Apple releases macOS 12.3.1 update that fixes bugs connecting external monitors and game controllers
The recently released macOS Monterey 12.3 introduces exciting new features, including universal controls, Unicode 14 emojis, and more that were already known to be coming, and this version may also be the last major update to macOS Monterey, as Apple may Attention and major resources have been diverted to the upcoming macOS 13 beta.
After the release of macOS 12.3, some users began to report that the external monitor they were using had problems. Some people received a no-signal prompt when trying to connect the monitor to the Mac via USB-C. Other users also reported that the external monitor was connected via HDMI. Displays have also failed, troubling many people who rely on multiple monitors for their work.

In addition to the display issues, macOS 12.3 also caused problems with Bluetooth game controllers. Some users of PlayStation, Xbox and third-party controllers reported on the forum, but the situation they encountered was different. Some controllers fail in random games, while other gamers with the same controller model don’t experience any issues at all, given the number of variables that cause problems, it’s difficult to determine the conditions that cause these problems, and macOS 12.3 is one of the few common conditions.
In addition to fixing the external monitor issues and game controller issues mentioned above, macOS 12.3.1 also fixes two security vulnerabilities. How to install the update?
