If your mouse or keyboard--especially a Magic Mouse or wireless keyboard--suddenly stops connecting to your Mac, it can disrupt your workday in a flash. This practical guide walks you through troubleshooting steps to fix the issue.
1. Check Power and Battery Levels First
- Magic Mouse or Apple Wireless Keyboard: Make sure the device is switched _on_.
- Rechargeable Models: Plug them in via a Lightning cable for at least 5-10 minutes.
- Battery-Operated Devices: Swap out the batteries with fresh ones.
If you're using a USB mouse or keyboard, try a different port.
2. Ensure Bluetooth Is Turned On
- Go to System Settings > Bluetooth.
- Confirm that Bluetooth is ON.
- If your device is listed as "Not Connected," click Connect.
3. Restart Your Mac
- Press Control + Command + Power to force a restart.
- If frozen, hold the Power button until your Mac shuts down.
4. Reset Bluetooth Module (Intel Macs Only)
- Hold Shift + Option and click the Bluetooth icon in the menu bar.
- Choose Reset the Bluetooth module.
- Select Remove all devices, then re-pair.
5. Plug In a Temporary USB Keyboard or Mouse
Use a standard USB or USB-C keyboard/mouse as a workaround.
6. Install macOS Updates
Go to System Settings > General > Software Update.
7. Unpair and Re-Pair Devices
- Navigate to System Settings > Bluetooth.
- Hover over the device name, click the "i" icon, then select Forget.
- Restart your Mac and re-pair the device.
8. Try Safe Mode or Reset NVRAM
- Safe Mode: Restart and hold Shift while booting.
- Reset NVRAM: Hold Option + Command + P + R for 20 seconds during startup.
9. Look for Wireless Interference
Bluetooth connections can be disrupted by microwaves, Wi-Fi routers, wireless phones, and other Bluetooth devices.
