Apple has taken another step towards the release of its next-generation operating systems by issuing the first public beta builds of iOS 18, iPadOS 18, macOS 15 Sequoia, tvOS 18, and HomePod Software 18. Interested users can sign up for Apple's public beta program with their Apple ID and select the public beta builds from the Software Update in the Settings app.

These releases were initially announced during Apple's Worldwide Developers Conference in June, with highlights including enhanced home screen customization for iOS and iPadOS, window tiling and iPhone mirroring for macOS, RCS text messaging support across all platforms, and more. However, Apple has not yet showcased its Apple Intelligence AI features, which include text and image generation features and a revamped Siri. These features are expected to be unveiled later this summer and will likely be incorporated into the final releases in the fall.

Most devices that currently run iOS 17, iPadOS 17, and macOS 14 Sonoma will be able to update to the new versions, including the recent generations of Intel Macs. However, a few older phones, tablets, and the 2018 MacBook Air will not be compatible with the new releases. In addition, the watchOS 11 update will no longer support the Series 4 and Series 5 models, as well as the first-generation Apple Watch SE.

Unfortunately, there will not be a public beta build for VisionOS 2, the first major update to the Apple Vision Pro's operating system. Users interested in trying out the new Vision Pro features ahead of time will need to opt into the developer beta for now.

Despite three beta releases, iOS 18 testers are still unable to experience the Apple Intelligence features. The first public betas are similar, if not identical, to the third developer beta builds released last week. It is anticipated that a fourth developer beta will be released early next week, followed by a second near-identical public beta build.

Previously, Apple's developer and public beta builds were separated by a paywall, requiring a $99-per-year developer account. However, Apple made basic developer accounts and beta software access free for all users last year. Although developer betas are rougher and visibly unfinished, public betas are also unfinished and potentially unstable. Nevertheless, users can expect most basic functionality to work fine.

As always, it is advisable to create a backup of the device before updating, in case it is necessary to restore the older, more stable operating system. It is also recommended not to install beta software on mission-critical hardware that is crucial for day-to-day activities. For iPhone and iPad users who connect to iCloud, performing a local backup via a PC or Mac, preferably an encrypted one, is a more reliable method of ensuring a pre-upgrade backup is available, rather than relying solely on continuous iCloud backups.
