Apple Stops Signing iOS 16.3.1 to Prevent Downgrading
Following the release of iOS 16.4.1 today, Apple has stopped signing iOS 16.3.1, preventing iPhone users from downgrading to that software version. iOS 16.4, iOS 16.4.1, and the iOS 16.5 beta remain signed at the time of writing.
iOS 16.3.1 was released on February 13 and was a minor update with bug fixes, security improvements, and additional Crash Detection optimizations for iPhone 14 models. Apple routinely stops signing older iOS releases over time in order to prevent users from downgrading to an outdated software version.
iOS 16.4 will likely be unsigned later this month, so iPhone users who wish to downgrade to that version have limited time remaining to do so.
Today apple unsigned: iOS 16.3.1

regarding macOS mavericks, absolutely - that is a solid macOS version. however i honestly can’t really agree with your implication that ios 6 was good - for the time it absolutely was. but ios has matured a lot since then, and is a much better mobile operating system now than it was back then.
