Apple will roll out its latest operating systems, including iOS 26 and macOS Tahoe, on September 15. The update arrives just before the launch of the iPhone 17, Apple Watch refreshes, and AirPods Pro 3.
Unified Version Numbers
For the first time, Apple is aligning version numbers across all platforms. iOS, iPadOS, macOS, watchOS, visionOS, and tvOS will now share the same number: 26. This change reduces confusion for users and developers, creating a more consistent ecosystem.

Introducing Liquid Glass
The highlight of the updates is a new design called Liquid Glass. It brings transparency and light refraction effects to the interface, giving Apple devices a sleek and modern look. Apple also refined many first-party apps to make them simpler and more enjoyable to use.
Testing and Availability
Developers and public beta testers have tried these updates since WWDC. Their feedback helped Apple fine-tune the final release, which is now ready for global distribution.
Looking Ahead
By unifying version numbers and introducing Liquid Glass, Apple is pushing for greater consistency across its ecosystem. The September 15 release prepares users for a more polished experience, just in time for new hardware.
