You can connect a mouse to your MacBook using Bluetooth or a USB cable, and the process takes less than a minute

A MacBook trackpad works well for most tasks, but many people prefer a mouse for longer work sessions or precise clicking. Your MacBook supports both wireless and wired mice. Bluetooth mice connect without cables and work from across a room. Wired USB mice plug directly into a port and start working immediately. Either way, the connection process is straightforward and requires no special software.

The method you choose depends on what you have available and how you work. Bluetooth mice give you freedom to move around without a cable, but they need charging or battery replacement. Wired mice start working the moment you plug them in and never run out of power, but the cable limits how far you can sit from your MacBook.

Key Takeaways

  • Bluetooth mice pair through System Settings and work wirelessly, while USB mice plug into a Thunderbolt or USB-C port and work right away.
  • To pair a Bluetooth mouse, turn it on, open System Settings, select Bluetooth, and click the mouse name when it appears in the list.
  • If your mouse does not appear in Bluetooth settings, make sure it is turned on and in pairing mode, which usually means holding a button for three seconds.
  • Wired mice work immediately after plugging in, but you may need a USB-C adapter if your MacBook has only Thunderbolt ports.

Connecting a Bluetooth mouse to your MacBook

Turn on your mouse and put it in pairing mode. Most Bluetooth mice have a small button on the bottom or side that you hold for about three seconds until a light blinks. Check your mouse manual if you are unsure which button to press — different brands use different methods. Some mice enter pairing mode automatically when you turn them on for the first time.

Open System Settings on your MacBook. Click the Apple menu in the top-left corner, then select System Settings. In the sidebar, click Bluetooth. Your MacBook will start searching for nearby devices. When your mouse appears in the list, click it. Your MacBook will connect and the mouse is ready to use. You do not need to repeat this process — your MacBook will remember the mouse and connect automatically the next time you turn it on.

If your mouse does not appear after 30 seconds, make sure the mouse is turned on and still in pairing mode. Some mice exit pairing mode after a minute. Try holding the pairing button again and wait for the light to blink. If the mouse still does not show up, restart your MacBook and try again.

Connecting a wired USB mouse to your MacBook

Plug the mouse cable into a USB port on your MacBook. Newer MacBooks have Thunderbolt ports instead of traditional USB ports. If your mouse has a standard USB connector and your MacBook only has Thunderbolt ports, you will need a USB-C to USB adapter. These adapters cost between $15 and $25 and are available from Apple or third-party retailers.

Once plugged in, the mouse works immediately. Your MacBook recognizes it as an input device and you can start using it right away. No pairing or setup is required. If you want to unplug the mouse and use your trackpad instead, simply disconnect the cable. The mouse will work again the next time you plug it in without any additional steps.

What to do if your mouse is not working after connecting

For Bluetooth mice, check the battery level first. Most Bluetooth mice have a battery indicator light or a way to check the battery in System Settings. Open System Settings, click Bluetooth, find your mouse in the list, and look for a battery percentage next to its name. If the battery is low, charge the mouse using its charging cable or replace the batteries if it uses disposable ones.

If your mouse is connected but the cursor is not moving, try restarting your MacBook. Sometimes the connection drops and a restart fixes it. You can also remove the mouse from your Bluetooth devices and pair it again. Open System Settings, click Bluetooth, find your mouse, click the information icon next to its name, and select Remove. Then turn the mouse off and on again, put it in pairing mode, and pair it fresh.

For wired mice, make sure the cable is fully inserted into the port. Try a different USB port if one is available. If you are using an adapter, try a different adapter to rule out a faulty one. Restart your MacBook if the mouse is plugged in but not responding.

Adjusting mouse settings after connection

Once your mouse is connected, you can customize how it behaves. Open System Settings, then click Mouse in the sidebar. You can adjust the tracking speed — how fast the cursor moves when you move the mouse — and the clicking speed. Some mice also have additional buttons that you can customize here. Experiment with the tracking speed to find what feels comfortable for your work.

If you have a mouse with a scroll wheel, you can control whether scrolling direction matches your trackpad or reverses it. This setting is in System Settings under Mouse. You can also enable or disable secondary click, which lets you right-click with the mouse button instead of using a keyboard shortcut. These adjustments take effect immediately and you can change them anytime.

Switching between your mouse and trackpad

Your MacBook lets you use both your mouse and trackpad at the same time. You do not have to choose one or the other. If you connect a mouse and later want to use just your trackpad, simply move away from the mouse or let it go to sleep. Your trackpad will work normally. When you move the mouse again, it wakes up and takes over.

If you want to disable your trackpad entirely while using a mouse, open System Settings, click Trackpad, and uncheck "Tap to click" or other trackpad features. This prevents accidental touches on the trackpad from interfering with your mouse work. You can turn these settings back on anytime if you need your trackpad again.

Frequently Asked Questions

Can I use any mouse with a MacBook?

Most mice work with MacBooks, but some gaming mice or mice designed for Windows may have limited functionality. Bluetooth mice and standard USB mice are your safest choices. Check the product description to confirm Mac compatibility before buying.

Why does my Bluetooth mouse keep disconnecting?

Low battery is the most common cause. Charge your mouse and check the battery level in System Settings. If the battery is full and it still disconnects, try removing and re-pairing the mouse. Interference from other Bluetooth devices can also cause drops — move other wireless devices away from your MacBook.

Do I need to install drivers for my mouse?

Most mice work without drivers on macOS. Standard Bluetooth and USB mice are recognized automatically. Some specialty mice from brands like Logitech or Razer include their own software for extra features, but this is optional. Your mouse will work without it.

Can I connect multiple mice to one MacBook?

Yes. You can pair several Bluetooth mice and switch between them by turning each one on or off. Only one mouse will work at a time, but you can have multiple mice paired to your MacBook for convenience.

What is the difference between a trackpad and a mouse?

A trackpad is built into your MacBook and responds to finger touch. A mouse is a separate device you move with your hand to control the cursor. Many people find mice more precise for detailed work or less tiring for long sessions, but trackpads are portable and require no extra equipment.
