macOS Catalina or macOS 10.15 is the newest version of the operating system that will run on the Mac from this fall 2019. macOS Catalina’s name was inspired by the Catalina Islands that is off the coast of Southern California.
In macOS Catalina Apple has taken away the iTunes app that’s been a staple to the Mac operating system since 2001. iTunes has been split into three apps: Music, Podcasts, and TV (coming this fall 2019). The new apps are similar in function to iTunes now but are split up by feature. You can still manage your devices in Catalina, but it’s now done through the Finder rather than through an app. Syncing media can be done using the Apple TV, Podcasts, or Music apps.
In the Music app there’s full access to the music library just like in iTunes. Regardless of whether the songs were purchased or ripped from a CD. The iTunes Music Store is included in the Music app, and you can access Apple Music content too.
The Apple TV app is similar to the Apple TV app on the Apple TV and iOS devices, offering up access to TV and movie content for the first time. The new TV app will support 4K HDR content on 2018 and later Macs.
In the new Podcasts app users can access their Podcasts library, which was previously housed in iTunes. There are features for browsing, viewing top charts, and managing your library, plus new editor-curated categories. Podcasts is a simple app but useful for those who listen to a lot of podcasts.
Your 32-bit apps are no longer going to work in macOS Catalina. You’ll get a warning when you install the update. macOS Catalina supports 64-bit apps only, and that means that some of your older apps that haven’t been updated for a while won’t run at all. The Dashboard feature which has long been disabled by default has been officially removed in Catalina.
A new Sidecar feature available in System Preferences lets you turn your ipad into a display for your Mac with just the click of a button. Apple Pencil support works with the ipad with Sidecar, so you can turn your ipad into a drawing tablet in apps like Photoshop. You can extend your display or mirror it so both screens display the same content.
macOS Catalina ramps up the security in macOS, and Gatekeeper. Apple’s security protocol checks all your apps for known security issues. New data protections also require apps to get your permission before accessing your documents.
For those with an Apple Watch set up to unlock the Mac, there’s now an option to approve security prompts by tapping on the side button of the watch. Macs with a T2 chip in them support Activation Lock for the first time, making them useless to thieves much as it does on the iPhone.
A new Find My app is also available in iPadOS and iOS 13 brings the Find My Mac and Find My Friends technology to a Mac app for the first time and it has a feature that lets you track your devices even when they’re offline. This option leverages Bluetooth and the devices of other people who might be around your lost or stolen device, relaying its location securely and anonymously back to you.
Screen Time has expanded to the Mac in macOS Catalina so now you can track your device usage across your all device. Not just iPhone and iPad, for a better picture of how you’re spending your time.
Project Catalyst, known internally at Apple as Project Marzipan, will let developers port their iPad apps over to the Mac with just a few clicks in Xcode and minor tweaks, which will ultimately result in a much greater number of macOS apps available.
There’s a new Photos interface that organizes your pictures by day, month, or year, while also intelligently choosing your best photos so you can relive all of your favourite memories.
In Safari, there’s a new start page that uses Siri Suggestions to display frequently visited sites, bookmarks, iCloud tabs, Reading List selections, and links you’ve been sent in Messages for a more personalized Safari start page.
Mail in macOS Catalina adds new features for blocking emails from specific senders, muting threads, and unsubscribing from commercial email lists. There’s a new Gallery View in notes, along with new view-only collaboration options and folder sharing.
As on iOS, the Reminders app has been overhauled with introducing a new user interface, smart lists, attachment support, and Messages integration to make it easier to create and organize your reminders.
Voice Control lets users who can’t use a Mac in the traditional way operate their machine using solely voice commands through Siri. This feature also works on iOS 13 and iPadOS.
The macOS Catalina beta is limited to developers at the current time, but it will be available to public beta testers starting in July. Apple plans to beta test the update for several months before releasing it to the public this fall 2019.
