The fastest way: use Bluetooth

Most mice sold today connect to a MacBook wirelessly through Bluetooth, which is a short-range radio connection built into every MacBook. This is the simplest route because you do not need cables or adapters — you just turn on the mouse, hold down its pairing button, and tell your MacBook to recognize it.

The mouse and MacBook talk to each other once, and after that the mouse reconnects automatically whenever you turn it on. This pairing happens in the Bluetooth settings on your Mac, which you reach by clicking the Apple menu in the top-left corner, then System Settings, then Bluetooth.

Key Takeaways

  • Bluetooth mice connect wirelessly and pair once through your MacBook's Bluetooth settings, then reconnect automatically each time you turn them on.
  • USB mice plug into a Thunderbolt or USB-C port on your MacBook and work when ready without any setup.
  • If your mouse uses a USB receiver (a small wireless dongle), you need a USB-C adapter because modern MacBooks do not have standard USB ports.
  • A trackpad or Magic Mouse works the same way as any other mouse but also lets you use MacBook-specific gestures like swiping with multiple fingers.
  • If your mouse does not appear in Bluetooth settings, restart both the mouse and your MacBook, then try pairing again.

Pairing a Bluetooth mouse step by step

First, make sure your mouse has batteries and is turned on. Most Bluetooth mice have a small power switch on the bottom. Then look for a pairing button — this is usually on the underside or the back, and the manual that came with the mouse will tell you where it is. Hold down that button for three to five seconds until a light on the mouse starts blinking.

On your MacBook, open System Settings. Click Bluetooth in the left sidebar. You should see your mouse listed under "Available Devices" or "Other Devices". Click it, and your MacBook will ask you to confirm the pairing. Click Pair. The mouse should now appear under "Connected" or "My Devices", and the blinking light should stop.

From now on, when you turn on the mouse, it will reconnect to your MacBook automatically. You do not have to pair it again unless you pair it with a different computer or you unpair it manually in Bluetooth settings.

Using a wired USB mouse instead

If your mouse has a USB cable, you can plug it directly into your MacBook. Modern MacBooks have Thunderbolt 3 or Thunderbolt 4 ports, which look like small oval slots. A standard USB mouse cable will not fit into these ports, so you need a USB-C to USB-A adapter — a small piece that costs ten to fifteen dollars and lets you plug a regular USB cable into your MacBook's Thunderbolt port.

Once you plug in the mouse, your MacBook recognizes it when ready. There is no pairing step, no settings to change. The mouse works right away. When you unplug it, the connection stops. This route is useful if you do not want to manage batteries or if you want a mouse that is always ready without waiting for it to reconnect.

Wireless mice with a USB receiver

Some wireless mice come with a small USB receiver — a dongle about the size of a thumb drive that plugs into your computer and lets the mouse talk to it without Bluetooth. These mice are common and often cheaper than Bluetooth mice. To use one with a MacBook, you need a USB-C to USB-A adapter, just like you would for a wired mouse.

Plug the adapter into a Thunderbolt port on your MacBook, then plug the receiver into the adapter. Turn on the mouse. The receiver and mouse pair automatically at the factory, so the mouse should work when ready — you do not have to do anything in System Settings. The mouse will reconnect to the receiver whenever you turn it on, as long as the receiver stays plugged in.

Connecting Apple's Magic Mouse or trackpad

Apple's Magic Mouse and Magic Trackpad are Bluetooth devices that pair the same way as any other Bluetooth mouse — through System Settings, Bluetooth. They work like a regular mouse, but they also respond to gestures: you can swipe with two fingers to scroll, pinch to zoom, or swipe with three fingers to move between open windows. These gestures only work on Apple's own input devices, not on third-party mice.

Magic Mouse and Magic Trackpad both charge through USB-C cables, not batteries. You charge them by plugging a USB-C cable into the port on the bottom, which takes about two hours for a full charge. The battery lasts about a month of normal use before you need to charge again.

Troubleshooting when your mouse will not connect

If your mouse does not appear in Bluetooth settings, first check that it is turned on and has batteries. Then restart the mouse by turning it off and back on. If it still does not appear, restart your MacBook — sometimes Bluetooth needs a fresh start. After your MacBook restarts, turn on the mouse and hold down its pairing button again.

If the mouse appears in Bluetooth settings but does not respond to clicks, try clicking "Forget This Device" next to the mouse's name in Bluetooth settings, then pair it again from scratch. If you are using a USB receiver and the mouse does not work, make sure the receiver is fully plugged in and that you are using a working USB-C adapter. Try plugging the receiver into a different Thunderbolt port on your MacBook.

For a wired USB mouse that does not work, try a different USB-C adapter — the one you are using may be faulty. If you have access to another MacBook or computer, test the mouse there to confirm the mouse itself is working.

Frequently Asked Questions

Can I use a mouse made for Windows on a MacBook?

Yes. Any mouse that uses Bluetooth or a USB receiver will work on a MacBook, regardless of whether it was designed for Windows or Mac. The only difference is that some Windows mice have extra buttons that MacBook software may not recognize, but the basic left-click and right-click will always work.

Do I need to install software or drivers for my mouse?

Most mice do not need any software. Bluetooth mice and USB mice work when ready. Some gaming mice or mice with many extra buttons come with software that lets you customize what each button does, but this is optional — the mouse will work without it.

Can I connect multiple mice to one MacBook?

Yes. You can pair as many Bluetooth mice as you want, and your MacBook will remember all of them. Only one mouse can be active at a time, but you can switch between them by turning one off and turning another on. You can also use a mouse and trackpad together — your MacBook will respond to whichever one you use.

Why does my Bluetooth mouse keep disconnecting?

This usually means the mouse batteries are low. Replace them and see if the problem stops. If the mouse still disconnects, try moving it closer to your MacBook — Bluetooth works best within about thirty feet, but obstacles like walls or metal can weaken the signal. You can also try forgetting the mouse in Bluetooth settings and pairing it again.

What if my MacBook does not have Bluetooth?

Every MacBook made in the last ten years has Bluetooth built in. If you have an older MacBook and Bluetooth is not working, you can use a wired USB mouse with a USB-C adapter, or you can buy a USB Bluetooth adapter that plugs into your MacBook's Thunderbolt port.
