Apple’s first developer betas for iOS 27, iPadOS 27, and macOS 27 are now available for testing. Apple posted the releases on its developer software releases page on June 8. That gives app makers and early testers their first hands-on look at the next major platform cycle.
Apple labels the first iOS 27 and iPadOS 27 developer betas as build 24A5355q. The first macOS 27 beta carries build 26A5353q. Apple also posted Xcode 27 beta, plus first beta builds for tvOS 27, visionOS 27, and watchOS 27.
What developers can test now
For developers, this is where the fall software story moves from keynote slides to real compatibility work. Developers can test apps against new SDKs, system behavior, and interface changes before the updates reach everyday users later this year.
Apple’s OS overview page says iOS 27, iPadOS 27, macOS 27, watchOS 27, and visionOS 27 are coming this fall. The company points to Siri AI, expanded Apple Intelligence, Visual Intelligence on more devices, child safety improvements, and broader OS refinements.
Public beta users still have to wait
This is not the same as the public beta. Apple’s Beta Software Program page says new public betas for iOS 27, iPadOS 27, macOS Golden Gate, tvOS 27, HomePod software 27, watchOS 27, and AirPods Firmware are coming soon.
That gap matters. Developer betas are useful for testing, but they can still carry bugs, battery issues, broken app behavior, and unfinished features. Most readers should wait for the public beta or the final fall release unless they have a spare device.
The iPhone question is already important
Device support will be one of the first things many readers check. Tech My Money has already covered how iOS 27 compatibility appears to extend support to the iPhone 11. That could make this year’s update feel less punishing for people holding older hardware.
For now, the safest takeaway is simple. The developer track is open, public testing is not here yet, and the first real wave of feedback should start as developers install the new builds.
