New macOS features
macOS Catalina organizes your media from iTunes into three new apps:
Music: Listen to your favorite songs in the new Apple Music app. Your library contains all your music, and For You offers personalized playlists and suggestions. See Music.
TV: Watch movies and TV shows in the Apple TV app. See personalized recommendations in Watch Now, or pick up watching where you left off on another device. See TV.
Podcasts: Browse, subscribe, and listen to podcasts on your Mac. Find your favorite episodes in Listen Now, or discover new ones by searching for host, guest, or topic. See Podcasts.
macOS Catalina also offers many exciting new features, including:
Find My: Locate a lost device, even if it isn’t connected to Wi-Fi. You can also share your location and keep track of those who have shared their location with you. See Find My.
Activation Lock: When Find My Mac is on, you have to enter your Apple ID password to erase and reactivate your Mac. So if your Mac is ever lost or stolen, you can make sure that no one else uses it. See the Apple Support article About Activation Lock on your Mac.
Sidecar: Turn your iPad into a secondary display for your Mac. Spread out your work, draw with Apple Pencil, and more. See Sidecar on your Mac.
Accessibility: Voice Control lets you control your Mac entirely with your voice, thanks to new numbered grids and text editing commands. Know exactly what’s on the screen with improvements to VoiceOver, zoom, and new color filters. See Accessibility.
Apple Account: View everything connected to your Apple ID in one place. Your family can also see shared subscriptions, enabled services, and Ask To Buy settings. See Apple Account on Mac.
Screen Time: Keep track of your activity with detailed reports and custom notifications. You can also control how much time you or your kids spend on apps. See Screen Time on Mac.
Photos: Larger previews and hidden duplicates make your best shots stand out. Choose from curated albums and videos in Memories, then use new editing tools to make them your own. See Photos.
Reminders: Create reminders with times, dates, locations, flags, and attachments. Smart lists automatically sort your upcoming reminders, so you can easily stay organized. See Reminders.
Notes: Gallery view and improved search make finding your notes even easier. You can also rearrange checklists and collaborate in shared folders. See Notes.
Mail: Take control of your inbox. Quickly mute threads, block senders, and unsubscribe from mailing lists. See Mail.
Safari: A redesigned start page lets you pick up where you left off or choose from relevant websites. See Safari.
Security: Your Mac asks for permission before letting an app access your data or capture what’s happening on screen. All new apps are checked for security issues before you run them. Security improvements also make it harder for problems in one area to impact the rest of your Mac.
