Apple has released new minor updates for iOS 16, macOS 13 Ventura, and most of its other actively supported operating systems that fix a pair of serious security bugs that the company says "may have been actively exploited." You should install the iOS and iPadOS 16.5.1, macOS 13.4.1, and watchOS 9.5.2 updates at your earliest convenience, if you haven't already.
