Bluetooth crashes in MacOS Sonoma (M1 MacBook Pro)

I resolved by unpairing the keyboard and mouse, running Onyx maintenance and rebooting and then repairing the keyboard and mouse. Of course, if you don’t have a laptop, you will have to find a wired keyboard and mouse to perform this.

I’m experiencing the same issue and it is so bad, I’ve been considering downgrading or getting a USB-keyboard. I’ve tried basically everything to fix it, but I’ve not had any success yet. I really hope Apple takes this seriously and fixes it in my lifetime.

I experienced this symptom repeatedly since upgrading. Although I can't confirm exactly it was the bluetooth daemon crashing, I was losing connection to my Apple Magic Trackpad 2, and HHKB keyboard simultaneously.

A restart subsequent to upgrade has apparently resolved the issue.

Apparently, the guys in Cupertino, who usually have such a big mouth when it comes to praising the superiority of their oh-so-great amazing products, didn't manage to fix the problem with the 14.1 update either.

2900 Euros for a computer, but a support and a culture to take care of bugs, like a cheap backyard workshop from the Far East. I can't even describe how Apple is getting on my nerves by now.

I chatted with Apple and they are aware of the issue. However, it would give the issue a higher priority if more people got in touch and notified them they have the same problem.

I also noticed that with macOS 14.0 devices would auto-reconnect after BT crashed, but with macOS 14.1 devices do no longer automatically re-connect and I often have to power-cycle my keyboard and mouse to get them to connect again.

Did you perform a factory reset of the computer (i.e. have to start fresh and reinstall everything) or a factory reset of the bluetooth settings?

Reported the bug, still getting it on 14.1.1 on my MacBook Air M2, 2022 - usually multiple times within a 1 hour period. Can we please get this patched already? *sigh*

Same with 14.3.1. Not too frequent but pretty annoying. Any chance to fix it?

Has anyone read my post? I solved it in 14.0. Here are the steps: ( you will need a wired keyboard or if you’re using a laptop, you can use the laptop keyboard)

1. unpair the Bluetooth keyboard and mouse. Make sure they’re gone from Bluetooth.
2. download and install Onyx
3. select Maintenance tab in Onyx and disable under Rebuild: Launch Services Database. Under Misc Options, disable Font Cache
4. click Run Tasks, this will run and ask you to reboot.
5. after reboot, re-pair your Bluetooth keyboard and mouse

this worked for me, MBP M1 14”

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

As explained several times in this thread, the solution is quite symple:

1. Install Onyx.
2. Remove ALL bluetooth devices in settings.
3. Execute maintenance in Onyx.
4. Let it reboot.
5. Pair all your devices again.

And done. All problems solved. It seems related to file permissions and caches, which Onyx solves completely.

Hope it helps.

I had the exact same issue after Sonoma upgrade. Waited until the latest 14.3 Sonoma even and still bluetoothd crashes repeatedly and airdrop is unresponsive.

From the logs it looked like a permission issue that I never managed to get resolved or find the root cause of.

After 3 months now of trying everything I now completely wiped the drive and went back to Ventura.

Everything works perfectly now including bluetooth, all my bluetooth devices ( AirPods, keyboard and mouse ) as well as airdrop

Fresh install of 14.3.1 on iMac with Intel processor (i.e. the issue is not restricted to M1 as someone suggested), and the issue persist. Well, it does not take 15 minutes to crash, bluetoothd crashes immediately. The solution with OnyX maintenance did not help neither.

I spoke at length with Apple Support, and they said it’s a known issue with certain models (I’m on a 2021 MBP 16 M1 Max w/ 64 GB ram). When I asked about a fix or a repair under AppleCare, they told me:

1.) it’s not a hardware issue, so it’s not covered under AppleCare

2.) the devs are aware of the issue, and they are no longer needing logs from users

3.) there is no timeline for a fix

4.) I should be “on the lookout” for a future update that might include a fix.

This is nuts.

When I really pressed for options, I was basically told that I could buy an M2 or M3 at full price. 🤬

So it appeared that the problem only occurred when I used the Keychron K8 Pro keyboard. Once I switched to Magic Keyboard, everything went back to normal. Zero issues so far while the bluetooth would crash every hour or so with Keyrchon. Love the Keychon keyboard, not sure why it is causing issues with Mac, it works perfectly fine on Windows.
