The basic steps to pair a Bluetooth mouse

To connect a Bluetooth mouse to your MacBook, you turn on the mouse, open System Settings on your Mac, go to Bluetooth, and select the mouse from the list that appears. The mouse and MacBook then exchange a small amount of data to confirm they recognize each other — this is called pairing. Once paired, the mouse connects automatically whenever both devices are turned on and in range.

The whole process usually takes under a minute. After pairing, you do not need to repeat these steps; your MacBook will remember the mouse and reconnect it the next time you use it.

Key Takeaways

  • Turn on your Bluetooth mouse and make sure it has working batteries or is charged.
  • Open System Settings, click Bluetooth in the sidebar, and wait for your mouse to appear in the list of available devices.
  • Click your mouse's name in the Bluetooth list to pair it — no password is needed for most mice.
  • Once paired, your MacBook will reconnect to the mouse automatically each time you turn it on.

Before you start: what you need

Your mouse must have Bluetooth built in — not all mice do. If your mouse came with a small USB receiver (a tiny dongle that plugs into your Mac), it uses a different wireless technology and does not pair through Bluetooth. Check your mouse's manual or the box it came in to confirm it says "Bluetooth" or "wireless".

Make sure your mouse has power. If it uses batteries, install fresh ones or check that they are not dead. If it is rechargeable, plug it in for a few minutes. A mouse with no power will not show up in your MacBook's Bluetooth list, and you will think something is broken when it is not.

Step-by-step pairing instructions

Step 1: Turn on your mouse. Look for a power button, usually on the bottom or side. Some mice have an on/off switch; others turn on automatically when you move them. Check the manual if you are not sure where the button is.

Step 2: Open System Settings on your MacBook. Click the Apple menu in the top-left corner of your screen, then select "System Settings" (or "System Preferences" if you have an older Mac). On the left side, you will see a list of categories.

Step 3: Click Bluetooth in the sidebar. You will see a list of devices your Mac has paired with before, and below that, a section called "Available devices" showing devices nearby that are not yet paired.

Step 4: Wait for your mouse to appear. It may take 10 to 15 seconds. If your mouse does not show up, make sure it is turned on and close to your MacBook. If it still does not appear, try turning the mouse off and on again.

Step 5: Click your mouse's name. When it appears in the "Available devices" list, click it once. Your MacBook will pair with it automatically — you do not need to enter a password or code.

Step 6: Confirm the pairing is complete. Your mouse's name will move from "Available devices" to the top section showing connected devices. You should now be able to move your mouse and see the cursor move on your screen.

What to do if your mouse does not appear

If your mouse is not showing up in the Bluetooth list, the most common reason is that it is not turned on or the batteries are dead. Turn it off, wait five seconds, turn it back on, and check the Bluetooth list again. Some mice have a small LED light that blinks when they are searching for a device to pair with — if you see that light, your mouse is in pairing mode and should appear within 15 seconds.

If the mouse still does not appear, try restarting your MacBook. Sometimes the Bluetooth system needs a fresh start. Shut down your Mac completely, wait 30 seconds, and turn it back on. Then open System Settings and Bluetooth again.

If your mouse has a pairing button (a small button you hold down for a few seconds), press it while the Bluetooth list is open on your Mac. This puts the mouse into a mode where it broadcasts its presence more loudly, and your MacBook should find it right away.

Reconnecting after the first time

Once you have paired your mouse, you do not need to go through System Settings again. The next time you turn on your mouse and MacBook, they will recognize each other and connect on their own. This happens in the background — you will just notice the cursor starts responding to your mouse movements.

If your mouse does not reconnect automatically, make sure both devices are turned on and within about 30 feet of each other. Bluetooth has a limited range, and walls or other obstacles can weaken the signal. If you move your mouse far away from your Mac, the connection may drop, but it will reconnect when you bring them close again.

Disconnecting or removing a mouse

If you want to stop using a Bluetooth mouse, you can straightforward turn it off. Your MacBook will not try to reconnect. If you want to remove it completely so it no longer appears in your Bluetooth list, open System Settings, click Bluetooth, find the mouse in the list, and click the X or "Remove" button next to its name. You can always pair it again later by following the steps above.

This is useful if you are giving the mouse to someone else or switching to a different mouse and do not want your MacBook to keep trying to connect to the old one.

Frequently Asked Questions

Do I need a password to pair a Bluetooth mouse?

No. Most Bluetooth mice pair without any password or code. Your MacBook and mouse exchange information automatically. If a password is requested, something unusual is happening — check your mouse's manual or try restarting both devices.

Can I use more than one Bluetooth mouse with my MacBook?

Yes, you can pair multiple mice to your MacBook. Only one will be active at a time, but you can switch between them by turning one off and turning another on. This is useful if you have a mouse at your desk and a portable one for travel.

Why does my mouse keep disconnecting?

The most common reason is low battery power. Replace the batteries or recharge the mouse. If that does not help, move your mouse closer to your MacBook — Bluetooth works best within 30 feet and without obstacles between the devices. If disconnections continue, try removing the mouse from your Bluetooth list and pairing it again from scratch.

What is the difference between Bluetooth and a USB wireless mouse?

A Bluetooth mouse connects directly to your Mac without any extra hardware. A USB wireless mouse uses a small receiver that plugs into your Mac's USB port. Bluetooth is cleaner (no dongle to lose) but uses slightly more battery power. Both work well — it depends on what your mouse supports.

Can I use a Bluetooth mouse with other devices besides my MacBook?

Yes. Once you pair a Bluetooth mouse with your MacBook, you can also pair it with an iPhone, iPad, or other device. The mouse remembers multiple pairings and will connect to whichever device is closest or turned on. You can only use it with one device at a time, but switching is straightforward.
