Apple has seeded the third public betas of both macOS Catalina and tvOS 13 to public testers.

Back at the end of June, Apple seeded the first public betas of its most popular operating systems, and now the company is moving forward with the newest versions. On Thursday, Apple seeded the third public betas of macOS Catalina and tvOS 13. If you are not already part of the public beta program, you can sign up right here.

macOS Catalina is a major update for Apple and its desktop operating system, bringing with it a variety of new features. That includes a break up of the standard iTunes software, opting to launch three separate apps in its wake: Apple Podcasts, Apple Music, and Apple TV. Apple has already detailed the major changes related to this, which we’ve outlined here.

As is par for the course, with any first beta of any software, it’s definitely possible that the release has a variety of bugs and other issues that can plague performance. So if you do plan on trying the new software out, be aware of the potential issues.

As far as what’s new, there’s quite a bit in addition to what’s mentioned above. That includes a new Sidecar feature, which will allow macOS Catalina users to utilize their iPad as a secondary display. An Apple Watch will have additional authentication abilities with macOS Catalina as well, and the new Find My app will help folks find a lost Mac — even when it’s not on and running.

tvOS 13 doesn’t have as many new features as iOS 13 or macOS Catalina, but there are some big new additions. That includes a new multi-user support, allowing for multiple people to have their own profiles on a single Apple TV. This will offer up personalized content as they sign in, and even give them access to their own Apple Music profiles as well (if they have one).

tvOS 13 also offers a new Home screen, which Apple says should make it easier to find content. The new software also supports Apple Arcade, Apple’s subscription service to download and play games across tvOS, iOS, iPadOS, and macOS, all for a single monthly subscription.
