Apple gave both developers and the public access to the release candidates of macOS Monterey 12.4 and iOS 15.5 on Thursday. The iPadOS 15.5 Release Candidate also went out, as did the watchOS 8.6 RC and tvOS 15.5 RC. That’s the final step before introducing them to the public.
Aside from long-overdue improvements to the Studio Display webcam in macOS, all these are really just minor tweaks. But that’s not surprising considering Apple is expected to unveil the next major upgrades for the OSs at WWDC22 in early June.
