macOS Catalina is the name of the upcoming operating system that runs Apple’s Macintosh computers. If you use a MacBook, MacBook Pro, Mac Mini, iMac, or Mac Pro, you’ll most likely want to upgrade when it releases this fall. 

Announced at Apple’s World Wide Developers Conference in June of 2019, macOS Catalina promises to have a ton of new features that will make your Mac more productive, easier to use, and probably a bit faster as well. Here’s a quick list of all the big (and some smaller but still important) features the latest macOS update has in store for you.

Music, TV, and Podcasts

It’s the end of an era. iTunes is no longer. macOS Catalina will have three separate apps to do the work of iTunes: Music for your tunes, TV for your shows (as well as movies and premium streaming channels, including Apple TV+) and Podcasts for your favorite digital radio shows. 

Each new Mac app will integrate with the same apps on all your other devices. Listen to a Podcast, watch a movie, or listen to an album on your iPhone, then pick up where you left off on your Mac or iPad.

iPad and Mac Working Together

Apple’s been working on a new system called Project Catalyst that will let developers bring their iPad apps to the Mac with less work than starting from scratch. They’ll run on your Mac just like they do on your iPad, giving you even more screen space and power when running on your Mac. 

In addition, you’ll finally be able to extend (or mirror) your Mac desktop to your iPad natively (without the help of third-party apps) using an app called Sidecar. Feel like turning your iPad into a graphics tablet? Sidecar, as part of Catalina, will let you do just that: draw on your iPad while it mirrors your favorite Mac graphics program using Apple Pencil. You’ll even be able to mark up PDFs using Apple Pencil, your iPad and your Mac, too.

Speaking of integration, your Apple Watch will now be able to authenticate notes, app installations, and passwords from Safari with a quick press of the side button. 

Updates to Mac Apps

Photos on macOS Catalina

Apple’s built-in apps like Photos and Notes will have all-new looks and features, too. Photos will have a newer, more dynamic view that will show off only the best of your images, without duplicates cluttering up the screen (it doesn't delete your duplicates). You’ll be able to browse these favorites by day, month, or year as well as get bigger previews of photos you’ve taken. Apple’s beefed up the AI, as well, which will let the app highlight special events like birthdays, trips, or anniversaries. 

Notes gets a new gallery view and a better search system to find your notes more quickly, as well as shared folders and checklist options. Reminders will be all-new and will include attachments, quick edit buttons, and Siri suggestions from Messages. A new Smart List option will effortlessly organize your Reminders, too, while you’ll also be able to tag people in Reminders for notifications while you chat with them. 

Safari will have an updated start page with favorites and frequently visited sites, and Siri will help bring bookmarks, links, iCloud tabs, and more to the front of your web browser. 

A new Find My app will make sure you can find your Mac, iPhone, iPad or other Apple connected devices from any one of them. Whether you’re on iOS or macOS, you’ll be able to pull up Find My and see where your stuff is. 

Security, Privacy, and Digital Wellbeing

Screen Time on macOS Catalina
Apple Inc. 

Screen Time is coming to the Mac via macOS Catalina, letting you keep an eye on what you or your kids are doing across all the Apple screens you use on a daily basis. You’ll be able to monitor usage, schedule no screen time, and set limits for Mac apps and websites (as well as iOS devices, which already have the feature). You’ll also be able to manage your kids’ communication via Family Sharing. 

macOS Catalina will use newer Macs’ T2 Security Chip to run only trusted software (along with Gatekeeper) and encrypting any data you store. It will also let you authenticate via Touch ID and manage Apple Pay payments securely. Activation Lock will also make sure that you’re the only one who can erase and then reactivate your Mac. The new macOS will also make sure that nothing can accidentally overwrite any system files, keeping all the macOS stuff on its own dedicated system volume, separate from your data. Apps will need to get your explicit permission before accessing any documents (on your Mac, on external drives, or in iCloud) or Desktop files. Any app trying to capture keyboard strokes or images of your screen will similarly need your express permission. 

Accessibility

Apple has always been on the vanguard of native accessibility options, but macOS Catalina takes it to a whole new level. Voice Control will let anyone navigate their Mac using just their voice, along with improved dictation and more robust text editing abilities. It will have more comprehensive commands, too, letting you open and interact with apps via voice. 

Zoom, a super helpful utility for those with visual disabilities, gets even more powerful, too. You can zoom in on one display while leaving the other un-zoomed for the big picture. Hover text will also help you see small fonts with a simple hover of your mouse; great for older eyes as well as visual impairments.

Apple also has a section on their Catalina Preview website showing which Macs will be able to run the latest macOS. According to the chart (above), you'll need an iMac, MacBook, or MacBook Pro from 2012 or later, a Mac Pro from 2013 or later, a MacBook from 2015 on, or an iMac Pro from at least 2017 to run macOS Catalina.

These, of course, are just the big features for Apple’s upcoming OS. As a modern operating system, there are literally thousands of systems and features that come into play. If you’re looking to get all of the large and small details of Apple’s latest macOS Catalina, the company has a web page just for that.
