New features in latest macOS Catalina

Apple announced the latest version of macOS at WWDC on 3 June 2019. Following in Apple’s recent custom of naming macOS versions after places in California, it’s called macOS Catalina after Santa Catalina island which lies off the coast of  Los Angeles. Here’s everything you need to know about macOS Catalina.

What is macOS Catalina?

It’s the next version of the Mac operating system and was announced at Apple’s Worldwide Developers’ Conference on 3 June 2019. It has several new features but is probably most notable for killing off iTunes and replacing it with three new apps: Music, Podcasts, and Apple TV.

When will macOS Catalina be released?

Apple didn’t give a macOS Catalina release date when it previewed it. However, in recent years the final version of Mojave, High Sierra, and Sierra were all released towards the end of September, a couple of weeks after Apple’s special event to launch new iPhones.

Developers have been able to download and install the beta version since the week of WWDC and Apple said it will release a public beta in July.

How to upgrade to Catalina the right way

If you’re excited about macOS Catalina and plan to download and install the public beta as soon as it’s available, there are a few things you should do to prepare

  • Backup your Mac. Use Time Machine or another backup tool to make a complete backup of your Mac right before you upgrade. Better still, make a bootable clone, so that if the worst happens, you can boot straight back into your old set up.
  • Clear out the clutter

      Most of us don’t do a clean install when we upgrade, we just install the new OS over the old one. That’s fine, but make sure you clear out junk files and other clutter first. Installing a new OS on a cluttered Mac is like spending time decorating a house with shaky foundations. My favorite way to clear out the clutter, and the easiest method I’ve found, is to use CleanMyMac X. It has lots of different tools to get rid of unnecessary clutter. But the easiest way to use it is to click Smart Scan.

      1. Download and install CleanMyMac X
      2. Launch it from your Applications folder
      3. Choose Smart Scan and press Scan

      You may be surprised to find you can reclaim tens of gigabytes of space before you upgrade to Catalina because CleanMyMac X deletes years’ worth of system junk.

      What are the new features in macOS Catalina?

      1. No more iTunes!

          That’s right, Apple has finally killed off iTunes. After joking that Apple was going to add lots of new features like a calendar and reminders to iTunes, Apple’s vice president of software engineering Craig Federighi announced that iTunes was no more. It will be replaced in Catalina by three separate apps: Apple Podcasts, Apple TV, and Music. The contents of your existing iTunes Library will be split across those three apps and synced via iCloud. Apple says Podcasts, TV, and Music are “designed from the ground up to be the best way to enjoy entertainment on your Mac.” The Apple TV app will support Apple’s forthcoming Apple TV+ streaming subscription service and will allow you to “handoff” to any screen connected to an Apple device.

           2. iPad apps on Mac

          Apple announced that new technology would make it easier for developers to port iPad apps to the Mac. It said that several apps were already lined up, including Asphalt 9: Legends, DC Universe, Jira, TripIt, and Fender Play.

           3. Sidecar

          MacOS Catalina allows you to use an iPad as a second screen for your Mac, in a feature Apple calls Sidecar. You can either extend your desktop onto the iPad screen or have the iPad mirror your Mac’s display. Sidecar also allows you to use your iPad and Apple Pencil like a graphic tablet for drawing or painting, or for marking up PDFs in Preview.

           4. Voice Control

          MacOS Catalina will allow you to navigate your Mac using just your voice. It also brings better dictation, and the ability  to zoom in on one screen while keeping your main screen at 100%. You’ll be able to launch and interact with apps, using numbered labels next to clickable items or by superimposing to click, select, and drag using your voice. Catalina will also let you hover over text to see a window with large text, to make it easier to read.

           5. Improved built-in apps

          Reminders has been completely re-designed in Catalina, and creates smart lists of reminders to make them easier to find. You can also add attachments to reminders, create new ones from the toolbar and let Siri suggest new reminders from Messages.

          Safari gets an updated start page and Siri suggestions, while Notes gets a new gallery view, better search, and shared folders.

          The Photos app in Catalina improves the way it displays your photos, highlighting the best shots and relegating duplicates and not-so-great photos.

          The new Mail app has a new classic layout, as well as the ability to block senders and mute threads. And the Unsubscribe link now appears above the email header.

          6. Find My

          The new Find My app in Catalina replaces Find My Mac, Find My iPhone, and Find My Friends, and puts them all in one place. It can now find your Mac even if it’s offline and sleeping, by sending Bluetooth signals that can be detected by nearby Apple devices and relayed to iCloud.

           7. Privacy and Security

          Privacy has been one of Apple’s key themes in recent years and it has been beefed up in the new macOS. Apps will now have to ask your permission before they can access files in your Desktop or Documents folders, as well as iCloud Drive and external volumes. And whenever any app tries to access keystrokes or take a photo or video of your screen, macOS will let you know.

          In terms of security, Catalina adds Activation Lock, meaning only you can erase and reactivate your Mac, just like an iPhone or iPad. And if you have an Apple Watch, you’ll be able to use it to authenticate unlocking locked notes, approve app installations, and view passwords in Safari preferences.

           8. Screen Time

          Another theme of Apple’s recent releases has been helping users reduce the amount of time they spend in front of a screen.

          And this now includes your Mac’s screen. Screen Time for the Mac. Screen Time allows you to set limits for apps and websites across all your devices, schedule downtime, and monitor usage. You can combine apps and websites into groups, like entertainment or gaming and set limits for those. Family sharing allows you to set limits for other family members, like children, and you can then set communication limits to control who they communicate with during the day and during downtime.

          • There are two new additions to Apple’s Home app and HomeKit developer kit. The first allows you to store recordings made by a HomeKit-enabled camera when activity is detected in iCloud and then view them in the Home app, share them, or save them to your Photos Library. The other addition is that you can now play songs, playlists, and radio stations from Apple Music through HomePod or Airplay 2 speakers using scenes and automation in the Home app and with other HomeKit accessories.
          • iCloud Drive

            iCloud Drive is improving with every version of macOS. In Catalina it gains the ability to share folders with a private link, just like Dropbox and Google Drive. Apple has also improved the integration of macOS with third-party cloud storage services.

            9. Restore from snapshot

            In Catalina, if you update macOS and then discover an app you need to use is not compatible with the update, you can roll back to the previous version using a snapshot stored in the Recovery partition just before the update.

            10. QuickTime Player

            Apple’s video player gets support for picture-in-picture, timecode support, the ability to create movies from folders of images, and an improved movie inspector.

            There are lots of smaller new features too, like new relationship labels in Contacts, Cantonese keyboard predictions, and new Japanese predictions, and there’s a new Indian English Siri voice.

            Will my Mac be able to run Catalina?

            If you have a MacBook Air, MacBook Pro, Mac mini, or iMac made in 2012 or later, yes it will. Likewise, if you have an iMac Pro, made in 2017 and later, it will run Catalina. For heavyweight Mac Pros, the list of supported models starts from 2013. If your Mac is older than that, it’s not supported for Catalina.


            MacOS Catalina promises to be a fantastic upgrade to macOS. It brings performance improvements and lots of new features, and strengthens the link between Mac and iOS. It’s important that you upgrade the right way though and backup your Mac first. You should also use CleanMyMac X to clear out clutter before upgrading.

            That way you won’t carry junk files to the new OS and you’ll have more room for the upgrade.
