Apple seeds fourth developer betas of iOS 18, iPadOS 18, tvOS 18, watchOS 11, visionOS 2

Apple's now on its fourth round of developer betas for its fall operating system updates, with new builds of iOS 18, iPadOS 18, tvOS 18, macOS Sequoia, watchOS 11, and visionOS 2 now available

Round four arrives after an unusual third round. After the initial release on July 8, July 10 for macOS Sequoia, Apple then reissued the betas for iOS 18, iPadOS 18, and macOS Sequoia on July 15.

The betas are for iOS 18, iPadOS 18, watchOS 11, tvOS 18, and macOS Sequoia, as well as visionOS 2. Apple is also operating developer betas for its current generation of operating systems, including iOS 17.5 and so forth.

The fourth developer betas of iOS and iPadOS 18 are build number 22A5316j replacing the third, 22a5307i. Apple's fourth tvOS 18 build number is 22J5424f up from the third, 22J5315e.

The fourth macOS 15 Sequoia beta is build number 24A5298h, replacing the reissued third build, number 24A5289h. The fourth watchOS 11 developer beta is 22R5318h taking over from 22R5309f.

The fourth visionOS 2.0 developer beta is build 22N5286g while the third was 22N5277g.

The third round of developer betas for iOS 18 had changes to dark mode for icons, updates to the flashlight controls, and hints to a new home device.

The second included SharePlay upgrades and iPhone Screen Mirroring, which Apple confirmed days before issuing.

The confirmation was part of Apple's response to stories that it may abstain from offering Apple Intelligence and other major new operating system features in the European Union, due to Digital Markets Act interoperability mandates.

AppleInsider and Apple strongly recommend that users avoid installing test operating systems or other beta or RC software on "mission-critical" or primary devices, as there is the small chance of issues that could result in the loss of data. Testers should instead use secondary or non-essential hardware and ensure they have sufficient backups of their critical data at all times.
