The fastest way to connect a mouse to your Mac
Most mice connect to your Mac in one of two ways: Bluetooth wireless or a USB cable. Bluetooth is simpler because it requires no physical connection — you turn on the mouse, hold down its pairing button for a few seconds, then select it from your Mac's Bluetooth menu. A USB mouse plugs directly into any USB port on your Mac and works immediately, with no setup needed.
Which one you use depends on what mouse you own. If it came with a USB receiver (a small dongle), that goes in a USB port. If the mouse has a Bluetooth button or came with instructions mentioning pairing, use Bluetooth. If you're not sure, check the box or the manufacturer's website — they'll tell you which method that specific model uses.
Key Takeaways
- Bluetooth mice pair through System Settings > Bluetooth, while USB mice plug in and work immediately without any setup.
- Your Mac's Bluetooth must be turned on before you can pair a wireless mouse, and you may need to hold the mouse's pairing button for three to five seconds.
- If your mouse doesn't appear in the Bluetooth list, restart both the mouse and your Mac, then try pairing again.
- USB mice work with any USB port on your Mac, including USB-C ports with an adapter if your Mac only has USB-C.
Pairing a Bluetooth mouse to your Mac
Open System Settings (the gear icon in your dock or the Apple menu at the top left). Click Bluetooth in the left sidebar. Make sure Bluetooth is turned on — you'll see a toggle at the top of the window.
Turn on your mouse and look for a pairing button. This is usually on the bottom or side, and the instructions that came with the mouse will show you where. Hold the button down for three to five seconds until a light blinks or you hear a sound. Your mouse should appear in the Bluetooth list within a few seconds. Click it, then click Connect. That's it — your mouse is now paired and will reconnect automatically whenever you turn it on near your Mac.
If your mouse doesn't show up in the list after 30 seconds, restart the mouse by turning it off and back on, then try the pairing button again. If it still doesn't appear, restart your Mac and repeat the process. Once the mouse is paired, you won't need to do this again — it will remember your Mac and connect on its own the next time you turn it on.
Connecting a USB mouse
Plug the USB cable or receiver into any USB port on your Mac. If your Mac has only USB-C ports (like newer MacBook Pro or MacBook Air models), you'll need a USB-A to USB-C adapter, which you can buy for under $10. The mouse will work immediately — no pairing, no setup, no drivers needed.
If the mouse has a receiver (a small wireless dongle), plug that into the USB port instead of the cable. The receiver communicates with the mouse wirelessly, but the receiver itself stays plugged into your Mac at all times. Some USB mice come with both a cable and a receiver — check the instructions to see which one your model uses.
What to do if your mouse isn't working
For a Bluetooth mouse that won't connect, first check that Bluetooth is on in System Settings. Then restart the mouse by turning it off and back on. If the mouse still doesn't appear in the Bluetooth list, "forget" it and try pairing again: go to System Settings > Bluetooth, find the mouse in the list, click the X next to it, then repeat the pairing process from the beginning.
For a USB mouse that isn't responding, try a different USB port. If you're using an adapter, try a different adapter if you have one. Restart your Mac if the mouse still doesn't work. If the cable is damaged or the mouse is very old, it may not be compatible with your Mac — check the manufacturer's website to confirm.
Choosing between Bluetooth and USB
Bluetooth mice are wireless and don't take up a USB port, which matters if your Mac has only two USB ports. They also look cleaner on a desk. The trade-off is that they need charging (either batteries or a rechargeable battery), and they can occasionally disconnect if they're far from your Mac or if Bluetooth is turned off by accident.
USB mice never need charging and always work as long as they're plugged in. They take up a USB port, but that's rarely a problem if you have a USB hub. USB mice are also cheaper and have no pairing step, so they're the better choice if you want something that just works without thinking about it.
Using a trackpad instead of a mouse
If you don't want to buy a mouse, your Mac's built-in trackpad works perfectly fine for everyday tasks like browsing and email. You can also buy an Apple Magic Trackpad, which connects via Bluetooth the same way a Bluetooth mouse does. A trackpad takes up less desk space than a mouse and has no cable to manage.
Some people find a trackpad slower for certain tasks like gaming or detailed design work, where a mouse gives you more precision and speed. Try using your Mac's trackpad for a few days to see if it feels comfortable for your work — you might not need a mouse at all.
Frequently Asked Questions
Can I use a mouse from another computer brand on my Mac?
Yes. Most mice work with any computer — Windows mice, gaming mice, and basic office mice all work on Mac. The only exception is mice designed specifically for one operating system, which is rare. Check the box or the manufacturer's website if you're unsure.
Why does my Bluetooth mouse keep disconnecting?
This usually means the mouse is too far from your Mac (more than 30 feet away), the batteries are low, or Bluetooth got turned off. Check that Bluetooth is on in System Settings, replace the batteries if the mouse uses them, and move closer to your Mac. If it keeps disconnecting in the same spot, try moving your Mac or the mouse to a different location.
Do I need to install software or drivers for my mouse?
No. Mac recognizes almost all mice without any software. If your mouse came with a CD or download instructions, you can ignore them unless the mouse has special buttons that don't work without the software.
Can I use multiple mice on the same Mac?
Yes. You can pair as many Bluetooth mice as you want, and you can plug in multiple USB mice at the same time. Only one will be active at a time, but you can switch between them by using whichever one you pick up.
What if my Mac doesn't have Bluetooth?
All modern Macs have Bluetooth built in. If you have an older Mac without Bluetooth, use a USB mouse instead. You can also buy a USB Bluetooth adapter for around $15 to add Bluetooth to an older Mac.
