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 can't beleive this is still hapening.

This is the 4th time that happened to me today.

Bluetooth just crash from nothing every certain amount of time.

It's so ANNOYING, my mac is brand new.

Can't beleive.

I "upgraded" from Ventura to Sonoma two weeks ago, and have regretted it ever since. After installing Sonoma, my Bluetooth keyboard and trackpad have been randomly dropping offline many times a day. It's been infuriating. I'm on a Mac Studio M1 Ultra -- way too pricy a computer for this kind of nonsense.

This actually got worse for me with 14.4.1. I keep expecting some new upgrade will fix it, that Apple will have put someone on it who solves the problem. It is hard to be patient when the issue is common and the problem is clearly software; my Bluetooth was flawless on my M1 MBP before Sonoma. I keep wondering if there is some factor that unifies those experiencing the problem. Is it exclusive to the BCM_4387 chipset? From System Report:

Bluetooth Controller:

In one of the recent messages in this thread post author was recommended by Apple support to buy M2/M3 Mac to “solve” BT issue. If M2 is also affected, than I don’t know what else can force devs to fix this. Just insane. :(

Are you sure? I had similar feeling that Onyx helped me couple of Sonoma versions ago, but at the end it didn’t. Temporary relief was brought by MacOS reboot, which follows Onyx repair procedure, but after some time of inactivity my MacBook went to sleep and when I woke it up, faced all the same problems with BT.

MacBook Air 15", Apple M2, Sonoma 14.3.1. Have had Macbooks since the Apple Powerbook G4 Titanium in 2001.

Since I migrated to Sonoma the Macbook stops the bluetooth connection with the Apple keyboard and mouse. It happens totally randomly: sometimes it works for hours, sometimes it stops 5 x in 30 minutes. Only thing that helps is switch Bluetooth off and on and wait 5-10 seconds until the Bluetooth connection is restored.

Apple, This Is Ridiculous!!! Fix This!!!

M2, mmm interesting. Thus far only saw M1 users complain. Good to see it just isn't M1.

I have also noticed that this bluetooth bug has crept into Ventura, latest 2 versions disconnects bluetooth, but not as bad as Sonoma. At least when you click a key on keyboard or press mouse button, it re-connects immediately.

I am using all apple hardware. bluetooth randomly drops external keyboard and mouse. Looks more like it goes to sleep. If you keep clicking mouse, plug in via wire, turn on off. the reconnect can be any of the 3. Bottom line there is a problem with the apple software Bluetooth connectivity.

getting annoyed with the bluetooth dropping, I started to search if anyone else has this: found this tread!

It is unbelievable!

I recently upgraded to a Mac Studio M2 with Sonoma on board.

initially thrilled by the upgrade (still am though), getting used to the speed of things goes really fast. Now starting up my old iMac 2012 seems like … much slower!

but: (!) BT keeps dropping. I run 14.4.1 (23E224)

this seems to be a major thing?

Every now and then my trackpad looses connection. The keyboard works mostly fine both are Apple 🍏

my software is up-to-date, so I guess it must be a problem with Sonoma.

Let’s hope it will be solved in a coming update?

It is annoying, but the disconnection is not frequent.

i have all apple equipment, bluetooth goes to sleep without notice, need to force keyboard and mouse to reconnect. based on all the posts, the is an operating system problem. I have M1 processor , people with newer M2 are also having the problem.

Apple are you reading these boards?

In macOS Sonoma 14.4.1 the problem has gotten worse: Bluetooth disconnects the Apple mouse and Apple keyboard, does not auto-reconnect anymore, but in stead you have to switch Bluetooth off/on and then it reconnects.

I use a MacBook Air 15" M2.

Apple fix this!

Well, all you need is the first and the last step. MacOS will take care of the rest. 👌

And I spoke to soon, just had bluetooth hang for around 30 seconds then it auto re-connected

Nov 14, 2023 12:53 AM in response to Caffeine81

I agree, this is not a hardware or 3rd party issue, this a Sonoma issue. This issue wasn't there with Big Sur or Ventura, only started with Sonoma.
