Bluetooth crashes in MacOS Sonoma (M1 MacBook Pro)

I just upgraded to MacOS Sonoma. Now my bluetooth crashes every 15-45 minutes. Bluetooth turns off entirely (not just devices losing connection).

I already tried all the "bluetooth issues" troubleshooting I found online:

unpaired and repaired everything
deleted `/Library/Preferences/com.apple.bluetooth.plist`
reset bluetooth module with `sudo pkill bluetoothd`
restart computer
turn off wifi

Nothing has worked.

Now I notice a few Crash Reports in the Console app.

Note this does NOT represent all the times bluetooth has turned off (like I said, it probably every 15-45min), but I wonder if maybe it can provide some clues.

Any advice on how to proceed?

Attached is the full copy from the most recent crash report:

Adding my journey to the log here:

Short Story: Wipe the entire drive and reinstall/downgrade to Mac OS 13 Ventura.

Long Story: Like many others here, my Bluetooth has been cutting in and out since upgrading to Sonoma. For me, it was happening several times a day. My Mac is an M1 Macbook Pro, and the connected Bluetooth devices are a Magic Trackpad, AirPods (seldom connected), and Keychron Q1 Pro. Here's a list of things I tried that haven't worked:

spoke with Apple support several times, including capturing and sending extensive logs to them - no dice
tried the Onyx approach listed in this thread - no dice
ran diagnostics - no issues detected
reinstall Mac OS 14 Sonoma without wiping entire drive - no dice
reinstall Mac OS 14 Sonoma with wiping entire drive - no dice
reinstall/downgrade to Mac OS 13 Ventura with wiping entire drive - success!

Bluetooth has been stable now for several days. At first it wanted to detect my keyboard a few times (more than was needed), but that's since disappeared. I'll be waiting at least several months before testing out Sonoma again on a different drive. Rough stuff.

Note - after running diagnostics I tried downgrading to Mac OS 13 Ventura, but wasn't possible without wiping the drive, as the installer refused to do so. That's when I worked through each of the above 'reinstall' steps.

Edit - I have also tried upgrading to the latest 14.x.x versions - no dice

I am also going to downgrade back to Ventura tomorrow or over the weekend.

Can confirm this. I’ve switched to using it via USB instead of Bluetooth, but I have no crashes when using an Apple Keyboard. I prefer the Keychron keyboard though, so I’ll just use it via USB now.

Uh oh! I am sensing a trend. I am ALSO using a Keychron keyboard (K1, lastest rev). Is this a Keychron issue, and not an Apple issue???

I have no unused devices lying around, unfortunately. Also, the other suggestions here like restarting don't work and I don't have the time for a clean reset and reinstall of the OS, it's a work computer.

the problem usually only occurs after I unplug at least one Thunderbolt device, which often crashes the Mac or puts it into a sort of a half-crashed limbo where some stuff still works, and other things do not.

I wish it crashed for real so I could send a report to Apple…

Bluetooth Handoff is broken with Mac OS 14.1 and iOS 17.1. Cannot connect my devices. Handoff doesn't work. When trying to connect two Apple devices, I get a message that either pairing fails or "device not supported."

I experience the same problem intermittently. It occurs when my external keyboard, mouse, and trackpad disconnects unexpectedly, requiring me to power off these devices and then power them on again to re-establish the connection. This issue can be quite frustrating, and I've been seeking a reliable solution to address this inconvenience. If you've encountered a similar problem or have any suggestions for resolving it, I'd greatly appreciate your insights. Happened after upgrade to MacOS Sonoma.

Keep us informed. I experience this only rarely on my M1 Studio Max. Either keyboard, mouse, or both just stop working for a minute or so. Turning them off/on resolves the issue. But as I said my experience is very rare but does happen.

Same issue here. Did anyone get an ETA from Apple as to when this will be resolved? Not being able to use keyboard/mouse/trackpad regularly seems pretty fundamental and you would expect this to be given priority.

The problem still exists with macOS 14.1.1.

I unpaired all Bluetooth devices and ran Onyx maintenance, as some people described here, but it did not fix the problem for me. After a day the disconnects returned.

The culprit could be the 3rd party "maintenance" app(s) you use, why not allow MacOS itself to do the maintenance? A few restarts of your Mac would take care of itself, of course, if you don't have any 3rd party modifier apps, antivirus and so on.

Of course I rebooted the MacBook many times before I tried the maintenance tool. A reboot only helps temporarily but doesn't fix the problem at all.

Come to think of it, my MacStudio also plays music to HomePods with no issue, no disconnects, but Apple magic keyboard, mouse and my Beats Studio 3 headphones have the disconnect issue.

Most probably, because the Apple Magic devices were created in the Intel days, and the emulation software might not be good yet with M chips. When you go over to Sonoma in that Intel MBP, it'd be interesting to know how it goes.

I just had a quick look through all the comments and no one really says on what Macs they are experiencing this, but to me it looks it is only affecting Macs with Apple Silicon. I have the issue on a MacStudio M1 Max.

I have a 2021 MacBook Pro 16" with an M1 Max.

By the way: The problem already occurred two times today :(

Bug fixes do not seem to be at the top of Apple's priority list. One update follows the next, but above all, users will once again be served up lots of bells and whistles. The next really big and amazing innovations are already in the works. With new bugs.

Nothing serious here indicates a hardware issue ...
