Bluetooth Disconnecting After Waking From Sleep

Hello juleek,

Does that persist after updating your Mac to the latest macOS 12.3.1 using the steps below?

1. From the Apple menu  in the corner of your screen, choose System Preferences.

2. In the System Preferences window, click Software Update.

If your System Preferences doesn't include Software Update, learn how to upgrade to macOS Monterey or upgrade to an older macOS, and use the Updates tab of the App Store app to get app updates.

3. Click Update Now or Upgrade Now:

• Update Now installs the latest updates for the currently installed version, such as an update from macOS Big Sur 11.5 to macOS Big Sur 11.6. 

• Upgrade Now installs a major new version with a new name, such as macOS Monterey. Software Update shows only upgrades that are compatible with your Mac.

When Software Update says that your Mac is up to date, then macOS and all of the apps it installs are up to date, including Safari, Messages, Mail, Music, Photos, FaceTime, and Calendar.

How about after booting your Mac into safe mode using the steps from this article? How to use safe mode on your Mac

It can take a few extra minutes to boot into safe mode. Your screen may flash or flicker while in safe mode. Those behaviors are expected. Testing in safe mode runs a check on your disk, removes some cached files, and can help isolate conflicts with startup items.

Let us know your results, and we'll keep moving forward from there.

Hi juleek,

We would recommend that you contact Apple Support, so they can look into this further. As a Bluetooth device, by design, such as your mouse or keyboard, should be able to wake your iMac.

Apple Support

Tell them exactly what's happening, which Bluetooth devices you're using, and the troubleshooting you've done.

In the meantime, to wake your iMac try lightly pressing the power button to wake your iMac.

Thank you!

I have the exact same problem. Mac Studio. All updates. When system goes into a deeper sleep, keyboard, trackpad and mouse all are dead. I have to quick-press the power button to turn off the screen, then again to turn it back on to get them recognized again. Battery on all devices >75%.

I'm now using macOS Monterey 12.3.1 (21E258), but sometimes I'm having issues with Bluetooth. Both my mouse and keyboard are disconnected, and I have to turn Bluetooth on/off to make it work again.
