Apple has also released an update to solve the battery drain issues some Mac users experienced since upgrading to macOS 12.2.

The release notes for the new version, 12.2.1, say it contains fixes for "an issue for Intel-based Mac computers that may cause the battery to drain during sleep when connected to Bluetooth peripherals", reports The Verge.


Before this update, some users reported their MacBooks' batteries would drain while the computer was asleep, sometimes even reaching 0 per cent charge overnight.

While there was evidence that Bluetooth was the culprit, some users reported that turning off Bluetooth before closing their computers didn't help, making it slightly unclear what the issue was.
