Apple has released the fourth public betas of macOS Sonoma 14, iOS 17, iPadOS 17, tvOS 17, and watchOS 10. Public betas are available on Apple’s Beta Software Program website.
Just remember that beta software is unfinished software, so proceed with care. Apple does public betas in order to increase the size of the pool of testers. The tech giant recommends keeping back-ups of your files before installing a public beta.
