Apple just released the new beta version for macOS High Sierra for developers, a little less than a week after launching the 3rd version of macOS 10.13.1, and a month after launching this new operating system, High Sierra.
It is mainly focused on the correction of some errors discovered in previous versions, various performance enhancements, security enhancements, and other changes to provide stability and improve the product.
This includes a Fix for a recent critical vulnerability in the WPA2 Wi-Fi standard, thanks to which many modern Wi-Fi networks are protected.
Using a key reinstall attack or "KRACK", Attackers could exploit weaknesses in the WPA2 protocol to decrypt network traffic and detect sensitive information. This attack would no longer be possible with the patch built into macOS 10.13.1.
The update also brings a new range of Unicode 10 emojis, like crazy face, cake, pretzel, t-rex dinosaur, vampire, exploding head, new vomiting face, new quiet face, new brain, scarves, and different animals, like new zebra, a hedgehog or giraffe, as well as a fortune cookie, a new cake, and more. The new emoji are also available in iOS 11.1 and watchOS 4.1.
The fourth beta of macOS High Sierra 10.13.1 can be downloaded from the Apple Developer Center or through the software update mechanism in the Mac App Store; yes, with the appropriate profile installed.
