RIP iTunes: Apple releases MacOS 10.15 Catalina

Apple's latest MacOS version of Catalina is available for download.

Those looking to update to macOS Catalina can check for an update in Settings.

Speaking of games, the update also allows Catalina beta users to play Apple Arcade games for the first time.

The release of macOS Catalina today also sees Apple officially launch Apple Arcade on the Mac. However, machines running High Sierra (10.11), Sierra (10.12) or High Sierra (10.13) must upgrade from the Mac App Store.

Before attempting to install macOS Catalina 10.15, you should first check if your Mac computer is supported.

Among the new features Apple has touted, some of the standouts include Sidecar, which transforms an iPad into an external auxiliary screen (the third-party Duet Display has been doing this for several years); Activation Lock on Macs equipped with the T2 security chip, which lets IT administrators lock up the machine so it's worthless if lost or stolen (and block workers from changing the lock); and a refreshed Safari 13, which features a revamped new tab page.

The Apple TV app brings together different ways to find and watch movies and TV shows into one powerful app, and features Apple TV channels, personalized recommendations and over 100,000 iTunes movies and TV shows to browse, buy or rent. Music, Podcasts, and TV have been split into three desktop apps because the old iTunes app was overburdened and awful to use. Some big-name cross-overs you'll be able to download at launch: Twitter, TripIt, Rosetta Stone, Post-It and the game Asphalt 9, among others. The Find My app now combines Find My iPhone and Find My Friends.

Mail in macOS Catalina adds the ability to block email from a specified sender, mute an overly active thread and unsubscribe from commercial mailing lists.

Reminders has been redesigned with an all-new user interface that makes it easier to create, organize and track reminders.
