After launching the first macOS Monterey 12.3 beta to developers and public testers with the exciting Universal Control feature enabled at the end of January, the second beta has arrived today with several bug fixes including one for a Bluetooth-related battery drain fix.

Update 2/9: The second macOS 12.3 beta is now available for public testers too.

The second macOS Monterey 12.3 beta is now available via OTA for developers and public testers already enrolled in the beta as well as being available to download from Apple’s Developer website or public beta site. macOS 12.3 beta 2 arrives with build number 21E5206e.
