Apple recently pushed the third developer beta version of a new round of 27 series operating systems to developers, including iOS 27, iPadOS 27, macOS 27, tvOS 27, watchOS 27 and visionOS 27, and continues to prepare for the official version for the public this fall. The new version comes not long after the second round of developer betas: the second beta was released on June 22 for most systems, and watchOS 27 beta 2 was launched on June 23 and June 25 respectively.
The specific version numbers of each platform system in the third round include: iOS 27 Developer Beta 3 version number is 24A5380h, replacing the previous 24A5370h; iPadOS 27 Developer Beta 3 version number is also 24A5380h, replacing 24A5370h; macOS 27 Developer Beta 3 version number is 26A5378j, replacing 26A5368g; tvOS 27 Developer Beta 3 is 24J5315i, replacing 24J5305f; watchOS 27 Developer Beta 3 is 24R5315i, replacing 24R5305g; visionOS 27 Developer Beta 3 is 24M5316k, replacing 24M5306i.
Apple opened the first developer test versions of iOS 27, iPadOS 27, macOS 27, tvOS 27, visionOS 27 and watchOS 27 to developers for the first time on June 8, kicking off the overall iteration of the 27th generation system. The first releases have introduced changes including Liquid Glass tweaks, a major revamp of Siri, child protection optimizations, and many other detailed system-level updates. The second iOS 27 developer beta continues to improve features on this basis, such as displaying Apple TV devices in a form similar to HomePod or HomePod mini in the Home App, and adding "Insights" options in Apple Wallet that are not yet fully available.
Apple is still emphasizing that these early developer beta versions are mainly for developers and testers so that they can fully understand and adapt to system-level changes before the final official version is released, and are not designed for daily use by ordinary users. Since the system is still in the active development stage, the probability of bugs, functional anomalies and even potentially destructive problems in early test versions is significantly higher than in the official version. Therefore, the test environment should try to use backup devices instead of personal main devices. Unless users have clear needs in application development, etc., it is not recommended to install such early developer beta versions.
For ordinary users who are interested in experiencing the new system features, it is recommended to wait for the public beta version that Apple will subsequently launch. By then, with multiple rounds of developer beta iterations, most serious problems have usually been discovered and fixed, and overall stability will be significantly improved. Prior to this, Apple and the media have repeatedly reminded users that rashly installing early beta versions without adequate backup and risk awareness may encounter problems such as data loss and device abnormalities.
