Some users have reported being doubly affected, facing severe issues on both their iPhone and Apple Watch following the updates.

This removal of beta versions reflects Apple's response to user feedback and the technical issues encountered after the updates were released.

Users experiencing boot looping are currently unable to use their devices, and there is no confirmed timeline for when Apple will issue a fix.

The iOS 18.4 beta 1 introduced new features like a 'Sketch' drawing style but did not include anticipated enhancements such as visual intelligence for the iPhone 15 Pro and personal Siri.

This information was reported by Aaron Perris on X, highlighting the unsigned status of the beta.

Apple has decided to pull the latest beta updates for iOS 18.4, iPadOS 18.4, and watchOS 11.4 due to significant issues, including boot looping on several devices.

The affected iOS devices include the iPhone 12 Pro, iPhone 12 Pro Max, iPhone 12 mini, along with various models of the iPad Air and iPad 8.

In addition to the watchOS issues, Apple has also unsigned the iOS and iPadOS 18.4 beta 1 for select iPhones and iPads.

Boot looping is a problem where a device fails to complete the boot process, resulting in continuous restarts, and has been a recurring issue during beta releases.

The watchOS 11.4 beta was released on February 21, 2025, alongside the iOS 18.4 beta and visionOS 2.4 beta.

The decision to withdraw the beta updates was influenced by reports from users on the r/watchOSbeta subreddit who experienced problems after installation.

The affected Apple Watch models include all variants of the Series 6, both GPS and GPS + Cellular, in 40mm and 44mm sizes.
