A surprisingly common issue after macOS updates is Bluetooth completely breaking — your Magic Mouse stops responding, the keyboard won't pair, or AirPods refuse to connect even though they worked fine before. The problem often appears after Sequoia or Tahoe updates. Luckily, resetting the Bluetooth module through a simple terminal command usually solves it right away. Follow the steps below.
- Launch Terminal on your Mac — use Spotlight (⌘ + Space) and type "Terminal"
- Copy the command below, paste it into Terminal, and press Enter
- Enter your Mac password when asked (it won't show on screen), then restart your Mac
sudo pmset -a bluetoothCycle 0 && sudo rm -rf /Library/Preferences/com.apple.Bluetooth.plist && sudo pkill bluetoothd && sudo killall bluetoothd
- Forces macOS to completely reset the Bluetooth driver and clear its internal state
- Removes a corrupted Bluetooth preference file that often causes connection failures
- Restarts the Bluetooth daemon so everything starts fresh on next boot
Every major macOS update brings changes to system frameworks, including how Bluetooth handles device pairing and power management. Sometimes the migration process leaves behind corrupted configuration files or the Bluetooth daemon fails to restart properly. The result is that your Mac either can't find nearby devices at all, or it sees them but fails to connect. This has been widely reported on Apple forums after Sequoia, Ventura, and Sonoma updates.
- MacBook Pro (2019–2024) — both Intel and Apple Silicon models show this behavior
- MacBook Air M1 / M2 / M3 — reports spiked after Sequoia release
- Mac mini — external Bluetooth devices like keyboards and mice often disconnect
- iMac — Magic Keyboard and Magic Mouse pairing fails after waking from sleep
- Mac Studio / Mac Pro — less frequent, but the same reset method works
Yes. The command only removes a Bluetooth configuration file (which macOS recreates automatically) and restarts the Bluetooth service. No personal data, documents, or system files are affected. After restarting, your Mac will treat Bluetooth devices as new — you'll need to pair them again, but that's a one-time step. Your Wi-Fi, audio, and other settings stay completely unchanged.
Yes, you will need to pair your Bluetooth devices again after running this command. The reset clears the stored device list because the corrupted preference file is removed. This sounds inconvenient, but it's exactly what makes the fix work — a clean slate allows macOS to rebuild the Bluetooth configuration correctly. On most systems, re-pairing takes less than a minute.
- Hold Shift + Option and click the Bluetooth icon in the menu bar, then select Reset the Bluetooth module
- Go to System Settings → Bluetooth, turn Bluetooth off, wait 10 seconds, and turn it back on
- Shut down your Mac completely (not just restart), unplug all USB devices, wait 30 seconds, then power back on
- Check for macOS updates — Apple sometimes releases Bluetooth‑specific patches in point updates
- If nothing works, reset NVRAM/PRAM (on Intel Macs) by holding Option + Command + P + R during startup
If none of the steps above worked, the issue is likely hardware-related — the built-in Bluetooth chip on your Mac may be damaged or failing. This happens more often on older Intel MacBooks after repeated macOS updates. The simplest fix is a compact USB Bluetooth adapter that bypasses the internal chip entirely and gives you a stable, reliable connection right away.
