Start with the simple stuff

Before we get into the troubleshooting steps, it’s best to start with the basics. And it really doesn't get any more basic than switching things off and on again.

While this seems like a lazily obvious suggestion, a lot of Mac problems can be fixed with a restart.

Click on the Bluetooth icon in the menu bar and select the option to Turn Bluetooth Off. Once it’s switched off, turn it back on by clicking on Turn Bluetooth On.

If the macOS or OSX “Bluetooth Not Available” error hasn’t gone away, try rebooting your Mac. Shut the system down completely and reboot it as usual.

Get a tool for Bluetooth switching

There’s an easier way to toggle Bluetooth on Mac, though. At least two ways, actually. You can have a dedicated app for connecting Bluetooth gadgets, ToothFairy. It allows you to create a custom setup for any number of your Bluetooth devices.

If there are not really too many Bluetooth devices you use regularly, go with One Switch — a set of dedicated toggles accessible from the menu bar. You can add a device once, and use the app for one-click Bluetooth toggling every time.

If that doesn’t work, it’s time to get down to some real troubleshooting. Here are five of the best tips to help you overcome annoying Bluetooth issues.

Five Tips to solve Bluetooth problems

1. Delete downloads

Have you downloaded any new applications or software programs recently? One of them could be corrupting your Bluetooth. It could be malware that’s causing the issue or simply an app that does sit right with Apple’s Bluetooth configuration. Either way, it’s best to remove any recently downloaded files to rule them out if nothing else.

The easiest way to do this is with CleanMyMac X. It requires nothing more than a few clicks and completely removes every file linked to a download.

Here’s how to use it:

1. Download CleanMyMac X and launch it.
2. Click Large & Old Files.
3. Select the recent downloads you wish to remove.
4. Click Clean and the files will be gone in the blink of an eye.

If you’d prefer to delete downloads manually, you can do this in the Finder.

1. Open the Finder.
2. Press Cmd+Shift+G.
3. Type in ~/.
4. Double-click on the Downloads folder.
5. Delete any downloaded file that you don’t need.

If you’ve installed an app related to a downloaded file and you’re worried that’s what might be causing issues with your Bluetooth, use CleanMyMac X to completely remove it:

1. Launch CleanMyMac X.
2. Click on Uninstaller.
3. Select the app that you want to remove from the list.
4. Click Uninstall.

2. Remove all USB devices

Apple is aware that Bluetooth connectivity is an issue for Mac users and has a dedicated support page for Mac mouse problems, as well as possible fixes for unresponsive keyboards and trackpads.

One quick fix to kick the Bluetooth back into life is to disconnect all USB devices. Remove any and all USB keyboards, mice, and external drives and reboot your Mac. Wait for a couple of minutes and then reconnect them.

It’s a quirky tip, but it might be all it takes to restore the Bluetooth connection.

2. Reset the SMC if Bluetooth is not available on Mac

Resetting the System Management Controller (SMC) is the go-to troubleshooting tip for any issues related to Mac hardware or software, and it usually works.

The process is different depending on which type of Mac you’re using, but we’ve got you covered with both methods:

Resetting the SMC (non-removable batteries)

1. Shut down your MacBook.
2. Plug in the power adapter.
3. Hold Shift+Control+Option and the Power button at the same time for around 10 seconds.
4. Release the keys at the same time.
5. Boot up your Mac as usual.

Resetting the SMC (removable batteries)

1. Shut down your MacBook and remove the battery.
2. Disconnect the power adapter.
3. Hold down the Power button for 10 seconds and release.
4. Reconnect the battery and power adapter.
5. Boot up your Mac as usual.

Resetting the SMC if iMac, Mac mini, or Mac Pro

1. Shut down your Mac.
2. Disconnect the power cord.
3. Hold down the Power button for 5 seconds and release.
4. Reconnect the power cord.
5. Boot up your Mac as usual.

3. Delete .plist files

.plist (Property List) files are used by Macs to store software user preferences for things like the keyboard, mouse, and trackpad. It’s rare, but not unheard of, for these files to become corrupted and affect Bluetooth connectivity. Deleting the .plist files is a straightforward process.

1. Close any app that is trying to connect with Bluetooth.
2. Press Command+Shift+G in the Finder.
3. Enter ~/Library/Preferences/ and click Go.
4. Locate the com.apple.Bluetooth.plist file and delete it.
5. Reboot your MacBook.

The Preferences folder might contain other files with the same extension. It’s safe to delete these too but start with the com.apple.Bluetooth.plist file first.

4. Reset the Bluetooth module

If none of the above troubleshooting tips have worked, it’s time to reset the Bluetooth module. Doing this will attempt to debug any issues.

1. Hold Shift+Option and click on the Bluetooth menu in the Mac menu bar.
2. Click Debug and select Remove all devices.
3. Click Debug again and select Reset the Bluetooth module.
4. Restart your Mac.
5. Repair each of your Bluetooth devices.

If you’ve exhausted all of the options it could be that the problem is a serious hardware issue that requires support from AppleCare or an authorized third-party Apple specialist.
