Apple today seeded the tenth beta of macOS 10.15 Catalina to developers, one week after seeding the ninth macOS Catalina beta and over three months after the new Mac operating system update was first unveiled at the Worldwide Developers Conference.

The new macOS Catalina beta can be downloaded using the Software Update mechanism in System Preferences after installing the proper software from the Developer Center.


macOS Catalina eliminates the iTunes app, splitting it into Music, Podcasts, and TV apps. The three new apps offer similar functionality to iTunes, but are split up by feature. iOS device management is still available on the Mac, but it's now done through the Finder rather than iTunes.

With a new Sidecar feature, you can turn your iPad into a second display for your Mac with just the click of a button. The Apple Pencil works with Sidecar, so you can turn your iPad into a drawing tablet in apps like Photoshop and Illustrator.

Your Apple Watch can be used to approve security prompts for passwords and other info in macOS Catalina, and Macs with a T2 chip now support Activation Lock, making them more secure. There's a new Find My that brings the Find My Mac app to the Mac for the first time and even lets you track your devices when they're offline, or, in the case of notebooks, closed.

Screen Time is available on the Mac as well as iOS devices, and Project Catalyst, a new Apple initiative, will let developers easily port their iPad apps over to the Mac to increase the number of Mac apps available.

There's a new Photos interface that surfaces your best photos organized by day, month, or year, there's a new start page in Safari, Mail has new tools for muting email threads and blocking senders, and the Reminders app has been overhauled.

32-bit apps no longer work in macOS Catalina, which is something to be aware of before installing the beta.

My applescript which sets calendar alerts, that worked fine in Mojave, is still failing in this latest beta.

If Catalina goes live without a fix, I guess I'll actually have to debug it :) It's the fact my Feedback says "more than 10" other people have the same issue that gives me hope for a fix.

I have 16 Gigs in my 2012 Mac Mini.😉

Seriously, 8 Gb for macOS, I think Leopard came in at that size, thought macOS was a lot leaner, especially Catalina since it does not support 32 bit Apps, single Arch afaik.
Yes, but then again the sheer volume of features and underlying new code in frameworks dwarfs anything that was Leopard.

Still artwork is not working for movies purchased and ripped. In old iTunes all displayed correctly , on new Catalina B10 still not displayed correctly so not updating main machine. This hasn't been fixed since B1!
