Apple has made its fourth beta iteration of watchOS 11.5, tvOS 18.5, and visionOS 2.5 available to testers and developers.
The fourth beta updates launched just a week after Apple provided the third betas for testing purposes. It’s worth noting that in order to access the beta software updates, you’ll need to be a registered developer. The fourth beta and other beta versions are usually downloaded on the device within the Settings section. Developers will also need a registered Apple ID in order to get inside the software and test it.

watchOS is for the Apple Watch, while tvOS is for the Apple TV set-top boxes. visionOS is for the Apple Vision headset. The fourth beta does not have new or notable features; it’s believed to contain various bug fixes and performance improvements. Apple is expected to unveil watchOS 12, tvOS 19, and visionOS 3 during this year’s WWDC.
