This update introduced over 70 new emoji characters to the Mac ecosystem.
This update was designed for all Macs that could run macOS High Sierra. Officially, that included the following models: macos high sierra 10.13.1
The single most significant security fix in macOS High Sierra 10.13.1 was the patch for the KRACK (Key Reinstallation Attack) vulnerability. This was a severe security flaw that allowed attackers to potentially intercept and decrypt data transmitted over Wi-Fi networks protected by the WPA2 protocol. By exploiting the KRACK vulnerability, a malicious actor within range could theoretically eavesdrop on network traffic, capturing sensitive passwords and information. Apple patched this critical security gap on the macOS side with the 10.13.1 update, ensuring users were protected when connecting to secure Wi-Fi networks.
