Apple has released macOS Monterey 12.3.1, which includes Bluetooth and display improvements

Apple has published macOS Monterey 12.3.1, a small upgrade to the operating system that was first released in October. Two weeks after the release of macOS Monterey 12.3, which included Universal Control, comes macOS Monterey 12.3.1.

According to Apple Insider, macOS 12.3.1 includes improvements for USB-C or Thunderbolt displays not coming on when attached to a 2018 Mac mini as a second display. Apple also solved a problem that caused Bluetooth devices, such as game controllers, to detach from a Mac when Beats headphones were plugged in. The macOS Monterey 12.3.1 update can be obtained from the Software Update section of System Preferences on supported Macs. The Software Update menu in the System Preferences app can be used to update a Mac.

All eligible Macs can download the macOS Monterey 12.3.1 update from the Software Update section of System Preferences.

According to Apple’s release notes, macOS Monterey 12.3.1 includes a patch that prevents Bluetooth controllers, such as game controllers, from disconnecting from the Mac when using Beats headphones. It also fixes a fault that prevented USB-C or Thunderbolt external displays from turning on when used as a secondary display with the 2018 Mac mini.

An AppleAVD problem that might let an application execute arbitrary code with kernel privileges and an Intel Graphics Driver issue that could allow an application to read kernel memory are also addressed in macOS Monterey 12.3.1.

According to Apple, these weaknesses may have been aggressively exploited, thus all customers should upgrade as soon as possible.

iOS 15.4.1, iPadOS 15.4.1, tvOS 15.4.1, watchOS 8.5.1, and new 15.4.1 firmware for the HomePod were all included in today’s macOS Monterey update.

Several reports have recently surfaced on the Apple Developer Forums and Reddit, with users describing varying degrees of difficulty.

External monitors are having issues with macOS 12.3. When connecting their monitors to their Macs through USB-C, some individuals are experiencing No Signal alerts on their monitors.
