iOS 18.6 second beta released on June 30, 2025

Examples of Apple Intelligence at work.

Apple is now on its second round of betas for its current-gen testing track, with new builds of iOS 18.6, iPadOS 18.6, macOS 15.6, watchOS 11.6, tvOS 18.6, and visionOS 2.6 now available for testing.

The second iOS 18.6 and iPadOS 18.6 developer betas have build number 22G5064d, replacing the first, 22G5054d. The second macOS Sequoia 15.6 build is 24G5065c, up from 24G5054d.

The second tvOS 18.6 build is 22M5065b and replaces 22M5054b, the second watchOS 11.6 build is 22U5065c taking over from 22U5054b, and the second visionOS 2.6 build is 22O5764b, up from 22O5754c.

This is a second beta-testing track for Apple, running alongside a milestone update version, which is putting iOS 26, iPadOS 26, macOS 26, watchOS 26, tvOS 26, and visionOS 26 through their paces.

The content of these developer betas are minimal, in part because the focus is on new features in the fall software releases. However, they are likely to include performance and security updates as usual.

AppleInsider and Apple itself strongly advise that users do not install beta operating systems or other software being tested on what they consider “mission-critical” or primary hardware, due to the ever-present danger of bugs and issues that could result in the loss of data. As always recommended, testers should use secondary or non-essential devices, and to make sure there are sufficient backups available of their data.
