Release Candidates for iOS 17.3, iPadOS 17.3, macOS Sonoma 14.3, Available for Testing

Apple has issued Release Candidate builds for iOS 17.3, iPadOS 17.3, macOS Sonoma 14.3, watchOS 10.3, and tvOS 17.3, for users involved in the beta testing programs.

Release Candidate (RC) builds are typically the final version of a beta release cycle before the update becomes broadly available to all users. Occasionally, a second (or even third) RC build is released, if some notable bug or security issue is addressed.

The final versions of iOS 17.3, ipadOS 17.3, and macOS Sonoma 14.3 will be released next Tuesday, on January 23, according to Apple.

The most significant new feature included in iOS 17.3 is Stolen Device Protection, which intends to make it more difficult for a thief who knows a device passcode to cause problems or turn off Find My / Lost Mode, by requiring Face ID or Touch ID in addition to the passcode before certain changes can be made on the device. Obviously this requires the usage of Face ID or Touch ID on the device in question.

Another smaller new feature available for iOS 17.3, ipadOS 17.3, and macOS 14.3, is the ability to collaborate on Apple Music playlists, and to use Emoji reactions in those playlists.

iOS 17.3 also gains a new Black Unity wallpaper to celebrate Black culture and Black History Month, and the ability to more easily stream AirPlay content in hotel rooms.
