Yesterday, macOS High Sierra beta 4; today the iOS 11.2 (build 15C5110b), the watchOS 4.2 (15S5102b) and the tvOS 11.2 (15K102a). Apple isn't really kidding, releasing new test versions of its operating systems as soon as it thinks it's interesting even if it's only a few days later, since the third versions came out last Monday (11/13).
No major news is expected in these versions other than those already commented by us, such as new wallpapers, compatibility with faster wireless recharge, Apple Pay Cash, news in the Control Center, among other things.
Soon, all of these systems (with the exception of watchOS) will be available for testing also in the Apple Beta Software Program. As always, if anything new comes out of the above, we will update this article. ?
