While the built-in trackpad and keyboard on a MacBook are excellent, many users prefer the ergonomic comfort and precision of an external wireless mouse and keyboard. If you are using a desktop Mac (like an iMac or Mac mini), external peripherals are an absolute necessity. Bluetooth is the standard wireless protocol used by macOS to connect these devices without the clutter of USB cables or dongles.
Pairing a new Bluetooth device to your Mac only takes a few seconds. Once paired, the Mac will remember the device and automatically connect to it whenever it is turned on and within range.
This guide explains how to properly connect a third-party Bluetooth mouse, keyboard, or trackpad to your Mac.
Step 1: Put Your Device in Pairing Mode
Before your Mac can see the mouse or keyboard, the device must be broadcasting a pairing signal.
- Ensure your mouse or keyboard has fresh batteries or is fully charged.
- Turn the power switch on the device to the ON position.
- Locate the Pairing Button. On most devices, this is a small button on the bottom, often labeled “Connect” or featuring a Bluetooth logo. Press and hold this button until the LED light on the device begins to blink rapidly. Note: If you are using an official Apple Magic Keyboard or Magic Mouse, simply turning them on is usually enough, or you can temporarily plug them into the Mac using a Lightning-to-USB cable to pair them instantly.
Step 2: Connect the Device in macOS
Once the device is blinking and in pairing mode, you can connect it through the macOS system settings.
- Click the Apple Logo in the top-left corner of your screen.
- Select System Settings (or System Preferences on older versions of macOS).
- In the left sidebar, click on Bluetooth.
- Ensure the main Bluetooth toggle switch is turned On.
- Look under the “Other Devices” or “Devices” section. You should see your mouse or keyboard appear in the list. It may take a few seconds to show up.
- Hover your cursor over the device name and click the Connect button next to it.
If you are connecting a keyboard, your Mac may ask you to press a few specific keys (like the key immediately next to your Shift key) so that the operating system can accurately identify the keyboard layout (e.g., ANSI vs. ISO). Follow the on-screen instructions if prompted.
Troubleshooting Connection Issues
If your device does not appear in the Bluetooth menu, or if it fails to connect:
- Toggle Bluetooth: Turn Bluetooth off and back on using the toggle switch in System Settings.
- Check other devices: Ensure the mouse or keyboard is not accidentally connecting to your iPad or another computer in the same room. Unpair it from those devices first.
- Restart your Mac: Sometimes the macOS Bluetooth daemon needs a fresh start. Restart your computer and try the pairing process again.
