Apple rolls out the first developer betas of iOS 27, iPadOS 27, watchOS 27, macOS 27, and more

Apple has started rolling out the first betas of the newly announced iOS 27, iPadOS 27, macOS Tahoe 27, watchOS 27, tvOS 27, and visionOS 27 to developers. These updates include improvements to Liquid Glass, a new Siri AI, new Screen Time options, and more, announced at today’s WWDC event.

Here are the build numbers for the new developer betas:

• iOS 27.0 and iPadOS 27.0 Beta 1: 24A5355q
• macOS Tahoe 27.0 Beta 1: 26A5353q
• watchOS 27.0 Beta 1: 24R5289n
• visionOS 26.6 Beta 1: 24M5291p
• tvOS 26.6 Beta 1: 24J5289o

Usually, as we progress through the beta cycle, the letter at the end of a build number is in descending order. The letters ‘q’, ‘p’, ‘n’, and ‘o’  towards the end of the build number indicate that we have several more beta versions before the Release Candidate, which is expected to be released in September before the new iPhones are announced We can expect the next betas for version 27.0 to be rolled out after 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.

Do note that these versions are not stable and are meant for testing purposes. They are not recommended to be downloaded on a primary device due to the nature of beta software.
