Because the launch of macOS Monterey 12.2 final month, a number of customers have been complaining about an in a single day battery drain on MacBooks that was associated to Bluetooth. Now with macOS 12.3 beta 2, Apple appears to have fastened this bug.

For some unknown purpose, the Bluetooth on the MacBooks wasn’t maintain disabled when the machine was put to sleep. Consequently, the machine saved waking up by itself even when the Mac wasn’t in use, which drained the battery extra rapidly.

Fortunately, the newest beta model of macOS Monterey 12.3 – which was launched on Tuesday for builders – now not has this problem. Checks carried out by Mr. Macintosh present that MacBooks operating macOS 12.3 beta 2 are now not all of a sudden woke up from sleep due to Bluetooth connectivity.

As famous by my 9to5Mac colleague Ben Lovejoy, customers operating macOS 12.2 have two alternate options to keep away from battery drain. One in every of then is popping Bluetooth off earlier than placing your Mac to sleep – which isn’t precisely handy when you’ve got a Bluetooth mouse and keyboard. The opposite choice is to put in a instrument that mechanically turns Bluetooth off proper after you shut the Mac’s lid.

So whereas Apple hasn’t but issued a repair, there may be a minimum of a clunky workaround: Change off Bluetooth earlier than you set the machine to sleep, and re-enable it while you wake the machine. In fact, if you happen to use the machine in clamshell mode with Magic Keyboard/Trackpad/Mouse, you’ll must open it first to re-enable Bluetooth utilizing the built-in trackpad.

macOS Monterey 12.3 beta is now obtainable to builders and public beta customers. The official launch is predicted this spring.
