Apple today seeded the fourth beta of an upcoming macOS Catalina update to its public beta testing group, two weeks after seeding the third public beta and a day after seeding the fifth macOS Catalina developer beta.
Beta testers who have signed up for Apple's beta testing program will be able to download the macOS Catalina beta through the Software Update mechanism in System Preferences after installing the proper profile. Those who want to be a part of Apple's beta testing program can sign up to participate through the beta testing website, which gives users access to iOS, macOS, and tvOS betas.
Potential beta testers should make a full Time Machine backup before installing macOS Catalina, and it may not be wise to install it on a primary machine because betas can be unstable and often have many bugs.
macOS Catalina eliminates the iTunes app, which has been a key Mac feature since 2001. In Catalina, iTunes has been replaced by Music, Podcasts, and TV apps. The new apps can do everything that iTunes can do, so Mac users aren't going to be losing any functionality, and device management capabilities are now handled by the Finder app.
macOS Catalina has a useful new Sidecar feature, designed to turn the iPad into a secondary display for the Mac. It can work as a traditional second display or with a mirroring feature. Apple Pencil support works with Sidecar, so you can turn your iPad into a drawing tablet using apps like Photoshop.
For those with an Apple Watch set up to unlock the Mac, there's now an option to approve security prompts in Catalina by tapping on the side button of the watch. Macs with a T2 chip in them also support Activation Lock, making them useless to thieves much as it does on the iPhone.
There's a new Find My app that lets you track your lost devices, and previously, this functionality was only available via iCloud on the Mac. There's even a new option to find your devices even when they're offline by leveraging Bluetooth connections to other nearby devices, something that's particularly handy on the Mac because it doesn't have a cellular connection.
Apple is expanding Screen Time to the Mac in Catalina, letting Apple users track their device usage across Mac, iOS, and iPad for a better overall picture of time spent using electronics.
For developers, a "Project Catalyst" feature lets apps designed for the iPad be ported over to the Mac with just a few clicks in Xcode and some minor tweaks. Apple's ultimate goal with Project Catalyst is to bring more apps to the Mac.
Photos features an updated interface that better highlights your best pictures, Safari includes a new start page with Siri Suggestions, Mail has a new feature for blocking emails and another new option for muting threads, and the Reminders app has been overhauled and is now more useful.
Before installing macOS Catalina, be aware that it does not support 32-bit apps, so some older apps that have not been updated in some time may stop working. For more on macOS Catalina, make sure to check out our macOS Catalina roundup.

If you go to beta.apple.com, login and then attempt to download the "Public Beta Access Utility", the link is pointing to this right now:
https://beta.apple.com/sp/downloads/projects/1001260/downloads/1010768
Clicking that link will download a DMG file. Double-click on the DMG file to mount the virtual volume. If you "get info" on the package inside this volume, you'll discover it was last modified on 05/30/18 -- yes, not 2019. If you install the package, it will set your Software Update catalog to this (I substituted https:// with XXXXX at the beginning because this editor keeps turning it into a hotlink if I leave it there):
[B]XXXXXswscan.apple.com/content/catalogs/others/index-10.14beta-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog.gz[/B]
Yes, this is the enrollment tool for the Mojave beta, not the Catalina beta. Oops! Want proof? Launch Terminal and execute this command to see where your Software Update is now pointed:
sudo defaults read /Library/Preferences/com.apple.SoftwareUpdate CatalogURL
You should see that "10.14beta" in the reply string.
Even though this installer is obsolete, you should still run it because it will create the SeedEnrollment file you need. Software Update will then check for updates and discover the "requested version of macOS is not available" since it's looking for the Mojave beta.
Once you receive that message, execute this command in Terminal to fix the the catalog location (again, where you see XXXXX substitute https:// because this board keeps trying to put a hotlink in the middle of my text!):
sudo /usr/sbin/softwareupdate --set-catalog XXXXXswscan.apple.com/content/catalogs/others/index-10.15beta-10.15-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog.gz
Check for updates again and you should now see the Catalina beta is available.
HOWEVER: for me, at least, all this did was allow me to download the latest beta installer onto my MacBook Pro (15-inch, 2019). I tried using it to make a bootable USB installer disk so I could do a complete clean install -- booting on this USB drive still produces the error message about needing to update my installer disk. I can see it's attempting to download what it needs to update my disk but it fails halfway through.
I submitted a report through the Feedback Assistant for both of these issues. Of course, I'm just one of the horde who's sending feedback about the beta. Anyone with a bonafide connection to Apple may want to drop them a line that their beta enrollment tool has been incorrectly downgraded.
As for the other issue, I wish someone would figure that out so I can actually use the new computer I just bought. :(
