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:


MacBook Pro 14″, macOS 14.0

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

A warranty IS a "legal" guarantee. That's its literal definition.

Warranty is not exactly a legal guarantee, it is just an agreement between two parties. A legal guarantee is governed by the given country's law. In my country, for example, there is a 2 year guarantee on any new device that's governed by the country's law. A defective device or part of it has to be replaced or whole device replaced or refunded within the 2 year period. That is, it could be on the last day of that guarantee. It is the seller, who has to do that, and no seller will sell anything from any manufacturer, if that manufacturer will not abide by the country's laws. All those shops, internet or stationary, don't buy the devices from the manufacturer, but the sells the devices sent to them by the manufacturer, or by its agent, and what's not sold in a given time frame are sent back. The seller pays for only the sold items, and after a certain agreed amount of days, most times, within 4 weeks. Anyway, the consumer's rights are much higher than the manufacturer's rights, or the seller's rights in my country.

In any event, me and a coworker both have Apple Silicon Macs and both of our bluetooth devices fail regularly since Sonoma. It happens about 3-4x per day for about 10 seconds, then works and connects.

In the matter of Bluetooth cutting itself off, it is a normal thing is many devices, Android, Linux, Windows or even in Mac. There are lot of reasons why that happens, and sometimes there is no why, it just happens. The best way is to disable and re-enable Bluetooth. Most times, the Bluetooth module in the device cannot connect with a few external Bluetooth devices. This happens when those external devices are fighting each other to get the connection, and by doing so, break each other's connection, or everyone's.


If that happens, it means the Bluetooth module is malfunctioning, as it cannot hold the connection(s). The Bluetooth module also takes lot of energy. If a connection breakage happens with many external devices connected, better to disconnect few and leave only the most important ones connected. Or, if you find that a headache, show your Mac to a technical person, so that person can physically check it. Otherwise, revert to an earlier OS, if that, as you say, worked well for you. If you continue to state that the fault is in the new OS, then send a feedback.


(Here's an article in LinkedIn why your Bluetooth device fails sometimes.)

In view of the reports, it should be obvious that the fault lies in the operating system. If an error does not appear before an update and suddenly occurs after an update for many users with different devices and different configurations, it must be assumed that it has something to do with the update. The problem also affects users who do not have several competing devices connected, but only one.

I had a flawless experience with my MacBook Pro M1 and Apple mouse, keyboard, and trackpad until updating to Sonoma. Since then, two or three times a day Bluetooth just stops working. As soon as I use the MacBook's trackpad to turn off and on Bluetooth, everything comes back and works for a while. Yes, I've reset the Bluetooth module, restarted multiple times, etc. I'm on 14.1.1. I'm confident Apple will figure it out and include a fix in a subsequent release.

Well, I’ve been spending some time looking at this from multiple angles, and it seems to be an M1 problem. M2 and M3, as well as Intel seem to be unaffected. Same as with the USB DAC issue, where audio stutters/crackles when you connect an amplifier via USB. It seems there is a problem in the M1 Chip that causes at least two very hard to solve issues in Bluetooth and USB. I guess the resale value of tose Macs just dropped even more…

I'm getting the same problem with my PB since upgrading to Sonoma, and now on 14.2 - bluetooth drops all devices randomly throughout the day: mouse, trackpad, keyboard (all Apple devices). I have to keep the Settings>Bluetooth window open to cycle BT off then on again to reconnect to my devices using the laptop's pad. Really annoying when on a vid-call and you want to unmute, or typing away only to find you're last x characters were never seen. I have to post a support request through my IT instead of directly with Apple.

From the title of this thread, most of the messages in it, your post and my own experience I believe this issue is relevant for M1 based devices (both laptops and desktops) after their upgrade to Sonoma. Entire line of M1 CPUs is affected (Pro/Max/Ultra). Haven’t seen any references to M2/M3 devices. So let’s stick to the theory, that issue affects Macs with M1 processors. I believe chipset (or at least its part responsible for BT) is the same for all of those as well.

these commands may work if your not in clamshell mode. if you are in clamshell with a wireless keyboard and mouse, your dead in the water. continuously hitting the return key or clicking the mouse will force reconnection or plugging in the wireless devices will reengage. the bluetooth is going to sleep just like apple tech support is asleep. hey apple when are you going to fix this problem? are you out there? are you paying attention to these boards or are we wasting out time posting?
