Holiday or not, Apple doesn’t care and is delivering a new batch of security updates for old iPhones, iPads and Macs tonight! This is’iOS 15.7.5, iPadOS 15.7.5of macOS Big Sur 11.7.6 and of macOS Monterey 12.6.5. These are software to be installed once more since they plug very serious “zero day” security flaws. Apple indicates that they may have been actively exploited.
Two very serious security flaws have been fixed in macOS 13.3.1 and iOS 16.4.1
These vulnerabilities were fixed last Friday for devices compatible with iOS 16, and with Macs compatible with macOS Ventura. In any case, you should download these updates and install them as soon as possible.
