macOS Catalina, the latest version of the world's most advanced desktop operating system, is now available as a free software update. Apple also says it's made some small usability tweaks to Sidecar, the feature that allows you to use an iPad as a secondary Mac display.
Probably the biggest change in the macOS Catalina 10.15 release is that iTunes is now split into three new apps, Music, Podcasts, and TV.
More iPad apps will be ported to macOS in the coming weeks and months through the Mac Catalyst project. Sidecar can function via a wired or wireless connection; with the former allowing you to charge your iPad while you work.
A new Find My app brings the device-locating functionality to macOS - and even allows for offline tracking of devices. It uses the speech recognition form Siri to allow for control by voice.
Communication Limits for Screen Time, which fall under the same asterisk on that All Features page, also appear to have been delayed until early 2020.
The new Find My app combines Find My iPhone and Find My Friends into a single, easy-to-use app on Mac, iPad and iPhone. There's also a new look for Reminders and a gallery view in the Notes app.

Device and Apple ID management are still available in Catalina, but are done through the Finder app and System Preferences. According to DJ Tech Tools, there is no support or beta that works with Catalina yet, with Pioneer DJ ominously saying: "We will finish our initial research by the end of October 2019 and will post updates on our progress when we know more".
Instead, the Mac joins iPhones in getting separate apps for music, video and other media. Approve with Apple Watch also lets users approve specific security prompts by simply tapping the side button on their Apple Watch. For now, as is usually the best advice, stay away from any major new OS update until you're 100% certain it won't affect your working process.
Reminders has been redesigned with an all-new user interface that makes it easier to create, organize and track reminders.
