Apple finally seeded to developers iOS 16.4 beta 1 and macOS 13.3 beta 1 on Thursday, followed by releasing public beta versions on Friday. The same goes for the initial betas of iPadOS 16.4, watchOS 9.4 and tvOS 16.4.
The wait for new betas has been much longer than usual. The last round of new prerelease versions was in mid-January.
The new betas bring in a collection of new emoji, an improvement for Apple Pencil, a better way for devs to work with betas, and more changes.
