macOS Monterey 12.3.1

Around the same time as iOS and iPadOS 15.4.1, Apple just released a new public version of macOS Monterey, numbered 12.3.1 for the occasion. For the moment, no additional functionality has been detected except the compatibility with Business Essentials but it is possible that early testers will report their findings in the coming days.

Several technical problems have however been resolved, suggesting that the wanderings of the last days are finally behind us:

  • some 2021 MacBook Pros couldn’t update to macOS 12.3 or roll it back
  • playing audio with Beats headphones could disable Bluetooth-paired devices to the Mac, such as video game controllers
  • Thunderbolt or USB-C monitors not turning on when connected to a 2018 Mac mini as a second display

Note that two security failures scale (zero day) have also been met. Each was reported by an anonymous researcher. The precise list of affected machines has not been communicated, but we know that one of the breaches concerned Intel graphics card drivers. It is therefore very likely that Macs with an Apple silicon chip, i.e. the most recent, are not affected.

The path to upgrade your Mac to macOS Monterey 12.3.1 is as follows: System Preferences > Software Update > Upgrade now. And to find out if your equipment is eligible, just consult this list.

Apple TV and HomePod

The tvOS 15.4.1 release notes, posted overnight again for Apple TV 4K and classic editions, don’t mention any major changes either. Same thing for HomePod and HomePod mini, whose operating system goes into version 15.4.1 also a few days after the speakers hit the Swiss market.
