Is your MacBook slowly dying in its sleep? It could be because of a frustrating Bluetooth bug in macOS 12.2 that’s causing severe battery drain for some users. But there’s no need to wait for Apple to fix it.

With the help of a simple (and incredibly affordable) app, you can automatically disable your MacBook’s Bluetooth connection when you close its lid — then enable it again when it’s reopened. We’ll show you how.

Fix macOS 12.2’s Bluetooth bug

The Bluetooth bug, which surfaced soon after Apple rolled out macOS 12.2 in late January, affects MacBook Air and MacBook Pro units running Intel and M1 chips. It causes machines to continually wake up when they should be asleep.

If you don’t leave your MacBook plugged in overnight, there’s a good chance you’ll wake up to a completely dead battery. But you can prevent that — before Apple properly fixes the problem — with a simple app made by Jordi Bruin.

FluTooth automatically disables your MacBook’s Bluetooth connection when you close its lid, then enables it again when you open it. You could do this manually, of course, but with FluTooth installed, you never have to worry about it.

Get FluTooth for macOS

One of the great things about FluTooth is that it’s incredibly affordable. Its developer invites users to make a donation when they download the app — and we recommend doing so to say thanks, if you can — but you don’t have to.

If you haven’t yet installed macOS 12.2 on your MacBook, the simplest way to avoid the Bluetooth bug is to stick with macOS 12.1 for now. It’s not clear how long it’s going to take Apple to fix the issue, but macOS 12.3 is in testing.
