Apple's first developer betas for its fall OS updates have arrived

By Malcolm Owen

Apple has made the first developer betas for its fall operating systems available, with new builds of iOS 18, iPadOS 18, tvOS 18, watchOS 11, and macOS Sequoia open to download.

Developers can start to try out Apple's new betas.

The WWDC keynote introduces changes to Apple's operating systems that will be arriving in the fall, or soon after. As usual, shortly after their introduction in the keynote, Apple has made the betas available to download via its developer beta program.

The betas are for iOS 18, iPadOS 18, watchOS 11, tvOS 18, and macOS Sequoia. This now means Apple is running two beta tracks, with 17-generation operating system updates being tested at the same time.

The first developer betas of iOS and iPadOS 18 are build number 22A5282m, while the first tvOS 18 build number is 22J5290l. The first watchOS 11 developer beta is 22R5284o, and the first macOS 15 Sequoia developer beta build is number 24A5264n.

AppleInsider and Apple strongly suggest users don't install 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.
