Mac Bluetooth Not Working? Here's How to Fix It

Can't connect your AirPods, Magic Mouse, or other Bluetooth devices to your Mac? These fixes work for MacBook, iMac, Mac mini, and Mac Studio.

⏱️ 5-20 min 💪 Easy 💻 All Macs

Common Bluetooth Problems

  • Bluetooth unavailable: Bluetooth icon shows as grayed out or missing
  • Devices won't pair: Mac can't find or connect to devices
  • Keeps disconnecting: Devices connect then drop repeatedly
  • Audio stuttering: Bluetooth audio cuts in and out
  • Mouse/keyboard lag: Input devices respond slowly

Fixes to Try

1 Toggle Bluetooth Off and On

The simplest fix often works:

  1. Click the Control Center icon in the menu bar (two toggles icon)
  2. Click Bluetooth to turn it off
  3. Wait 10 seconds
  4. Click Bluetooth again to turn it back on
  5. Try reconnecting your device

2 Remove and Re-Pair the Device

Corrupted pairing data can cause issues:

  1. Go to System Settings → Bluetooth
  2. Find your device in the list
  3. Click the ⓘ info button next to it
  4. Click Forget This Device
  5. Put your device back in pairing mode
  6. Reconnect from the Bluetooth settings

3 Reset the Bluetooth Module

This clears all Bluetooth settings without losing paired devices:

  1. Hold Shift + Option and click the Bluetooth icon in the menu bar
  2. Select Reset the Bluetooth module
  3. Click OK to confirm
  4. Restart your Mac
Note: If you don't see this option, the hidden debug menu may be disabled in newer macOS versions. Try the next fix instead.

4 Delete Bluetooth Preference Files

Corrupted preference files are a common culprit:

  1. Turn off Bluetooth first
  2. Open Finder and press Command + Shift + G
  3. Type /Library/Preferences and press Enter
  4. Find and delete: com.apple.Bluetooth.plist
  5. Also check ~/Library/Preferences for the same file
  6. Restart your Mac
Tip: You may need to re-pair all your Bluetooth devices after this.

5 Check for Wireless Interference

Bluetooth operates on 2.4GHz and can be disrupted:

  • Move USB 3.0 devices away from your Mac (they emit interference)
  • Move away from microwaves, baby monitors, or cordless phones
  • If using USB-C/Thunderbolt hubs, try connecting devices directly
  • Reduce distance between Mac and Bluetooth device

6 Reset NVRAM (Intel Macs)

NVRAM stores Bluetooth settings that can become corrupted:

  1. Shut down your Mac completely
  2. Turn it on and immediately hold Option + Command + P + R
  3. Hold for about 20 seconds
  4. Release and let Mac boot normally
Apple Silicon Macs: NVRAM resets automatically when needed. Just restart your Mac instead.

7 Update macOS

Apple frequently patches Bluetooth bugs:

  1. Go to System Settings → General → Software Update
  2. Install any available updates
  3. Restart and test Bluetooth

8 Boot in Safe Mode

Test if third-party software is causing conflicts:

Apple Silicon Mac:

  1. Shut down completely
  2. Press and hold power button until "Loading startup options" appears
  3. Select your disk, hold Shift, click "Continue in Safe Mode"

Intel Mac:

  1. Restart and immediately hold Shift
  2. Release when login window appears

If Bluetooth works in Safe Mode, a third-party app is interfering.

Still Not Working?

If none of these fixes work, your Mac may have a hardware issue with the Bluetooth/Wi-Fi module. This is especially common on older MacBooks where the module can fail.
