Apple today seeded the fourth beta of an upcoming macOS Catalina 10.15.2 update to developers, two weeks after releasing the third beta and over a month after the launch of macOS Catalina 10.15.1.

The new macOS Catalina beta can be downloaded through the Software Update mechanism in the System Preferences app after installing the appropriate profile from the Developer Center.

We don't yet know what improvements the second update to macOS Catalina will bring, but it most likely focuses on performance improvements, security updates, and fixes for bugs that weren't able to be addressed in the macOS Catalina 10.15.1 update.

We didn't find any major new changes worth noting in the first three betas, but we'll update this article should anything notable be found in the fourth beta.

macOS Catalina is a major update that does away with iTunes in favor of new Music, Podcasts, and TV apps. It also nixes support for 32-bit apps, adds a new Find My app, brings a new Photos interface, and includes multiple privacy enhancements and other app refinements.

Anyone who follows the beta cycles have an educated guess when this will be released?


Around January

no, 10.15.2 will be out around January.
What makes you so confident it'll be released in January? I would have guessed it might release as soon as next week, but it's a total guess on my part. The new 16" MBP (a halo product along with the new Mac Pro) is experiencing some glitches which I surmise might be fixed or at least improved in 10.15.2, so there's incentive for Apple to get the .2 update in a timely manner.

Given the complaints and reviews on Apple Store, this software is probably the worst performing operating system ever introduced by Apple. I cannot believe how slow Apple have been at providing ‘fixes’.

I myself have sent through multiple Feedback reports and nothing. Problems that still exist from PB 3!

Hopefully they fix syncing for photos for albums in folders. They had this same bug several major releases ago and it is back. (People aren't happy if OS's aren't well tested.)

This isn't the worst ever - that medal gets pinned on Lion. Catalina is definitely second though. I just gave up ruining my life beta testing this one. I swore I wouldn't touch this pox ridden OS X version until at least 10.15.4, but then I went ahead and purchased a new 16" MacBook Pro so now swimming nose deep in hot, steaming [censored] along with the rest of the Catalina crowd...
Catalina is not Apples best macOS* ;) , but it's by no means the worst or second worst OS, seems like you and others haven't been using OS X/macOS long enough.
For me Yosemite sucked, but just for one single reason and it was a problem lots of people had, Google Yosemite Wifi problems, it took Apple 6-8 months to completely get rid of Wifi problems.
Mojave was by far Apples best OS, stable right from the first beta, no other beta or even a release was that stable, not even the Snow Leopard came close, especially not in the first few .X releases.
Some of the early OS X versions lacked a lot of features, it wasn't until Tiger before it became good.


*= Catalina is macOS, not OS X
