Apple today released macOS Monterey 12.2.1, a minor bug fix update that comes two weeks after the launch of macOS Monterey 12.2.

The ‌‌‌‌macOS Monterey‌ 12.2.1‌‌ update can be downloaded on all eligible Macs using the Software Update section of System Preferences.

According to Apple's release notes, macOS Monterey 12.2.1 addresses a bug that was causing Bluetooth devices connected to Macs to drain an excessive amount of battery.

Following the release of the macOS Monterey 12.2 update in late January, MacRumors began seeing numerous complaints from users who were experiencing excessive battery drain during sleep mode, and the culprit appeared to be Bluetooth accessories that were frequently waking up the Macs they were connected to.

Some affected users saw their Mac's battery life drop from 100% to 0% while in sleep mode overnight after installing the macOS 12.2 update, with both Intel-based Macs and Apple silicon-based Macs affected. The problem stopped when Bluetooth was disabled or when Bluetooth accessories were disconnected from the Mac, which was not an ideal solution for users.

Apple addressed the problem in macOS Monterey 12.3 beta 2 yesterday, but now Mac owners will not need to wait for the macOS Monterey 12.3 launch to fix their Bluetooth battery drainage issues.

macOS Monterey 12.2.1 also fixes a WebKit bug that could allow maliciously crafted web content to lead to arbitrary code execution. Apple says that it is aware of a report that the issue may have been actively exploited, so Mac users should update to the new software as soon as possible.

Finally, Apple has also released new versions of Safari 15.3 for users on macOS Big Sur and Catalina, presumably addressing the same WebKit vulnerability fixed in macOS Monterey 12.2.1.

Does that mean there will be a Big Sur 11.6.4? Would be nice if MR acknowledge and report on both Monterey _and_ Big Sur.

Update: Just checked and no 11.6.4 update yet so either Big Sur is more stable and secure train or Apple hasn't bothered to push it out yet.

There was already an 11.6.4 in beta. Since the security update is in Webkit I'd expect to see a standalone Safari update for Big Sur and Catalina.

I know this is crAaAaAaAaaaaazy, but what if we didn't release a new OS with new features every single year and then spend the whole year fixing embarrassing bugs? What if we released a new OS every two years, but it was actually good? Would that be the worst thing in the world? Would all the users go away?

I think if that would happen the adoption rate for the new software would drop drastically. New features gets people excited thus they tend to upgrade right away.
