Apple this morning introduced the newest version of macOS, the operating system that runs on the Mac. macOS Catalina is now available in a beta capacity for registered developers who are able to download it for testing purposes.

The new macOS Catalina beta can be downloaded from the Apple Developer Center, and once installed, subsequent betas will be available through the Software Update mechanism in System Preferences.


As with all new betas, you're not going to want to install macOS Catalina on a primary machine as it is early release software and could have major bugs.

Apple delved into cross-platform apps in macOS Catalina, porting additional iOS apps to macOS and overhauling some existing apps. There are new Music, Books, and Podcasts app, with the iTunes app being retired.

Apple is also making it possible for developers to bring their iPad apps to the Mac with just simple changes, which will make it simple for developers to create cross-platform content while also increasing the number of available Mac apps.

You're able to use the iPad as an external display thanks to new continuity functionality built into macOS Catalina and iOS 13, and there's a new "Find My" feature for locating lost devices and friends even when your devices have no cellular or WiFi connection.

macOS Catalina is only available to registered developers at this time, but later in the summer, Apple plans to make a public macOS Catalina beta available, giving public beta testers a chance to try the software before it sees a public launch in the fall.

I just started installing my beta update and will be ready to start playing around in about 8 minutes! I'm excited.

To make the bootable usb installer, once downloaded to the Applications folder format a 16GB USB as HFS+ Journaled, call it Untitled and run this command in Terminal:

sudo /Applications/Install\ macOS\ 10.15\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

You can then boot up with option key and select the bootable usb.

Good ! Should have ended years ago :)!
Yes but you would be surprised how many bits and pieces of apps you use that have left over 32 bit code that will hold up the app waiting for updates. Look at the list in your mac of 32 bit apps. Even 64 bit apps can have little bits of code like update checkers etc that will probably just kill the app entirely. Most will eventually get fixed but plenty will not

I wonder if they will support external HDR monitors. I see it states 2018 or later for HDR content!

We were in the process of building the next major version of Awaken for iOS and macOS. We're going to try using Project Catalyst for this now. Should be interesting :). If anyone would like to beta test - email: support@embraceware.com.
