Apple has introduced a new system for distributing beta software with iOS 16.4, which now checks whether the user’s Apple ID is participating in the Apple Developer Program or the Apple Beta Software Program. This system is now being expanded to the Mac and Apple Watch with macOS Ventura 13.4 and watchOS 9.5.
Apple is changing how users and developers install beta software on macOS and watchOS
As noted by 9to5Mac, both operating systems now ask for the Apple ID to show and download operating system beta updates. Just like in iOS 16.4 and later, the system checks whether the account is associated with a developer or user registered in the public beta program. It then shows the beta update available for that program.
Previously, anyone could install betas of iOS, macOS, and watchOS by having the right beta profile. But with this change, regular users will no longer be able to install developer betas, for example. Users who are not registered for the program will only have the option of installing public beta software.
