Mac os restart bluetooth service

Reset Mac OS X Bluetooth service?

Any way to do this either via a utility, command-line, or otherwise? I regularly have my headphones and moused paired which causes the Bluetooth service to crash nearly daily. Sometimes I can just repair the devices but other times the service breaks completely. When that happens I have to reboot; very annoying indeed. Is there a «Factory Reset» option for Apple Bluetooth keyboard, mouse, trackpad?

Either High Sierra or Mojave was the last OS to have the native options below. They are no longer viable on Catalina and up AFAIK. I (or someone) will edit in fixes for the latest macOS once we have tested / identified them. Seek support from Apple in the mean time.

I 2011 I there was not an easy fix (you had to download, install, and use developer tools), but soon thereafter on OS X, advanced features were provided from the Bluetooth icon in the menu bar. Hold shift and option (only) when clicking on the icon:

The debug menu has most of the action oriented items you’ll need:

I’ve never seen resetting the module work better than powering it off, but I’m sure theres cases where this speeds troubleshooting and might save a trip to the repair shop if software corruption / settings drift is the cause of issues.

Logging is useful, but the logs are very very large, so keep that in mind and set a reminder to turn it off tomorrow.

On older OS, you needed a developer tool to systematically remove pairing records and HID devices. Bluetooth Explorer ships with Xcode 3. (as of today, early June 2011 — this is something available at no cost if you agree to the terms of the free developer program. It might also be bundled with Xcode 4 — available with paid download or paid mac developer program — but I can’t vouch for that) You can also browse the developer documentation for free to learn more about bluetooth implementation.

The explorer has a detailed window with many settings to automate resetting devices for testing. Here is a portion of the window showing that not only are the local mac settings cleared, it will reach out to Apple Bluetooth devices and reset their internal state as well.

Since bluetooth has to start very soon in the boot process (and is part of the setup assistant since new macs that have no accounts have to know how to set up Bluetooth keyboards and mouse out of the box) it’s not just a simple user preference file but instead a system level preference and stored in several locations.

You will be able to make your mac factory fresh to test bluetooth with the Bluetooth Explorer.

Is there a way to turn bluetooth on & off without rebooting every time? Once or twice a week I’m unable to turn bluetooth off or on without rebooting. I’ve tried all the obvious steps (enabling or disabling via bluetooth icon in the menu bar, and going through the system settings to do it.) From all my research, rebooting is the only way, and that works but it sure is a hassle. I’m hoping there’s a way to turn it on or off through Terminal, or to reset the bluetooth service using sysctl or something. anything so I don’t have to reboot every time. Any advice? Thanks in advance. -Adam 2013 15″ mbpr, Catalina (10.15.15, which right now is the latest version)

Bluetooth not available after upgrade to Catalina I upgraded to Catalina on my Macbook Pro. Now I can’t turn on Bluetooth. My Mac is pretty old (10 years) so it’s way past its prime as far as application support, etc. I have a newer Mac so I mostly only use this one for video and music anymore. if I can’t connect airbuds, it’s essentially useless. Considering downgrading the OS if that’s the only option.

my bluetooth on macbook has disapperared from system preferences I am running OS Catalina version 10.15.5 on a MB pro (Mid 2012). I have been using a recently bought pair of AirPods without any trouble until yesterday (possibly coinciding with the update to the latest version of OS). Now my Bluetooth is not working, its has also gone from the Systems Preference. I have tried holding shift option and clicking on the Bluetooth symbol, I get ‘Open PacketLogger’ but nothing happens when I click on it.

Use «Reset the Bluetooth module» to Fix Constant Bluetooth Disconnections

A. When to Reset the Bluetooth Module:

If you are using a Bluetooth device and it keeps disconnecting, then what you need to do is reset the Bluetooth Module.

To All Readers:

Recommend this Comes Back:

Bluetooth seems to be a big issue for many out there who are using macOS Monterey. And with Resetting the Bluetooth Module no longer being an option in the method provided above in my original post, it would be best to recommend that it comes back, in my opinion.

Do your Part: Inform Apple of your feedback of this issue. Include that you want Resetting the Bluetooth Module in this manor to come back. Apple wont get back to you directly, but the more feedback they receive from its users, the more likely they will know what suits their customer prefer, and what to include in macOS versions to come.

1. Go Here:Feedback — macOS — Apple
2. Select: «Performance» for the «Feedback Type«
3. Select: «Software/Firmware Update» for the «Feedback Area«
4. Comment: That you want Resetting the Bluetooth Module option to come back.
5. Proceed from there as necessary

Tips on Resetting the Bluetooth Module:

Resetting the Bluetooth Module in that method is simply just no longer an option. It is just not part of macOS Monterey. For reference, I wrote this user tip back in April 2021, prior to the release of macOS Monterey: Use «Reset the Bluetooth module» to Fix Constant Bluetooth Disconnections — User Tip. So, try the following.

Sadly, none of these instructions worked for me. I’ve deleted the indicated file, emptied the trash and restarted three times. Bluetooth speakers still not working now that I’ve upgraded to Monterey (MacBook Pro 2016).

Neither of these is working for me.
• There is no plist file:
com.apple.AssetCache.plist
com.apple.BezelServices.plist
com.apple.biometrickitd.plist
com.apple.ByteRangeLocking.plist
com.apple.commerce.plist • When I enter the command in terminal and my password, return gets me back to
Mac:~ WD$ sudo pkill bluetoothd
Password: [enter and hit return]
Mac:~ WD$ Other people are complaining of the exact same thing. Using OS 12.4 on a MBP

So I put com.apple.Bluetooth.plist in trash and emptied it and it’s completely gone to the point where my laptop won’t connect to anything. How do I fix this.

I ran the sudo command and it didn’t seem to improve anything, so I went to step 2. I found there was no com.apple.Bluetooth.plist file in the specified location. I assume the pkill command removed it, but a couple of restarts and one complete shutdown and restart did not restore it. Note that this is an M1Max, and my 2019 Intel MacBook, running Monterey does have this file. Is this different for the M1Max, or is this yet another bug in the Bluetooth farce? When I look at my Bluetooth Preferences it says “Now discoverable as: [my computer name]”, but if I click on the Bluetooth icon in the menu bar while holding down shift-option, it shows “Discoverable: off”. Yikes! However, after rebooting my Magic Trackpad and my MX Master 3 mouse are still working fine, but I can’t get it to find new Bluetooth devices.

I have exactly the same issue as John Howard, except that my problematic hardware is a 2018 Mac Mini (Intel). This is driving me crazy! I have tried all the recommended “fixes” from multiple sites and none of them are working. All I want to do is use Universal Control between my 2 Macs, but issue this is causing it to not work.
