Apple's second beta track for fall releases with Apple Intelligence is in its second round, with new builds of iOS 18.1, iPadOS 18.1, and macOS Sequoia 15.1 now available for developer testing.
Apple has released the first round of beta versions July 29.
The second iOS 18.1 and iPadOS 18.1 build number is 22B5023e, replacing 22B5007p. The second macOS Sequoia 15.1 build number is 24B5024e, up from 24B5009l.
The main difference between versions 18.1 and 18 is Apple Intelligence, the Cupertino giant’s push to offer generative AI and machine learning to its users. Only a few of the features are available for testing in this version.
What has come to the surface is, among other things, a new Siri animation, Type to Siri, better question understanding and contextual awareness, product knowledge, and a range of writing tools.
For the fifth developer beta With iOS 18, Apple introduced Distraction Control, a feature for Safari that removes unwanted elements from web pages. It also made changes to the Photos app, updating the user interface to remove the Carousel, among other changes.
While it's too early to tell, it's highly likely that Apple has rolled these changes from the iOS 18 beta into the 18.1 variants.
AppleInsider and Apple highly recommended that users avoid installing test operating systems or other beta or RC software on “mission-critical” or primary devices, as there is a small chance of problems that could lead to data loss. Testers should instead use secondary or non-critical hardware and ensure that they have adequate backups of their critical data at all times.
