Apple has today seeded the latest in a growing line of macOS 10.15 Catalina betas to developers. The new beta, the fourth to be released, is available for registered developers right now and comes two weeks after the third beta was released.
Those who are registered developers and have macOS 10.15 Catalina installed can download the update now via the System Update area of System Preferences.
Anyone installing afresh will need to download the configuration app from the Apple developer portal. As always, these betas should not be installed on a user’s main device given their beta status.
While a lot of the focus is on iOS 13 and iPadOS 13 this year, macOS 10.15 Catalina stands to be one of the biggest updates to the Mac in some time. New apps like Music, Podcasts, and TV will replace the ageing iTunes while new Sidecar feature will allow iPads to be used as secondary monitors, too.
Apple is also finally bringing Screen Time to the Mac, with a new Photos interface also mimicking that which will arrive on iPhones and iPads this year. That change allows for the easier surfacing of photos from large libraries and looks set to be a big improvement over previous Photos releases.
If past release cadences are to be believed we can expect Apple to make macOS 10.15 Catalina available to the public around September time, alongside new releases of iOS, iPadOS, watchOS, and tvOS. We also expect new iPhones and a possibly new Apple Watch and iPad releases around that time of the year, too.
