Chances are you use at least one Bluetooth wireless peripheral with your Mac. Many Mac users have a Magic Mouse or a Magic Trackpad paired with their desktop Macs. Many also have wireless keyboards, speakers, phones, or other devices connected through a Bluetooth wireless connection.

Bluetooth is convenient for peripherals that are always connected to your Mac and those you use only occasionally. However, Bluetooth connectivity can cause problems when things stop working as expected. These fixes can help.

Information in this article applies to Macs with macOS Catalina (10.15) through macOS High Sierra (10.13), but most of the fixes also work in older versions of the operating system.

В чём суть проблемы

Суть проблемы в том, что внезапно во время работы «отваливаются» Bluetooth-клавиатура и трекпад. Просто теряется связь на ровном месте. После этого приходится перезагружать iMac, чтобы восстановить связь. Но иногда через несколько минут, а иногда через несколько часов снова та же проблема. Чаще всего аксессуары не работают после того, как выходишь из режима сна. Странный баг. Причём он появился на ровном месте — я не ставил новые программы, не менял настройки.

У меня то же самое

Bluetooth is not working on macOS Monterey

After installing the new macOS, things can slow down on your Mac. So you might need a tool that would free up some RAM and fix performance issues.

CleanMyMac X

So, here’s a tip: Download a free version of CleanMyMac X — it’s notarized by Apple on macOS Monterey. It runs maintenance scripts, optimizes your storage, and speeds up your Mac.

Features described in this article refer to the MacPaw site version of CleanMyMac X.

macOS Monterey is loaded with a slew of new features. But, like most macOS, it also has its share of bugs and kinks that need to be worked out.

If you’re having Monterey Bluetooth problems, then you’re in the right place. This article will walk you through fixes for a few of the more common Bluetooth problems in Monterey.

What’s been reported so far:

  • Bluetooth radio not working on Monterey
  • Bluetooth signal dropping off
  • USB-adapter gets disconnected
  • Bluetooth is slow

Update your Monterey version

If you haven’t already, this step may fix it instantly because Apple keeps releasing new patches with fixes for Monterey.

Go to System Preferences > Software Update.

Run macOS Monterey maintenance scripts

Maintenance scripts are something your macOS runs on its own to polish the performance. They optimize certain databases and check for errors. Usually, the macOS runs them once a month or with some other regularity. But you can use a tool to force run these maintenance scripts; for example, CleanMyMac X has such a tool.

After you download the free version of CleanMyMac X and install it, follow these steps:

  1. Open CleanMyMac X.
  2. Choose Maintenance from the sidebar.
  3. Select Run Maintenance Scripts, then click Run.

Bluetooth devices not showing up in Monterey

If you’re trying to connect your Mac to a Bluetooth device, but it’s not showing up in the Bluetooth menu. One quick fix for this is to reset your Bluetooth module. Which I promise sounds scarier than it actually is. Here’s how you do that:

  1. Hold down Shift + Option on your keyboard and click the Bluetooth icon in your toolbar.
  2. Then, click Reset the Bluetooth module.
  3. Click Ok to confirm.
  4. Now try repairing your device.

Some users report that they don’t see the «Reset the Bluetooth module» option on 12.0.1 version of macOS Monterey. If that’s the case — another way to reset your Bluetooth is to open the Terminal and hit this command: sudo pkill bluetoothd

“Bluetooth not available” message

When you try to connect your device, you might be getting an error message that says, “Bluetooth not available.” That could be caused by a bad plist or preference file making your Bluetooth not work right. To reset your Bluetooth plist file, you just need to:

  1. Close any app that’s trying to use Bluetooth.
  2. Open Finder.
  3. Hold down the Option key and click Go > Library > Preferences.
  4. Find the com.apple.Bluetooth.plist file and delete it.
  5. Restart your computer.

Bluetooth won’t turn on

Sometimes after updating to macOS Monterey, if you can’t turn your Bluetooth back on, it’s likely because of something in your SMC.

SMC is a System Management Controller that is in charge of many hardware settings like keyboard lighting and Bluetooth.

Resetting your SMC is easy, but it varies depending on what type of Mac you have. Use the instructions that best match your computer.

Reset the SMC on Macs with non-removable batteries

  1. Turn your Mac off.
  2. Hold control + Option + Shift and the Power button for about 10 seconds.
  3. Release the keys and then, turn your Mac back on.

Reset the SMC on desktop Macs

  1. Shut down your Mac.
  2. Pull out the power cord and slowly count to 15.
  3. Plug the power cable back in and wait five more seconds.
  4. Then, start up your Mac.

Bluetooth keeps disconnecting on Monterey

After you update to macOS Monterey, your Bluetooth devices might continuously disconnect from your computer. One of the other devices that pairs with your computer might be causing a conflict. So, you’ll want to remove all devices and repair them as you need each one. Here are the steps you need to follow to remove your devices.

  1. Hold down Option + Shift and click on the Bluetooth icon.
  2. Click Remove all devices.
  3. Then, click Ok to confirm.

Disable the “Hide your IP” feature

The latest Safari version in macOS Monterey has a tool for hiding your IP address. It gives you some security but is reported to slow things down, even if you use other browsers, like Chrome.

  • Open Safari Preferences.
  • Navigate to Privacy.
  • Uncheck Hide IP address from trackers

Flush your DNS cache

For this last tip we’ll use CleanMyMac X again. This popular Mac maintenance app has a feature to reset the DNS cache (domain name service). Basically, DNS matches websites with their domain names in numeric form. Flushing the DNS cache often gets the internet back to normal.

  • Open CleanMyMac X (download the app here for free)
  • Click on the Maintenance tab.
  • Choose Flush DNS cache and click Run.

Check if your Bluetooth is working again.

Bluetooth devices are designed to make your life easier when using your computer. But it can be equally as frustrating when they aren’t working for you. Hopefully, after reading this article, you’re able to get all of your Bluetooth devices talking with macOS Monterey without any issues.

Understanding the macOS Bluetooth Icon

If you’ve enabled the Bluetooth menu bar icon as mentioned earlier, you’ll see the Bluetooth logo there all the time. You can click it to quickly toggle Bluetooth, connect to a device, or open the full preferences panel.

Depending on the status of Bluetooth, you’ll see the icon change. A plain icon signifies that Bluetooth is turned on. Meanwhile, if Bluetooth is turned off, you’ll see a slash through the Bluetooth logo.

In prior versions of macOS, the Bluetooth icon had other visual changes to communicate useful information. Unfortunately, Apple removed these in macOS Big Sur.

On older versions of macOS, you’ll see the Bluetooth icon with three dots over it when you have at least one Bluetooth device connected to your Mac. You may also see a zigzag line over the icon when there’s a problem with Bluetooth. If you see this, restart your Mac, then proceed to walk through Bluetooth troubleshooting as covered below if you still have problems.

Intel Bluetooth not working in macOS 12 Monterey #295

Bluetooth cannot be turned on. I’m using the latest version of both kexts.

This isn’t limited to Intel Bluetooth. Seems like it effects basically all third party Bluetooth from what I’ve seen in another places. May be an apple bug, in which case it’d be best to wait until closer to release.

8itCat commented Jun 8, 2021

@1Revenger1 so is there any fix yet? Or just hold on while people figure something out?

1Revenger1 commented Jun 8, 2021

8itCat commented Jun 8, 2021

Alright thanks for the quick reply. Do you know the exact cause?

kidonng commented Jun 9, 2021

Nice work @hexart. Does that mean that Intel Bluetooth is on the horizon.

Maybe not yet, bluetoothd still crashes whenever it requests a scan.

pigworlds commented Jun 15, 2021

Looks like the latest firmware update in commit c52425f is not working properly in macOS Monterey. By reverting the firmware to its previous version, it is working on my setup.

To make Intel Bluetooth working in Monterey, following are needed:

  • Latest version of Lilu (from source)
  • Latest version of BrcmPatchRAM (from source), only need BlueToolFixup.kext in this package
  • IntelBluetoothFirmware.kext with older firmware (Can be built from https://github.com/pigworlds/IntelBluetoothFirmware/tree/revertfw)
  • IntelBluetoolInjector.kext is not needed.
  • Shutdown and restart machine instead of reboot.

Tested on Wireless-AC 8265 and Wireless-AC 9560 with streaming audio to Bluetooth headset.

1Revenger1 commented Jun 15, 2021 •

Interesting — works on my AC 9560 as well. Was able to hook up my Magic Trackpad 2 just fine. It still has some issues with turning back on though if you turn it off.

Edit: using nvram bluetoothHostControllerSwitchBehavior=»never» to spoof broadcom doesn’t work either, completely breaking it. Thought it would do something similar to attaching BroadcomBluetoothHostControllerUSBTransport in previous versions.

8itCat commented Jun 15, 2021

@pigworlds @1Revenger1 tested and is working on my Intel AX201. Interesting how such an odd configuration works out!

zxystd commented Jun 15, 2021

Great discovery! It seems that Monterey doesn’t support BT 5.1 and BT 5.2, so new firmwares is not supported, caused 718 error code(HCIERROR) error.
I still believe it is a bug about the new macOS version. But we can downgrade the firmwares to BT 5.0 for a temporary solution.

pigworlds commented Jun 15, 2021

That’s a good point and this sounds like the bug in macOS 12.

On the side, I checked the spec of recent MacBook Pro (16-inch, 2019), MacBook Pro (13-inch, M1, 2020), they only support Bluetooth 5.0 wireless technology. There is no point for Apple to add support Bluetooth 5.1 and 5.2 for Intel devices that doesn’t exist in the market today.

You can merge my branch if you think it is worth to downgrade the firmware temporarily for now.

zxystd commented Jun 15, 2021

@pigworlds That’s kind of funny, Apple support BT 5.1(unless display in the panel) in Bigsur 11.4, so now in new version OS it rollback to BT 5.0.

pigworlds commented Jun 15, 2021 •

What’s the BT version before/after the commit c52425f?

When I load the downgraded firmware, the system profiler shows 5.1 with Wireless-AC 9560, and 4.2 with Wireless-AC 8265 in Big Sur. This lead me believe the system profiler is just reading the version from the device firmware. This means the downgraded firmware also support BT 5.1. I am not sure if the downgraded firmware make difference to the BT version.

zxystd commented Jun 15, 2021

@pigworlds Initial support for BT gen2 is BT 5.0, and 3a9fd05 is BT 5.1 and the last firmware update is BT 5.2.

8itCat commented Jun 15, 2021

Will this become a release @zxystd or should we just build the kexts ourselves? Nice work btw!

zxystd commented Jun 15, 2021

@AvaQueen-Official will release version 1.1.3 soon.

Thanks for the information!

kidonng commented Jun 16, 2021

Very interestingly, with @pigworlds’s setup I can use my Bluetooth 4.x mouse again. Yeah I’m aware of #51, but actually I have no (serious) issues until macOS 11.4, when I couldn’t connect to the mouse at all.

This comment has been hidden.

pigworlds commented Jun 18, 2021

Here is another fact I discovered: I updated the firmware to the latest version from Linux (specifically this commit as I’m using Intel 9461) and it still works. So I guess there could also be a firmware issue.

Can anyone else test if this build works?

I am unable to make it work with this build on Wireless-AC 9560. Did you shut down the machine between test to make sure the expected firmware is loaded?

kidonng commented Jun 18, 2021 •

Yup, my fault. I did shutdown, but now I inspected further and found that the system is still using the old Firmware kext. Sorry for the disturbance!

This also works with my AX201. BlueTool + IntelFirmware (no injector).

This seems to be busted again in beta 10

Hi @pigworlds,
I tried your post solution. my environment is:
Monterey 12.0.1,
opencore 0.7.4,
Bluetooth device: intel 9560.

so just downloaded the IntelBluetoothFirmware: 1.1.3
and downloaded bluetoolfixup.kext latest version.

When I shut down the system and boot it again, but the Bluetooth is not working.

before, when I prepare to upgrade Monterey from big sur, I worry about the upgrade processing being stuck, I remove two kexts IntelBluetoothFirmware.kext and IntelBluetoothInjector.kext, and close the Bluetooth.

Is that why I can’t apply your solution right now?

Подскажете пожалуйста, как реализована система переключение между Bluetooth и AUX, на китайских платах вот такого типа

вот описание (Модуль поддерживает беспроводной Bluetooth прием и один AUX аналоговый аудио вход для переключения выходного сигнала. Реле используется для переключения без потерь, что никак не повлияет на качество звука. Модуль по умолчанию переходит в режим AUX line, и режим переключения-это автоматическое переключение, с приоритетом Bluetooth.)

Гость Иван

Имеется магнитола Sony, модуль Bluetooth BT5.0 audio pro, с соединением звука и питания проблем не возникло. Припаялся к ауксу и питание с usb порта, все работает. На модуле есть 3 кнопки, нужно хотя бы одну, которой треки вперед щелкать. Схему модуля не нашел, схему панельки магнитолы прилагаю. Пробовал замыкать массу платы магнитолы на выход кнопки переключения треков блютуза, переключает. Но, как я понял, если подпаяться так, как на картинке (простите за такое похабное изображение) то треки будут переключаться любой кнопкой (которые в этой цепочке и висят на контакт key0) на панели магнитолы. От этого можно как-то уйти?

LG FFH 868AX.pdfЗдравствуйте. Достался мне на халяву муз.центор -лыжа ffh 868. Там даже не мп3 . Там сд ченьжер. Причем не рабочий. Ну думаю закажу на Алишке блютуз модуль и устанавлю сам. Насмотревшись ютюба, я своими «кривыми» ручками, (а по профессии я тракторист машинист широкого профиля) разобрал центр и начал искать 12в. Тыкнул мультиметром;один на корпус, другой в один из пинов шлейфа идущий на СД , щюп соскальзнул икоротнул ближайшей пин. Был щелчёк, похожий на челчёк реле. Центр потух. Не реагирует на вкл. Помогите плиз. Что могло выйте из строя , что звонить Схему ташол. Попытаюсь выложит место где коротнул

Всем привет, имею аудиосистему microlab a6600 (a6601 такая же), система 5:1, хочу сделать её без проводной, чтобы передача аудиосигнала передавала на усилитель не через провод jack 3.5, а к примеру заказать модуль Bluetooth на алиэкспрессе и припаять, что скажете, реально ли так сделать
