communication Limits

Communication Limits let you choose who your children can communicate with throughout the day and during downtime, so you can make sure they’re always reachable.

Combined Limits

With Combined Limits, you can combine individual apps and websites, and even whole categories, into a single, easy-to-manage limit. Set a limit for a group of apps and websites, like gaming or your favorite streaming apps.

One More Minute

Need an extra minute to wrap up what you’re doing? You’ll get a notification when you’ve reached your time limit, so you can quickly wrap up a conversation, save a file, or close a game session before your time runs out.

Increased security.
Greater privacy.

With macOS Catalina, there are enhanced security features to better protect macOS against tampering, help ensure that the apps you use are safe, and give you greater control over access to your data. And it’s even easier to find your Mac if it’s lost or stolen.

More secure hardware.

The Apple T2 Security Chip keeps your Mac secure by ensuring that you’re running trusted software and automatically encrypting your stored data. It also provides secure authentication for Touch ID. And now macOS Catalina features Activation Lock, so only you can erase and reactivate your Mac.

Safer-running software.

macOS Catalina runs in its own read-only volume, so it’s separate from all other data on your Mac, and nothing can accidentally overwrite your system files. And Gatekeeper ensures that new apps you install have been checked for known security issues before you run them, so you’re always using good software.

Data protections.

Apps must now get your permission before directly accessing files in your Documents and Desktop folders, iCloud Drive, and external volumes, so you’re always in control of your data. And you’ll be prompted before any app can capture keyboard activity or a photo or video of your screen.

The new Find My app combines Find My iPhone and Find My Friends into a single, easy-to-use app on Mac, iPad, and iPhone. Find My can help you locate a missing Mac — even if it’s offline and sleeping — by sending out Bluetooth signals that can be detected by Apple devices in use nearby. They can then relay the detected location of your Mac to iCloud so you can locate it in the Find My app.

It’s all anonymous and encrypted end-to-end so no one, including Apple, knows the identity of any reporting device. And because the reporting happens silently using tiny bits of data that piggyback on existing network traffic, there’s no need to worry about your battery life, your data usage, or your privacy.

Powerful features to empower everyone.

macOS Catalina includes new features to help everyone get the most out of Mac. Tools for users with low vision allow you to zoom in on a paragraph of text or the entire screen.

Zoom Display

If you have two screens, you can keep one screen zoomed in close while the other remains at a standard resolution. It’s great for everyday work and giving a presentation.

Hover Text

Hover Text makes it easier to view text on your Mac display. Just hover over any text with your cursor and press Command. You’ll get a dedicated window with large, high-resolution text. You can even choose the fonts and colors.

macOS Catalina

The power of Mac.
Taken further.

Featuring all-new, dedicated apps for music, TV, and podcasts. Smart new features in the apps you use every day. And Sidecar, which lets you use iPad as a second Mac display.
