Apple Releases macOS Monterey 12.3.1 With Bluetooth and Display Fixes

Apple today released macOS Monterey 12.3.1, a minor update to the ‌macOS Monterey‌ operating system that launched in October. ‌macOS Monterey‌ 12.3.1 comes two weeks after the launch of ‌macOS Monterey‌ 12.3, an update that brought Universal Control.

The ‌‌‌‌‌‌macOS Monterey‌‌‌ 12.3‌‌.1 update can be downloaded on all eligible Macs using the Software Update section of System Preferences.

According to Apple's release notes, ‌macOS Monterey‌ 12.3.1 introduces a fix that could cause Bluetooth controllers like game controllers to disconnect from the Mac after playing audio through some Beats headphones. It also addresses a bug that could cause USB-C or Thunderbolt external displays to not turn on when connected to the 2018 Mac mini as a secondary display.

This update fixes the following issues:
- USB-C or Thunderbolt external display does not turn on when connected to Mac mini (2018) as a second display
- Bluetooth devices, such as game controllers, may disconnect from your Mac after playing audio through some Beats headphones

‌macOS Monterey‌ 12.3.1 also addresses two vulnerabilities, including an AppleAVD issue that could allow an application to execute arbitrary code with kernel privileges and an Intel Graphics Driver issue that could allow an application to read kernel memory.

Apple says these exploits may have been actively exploited, so it is a good idea for all users to update as soon as possible.

Today's ‌macOS Monterey‌ update was also accompanied by iOS 15.4.1, iPadOS 15.4.1, tvOS 15.4.1, watchOS 8.5.1, and new 15.4.1 software for the HomePod.

Bit alarming that the external display bug is referenced purely as a Mac mini 2018 issue, rather than on iMacs and MBPs too - either they haven't fixed the issue for all, or they don't know fully understand what the issue was.

Still, nearly download on my iMac 2017 with dual, borked external displays so will soon find out.

Edit: Yes, it fixed it.

At this point, can anyone tell me if there are still any memory leaks in Monterey? Or have been fixed all of them?

Any other major bug on Monterey? Or is this a safe release to jump from Big Sur?
An operating system contains millions of lines of code. It will never be perfect and there will always be some memory leak somewhere. But the major ones seem to be under control.
I work in software Quality Assurance and I can guarantee you that perfect software does not exist!

I hope this also fixes the issue with Quick Previews. After a while, hitting the space bar only shows a tiny thumbnail instead of previewing the file as it should. The only way to fix this is to restart Finder which is frustrating since it will usually close all Finder windows.

Before any problem can be fixed, the company first has to admit that there is a problem, not ignore it or claim ”it’s a feature, not a bug”.
