Apple will release macOS 10.15 Catalina today, the latest major update to the company's Mac operating system. Catalina marks the end of iTunes as anchoring on Macs, now the app is broken down into separate apps for Apple Music, Podcasts and Apple TV. Everything iTunes has made should be available in these new, simplified applications. Device and iPhone sync has been moved to Finder.
The new release also introduces iPad application support for macOS due to what Apple calls Project Catalyst, which can launch a wave of software coming from Apple tablets to its desktops and laptops.
Speaking of the iPad, Catalina also includes a new Sidecar feature that allows the iPad to use both secondary displays for your Mac, both wirelessly and when connected. Sidecar supports Apple Pencil, allowing you to run Mac versions of applications such as Photoshop while using the stylus. You can also comment on screenshots or PDFs using a pencil.
Other new additions include the debut of macOS screen time and tougher privacy protection: applications must now request permission to access your desktop, documents, iCloud Drive and external storage. One of my favorite little things in Catalina is activating the lock. Now, any Mac that has a T2 security chip cannot be erased and reactivated without an Apple ID password. Here's hoping to activate activation lock on a Mac is just as much an anti-theft tool as an iPhone.
