Bluetooth pervents iMac 27" (2019) and MacBook Pro 13 (Intel 2019) from sleeping

Thank you for being the one to sit through this pain for all of us. I was like "what is this support article talking about? there's no 'advanced' button on that screen"... maybe it will show up again after a future update, and that will make this thread all the more confusing to future readers ha

Hello, der001mac. Thank you for using the Apple Support Communities, welcome! We understand that you have been noticing an issue when using your iMac where the Mac is waking from sleep unexpectedly. We know that being able to manage when your Mac is powered on must be important to you, and we can certainly help you with this situation. 

We understand that you have already isolated the issue to one of the Bluetooth connections that your Mac has. We have several more suggestions that we think will help you continue from here. 

For the next step, we would suggest reading over the following Apple Support article. This article contains information on what to do if you are noticing that your Mac either goes to sleep, or exits sleep mode unexpectedly: 

If your Mac sleeps or wakes unexpectedly - Apple Support

If this seems to be caused by a Bluetooth connection, you can find steps to mange the system’s Bluetooth settings in the article above. According to the article: 

"Bluetooth devices can wake your Mac. If you don’t want a Bluetooth keyboard or mouse to be able to wake the Mac, you can change your system’s Bluetooth settings. 

Choose Apple menu > System Preferences, then click Bluetooth. Click Advanced, then deselect “Allow Bluetooth devices to wake this computer.”.” 

If you continue to notice the same issue after this, we can help you more. To continue, it would be helpful to know if this same problem occurs after your Mac has been started in safe mode. Safe mode is a way we can isolate out the software that may be causing this issue. You can see how to use safe mode in this last article: 

Start up your Mac in safe mode - Apple Support

If you still notice the same issue while in safe mode, please reply back here and we will be able to help you more with this. 

We hope that this information helps you. 

Have a great day! 

Hello, der001mac . Thank you for replying back with more information about your iMac. We understand that you are noticing the same issue after your Mac has been started in safe mode. 

We’d like to isolate this issue a bit more to continue. To confirm, it sounds like this issue does not occur when Bluetooth is disabled in your Mac’s preferences. Is that correct? 

If you remove all Bluetooth accessories except for the Magic Mouse and Keyboard, do you notice the same issue? 

Finally, we would like to find out if the same situation occurs when you are signed in to a second Administrator user account. If you only have one Administrator account created at this time, the Apple Support article below can help explain how to create a new account for testing with:

Set up users, guests, and groups on Mac - Apple Support

Please let us know what you find out. 

Thank you for replying back with the results, der001mac. 

We understand that you were able to duplicate the issue from a second user account, and with only the Magic Mouse and Keyboard connected. 

To help you continue from here, we would suggest that you contact Apple Support directly for more help. Depending on your location, you may be able to contact Apple Support using the following link:

We appreciate your patience so far in isolating the issue. Please let us know if we can help you move forward from here. 

Have a great day!

This was a great link right up to the point that it moved off the thread.

I have identical issues and took identical steps. I am sure, gauging from this and other threads here and on MacRumors and Reddit, that this is not a unique problem.

I would be curious to know if you did, indeed, contact Support, and what was the outcome of that stellar experience.

Thanks

Thanks for the prompt response.

I, too, look forward to another ‘timely’ Apple response/non-response/denial/down-playing to yet another unrecognized yet seemingly widespread issue that may suddenly find itself resolved and given a footnote in the details of some future update.

Same Problem here on a Mac Mini 2018 with clean install and no other software installed. This is a problem within the 12.2 OS and is also causing many laptops to lose battery charge during the night if they have bluetooth mouse or other things

connected.

The workaround is to turn off bluetooth or turn off your mouse and Keyboard and use wired devices. No need to waste a lot of time troubleshooting.

I find it interesting that my iMac late 2015 i7 with 12.2 is sleeping normally. The problem must affect only certain configurations of bluetooth. The reports I am hearing are mainly late model Macs and Macbooks.

Same issue, MBP 16' 2019. Looks like they have found the issue and will be fixed in the next OS release.

In the meantime, the only thing we can do is disconnect all Bluetooth devices or turn Bluetooth off when we intend to send the computer to sleep.

Are you by any chance using a Logitech MX3 Master mouse? I just bought one and am seeing a new problem of waking from sleep a couple of times an hour. If I turn it off and use only my Apple mouse sleep works fine with 12.21

Hi John,

I'm using the MX Keys for Mac Keyboard and the MX Master 2S mouse. I did add the MX Keys for Mac Keyboard just prior to upgrading to Monterey though. But I wasn't having any issues with either of those on Big Sur. I'll disable the keyboard and see what happens.

Yes I am. However, the problem persists when switching back to the Apple Magic Mouse. I bought the Logitech mouse before updating the OS and there were no issues.

The problem goes away when I boot my dual-booted Mac to Windows 10. Sleeps like a baby 😑
