Apple has officially kicked off the 26.4 beta cycle, and it’s a full lineup this time.
Developer beta 1 is now available for:
- iOS 26.4
- iPadOS 26.4
- macOS Tahoe 26.4
- watchOS 26.4
- tvOS 26.4
- visionOS 26.4
- HomePod 26.4
Public beta testers will likely get access within the next week.
This wave comes just days after Apple shipped the 26.3 updates, which were mostly focused on bug fixes and security patches. The 26.4 cycle, however, is expected to be more interesting.
The big question mark is Siri. Apple’s long-promised AI revamp is now expected to roll out in stages, potentially beginning with 26.4. Whether that means meaningful new capabilities right away or just groundwork for bigger changes later remains to be seen.
Beyond Siri, these updates could include performance optimizations and under-the-hood improvements ahead of upcoming hardware launches. With new Macs, iPads, and possibly iPhone 17e rumored for early March, it would not be surprising if 26.4 quietly prepares the stage.
If you’re a developer, you can download the betas now via Settings > General > Software Update on supported devices.
