Apple's testing of Apple Intelligence continues, with the sixth developer betas of iOS 18.1, iPadOS 18.1, and macOS Sequoia 15.1 now available.
Examples of Apple Intelligence at work.
The sixth developer betas of iOS 18.1, iPadOS 18.1, and macOS Sequoia 15.1, arrive after the third builds of visionOS 2.1, tvOS 18.1, and watchOS 11.1, which arrived on October 1. The respective fifth and second builds landed on September 23, while the fourth and first respective builds were introduced on September 17.
The difference in build counts is due to Apple beta testing tvOS 18, watchOS 11, and visionOS 2 at the same time as the Apple Intelligence-infused iOS 18.1, iPadOS 18.1, and macOS Sequoia 15.1.
The new iOS 18.1 and iPadOS 18.1 build numbers are 22B5069a and 22B5069a, while macOS Sequoia has moved on to build 24B5070a.
The main difference between the iOS 18.1 and 18 operating system versions is Apple Intelligence, which includes generative AI and machine learning features. Not all Apple Intelligence features will be available when it is eventually released.
Early Apple Intelligence features that appeared included a new Siri animation, Type to Siri, a better understanding of queries and contextual awareness, product knowledge, and a swathe of writing tools.
The third developer beta brought with it Clean Up for Photos, which lets users remove unwanted elements from images.
In the fifth build, Apple's iOS 18.1 changes were largely nothing to do with Apple Intelligence. The changes included enabling file drag and drop with the iPhone Mirroring feature of macOS, a new selfie option for Camera Control, and adjustments to Control Center.
AppleInsider and Apple strongly advise that users do not install test operating systems or other beta or RC software onto "mission-critical" or primary hardware, due to the small chance of issues that could result in the loss of data. Testers should therefore use secondary or non-essential devices and make sure they have sufficient backups of any critical data.
