Apple rolls out the second developer betas of iOS 26.6, iPadOS 26.6, watchOS 26.6, and more

Apple has started rolling out the second betas of iOS 26.6, iPadOS 26.6, macOS Tahoe 26.6, watchOS 26.6, tvOS 26.6, and visionOS 26.6 to developers. These updates come three weeks after the release of the first betas for these versions, and one week after the release of iOS 27.0 Beta 1. With the release of the first beta, iOS 26.6 introduced a new alert or warning when a user tries to exceed the limit of blocked contacts.

Here are the build numbers for the new developer betas:

• iOS 26.6 and iPadOS 26.6 Beta 1: 23G5043d
• macOS Tahoe 26.6 Beta 1: 25G5043d
• watchOS 26.6 Beta 1: 23U5040d
• visionOS 26.6 Beta 1: 23O5743c
• tvOS 26.6 Beta 1: 23L5744d

Usually, as we progress through the beta cycle, the letter at the end of a build number is in descending order. The letters ‘c’ and ‘d’ towards the end of the build number indicate that we might have 3-4 more beta versions before the Release Candidate. There are no new major AI features in versions 26.6; however, Apple has introduced an even smarter Siri with Personal Context, new Photo Editing options, Agentic Password updating, improved Image Playground, and more in versions 27 on devices that support Apple Intelligence. iOS 26.6 is one of the last major versions of iOS 26, as Apple is currently focusing on iOS 27. We can expect the next betas for version 26.6 to be rolled out after 1-2 weeks. Users who are registered as a developer on www.developer.apple.com can opt in to receive beta updates by going into Settings>General>Software Update>Beta Updates and selecting Developer Beta.
