The basic steps to pair a wireless Mac mouse
To connect a wireless Mac mouse, turn on the mouse, go to System Settings on your Mac, select Bluetooth, and wait for the mouse to appear in the list. Click the mouse name, and your Mac will pair with it. The whole process takes about 30 seconds. After that first pairing, your mouse will reconnect automatically whenever it's in range and powered on.
The exact steps depend on which macOS version you're running, but the Bluetooth menu is always in System Settings. If you're using an older Mac with OS X 10.6 or earlier, you'll find Bluetooth in System Preferences instead — the location changed when Apple renamed the menu in later versions.
If your mouse doesn't appear in the Bluetooth list after 30 seconds, make sure the mouse is actually powered on. Check that the battery isn't dead by looking for a small LED light on the bottom of the mouse, or try moving the mouse closer to your Mac. Interference from other wireless devices can occasionally delay discovery, though this is rare with modern mice.
Key Takeaways
- Turn on your wireless mouse, open System Settings, select Bluetooth, and click the mouse name when it appears to complete pairing in under a minute.
- After the first pairing, your mouse reconnects automatically whenever it's powered on and within range of your Mac.
- If the mouse doesn't show up, check that it's powered on and the battery has charge, then try moving it closer to your Mac.
- Wired mice connect through a USB port and require no pairing — they work when ready once plugged in.
- Older Macs use System Preferences instead of System Settings, but the Bluetooth pairing process is otherwise identical.
Wired mice connect when ready with no pairing needed
If you have a wired USB mouse, there's no pairing step at all. Plug the mouse into any available USB port on your Mac, and it will work when ready. Your Mac recognizes it as an input device without any setup. This is the simplest connection method and works on every Mac with a USB port.
Wired mice don't require batteries and never lose connection, which makes them reliable for people who work in one place and don't move their computer around. The trade-off is that you have a cable running from your mouse to your Mac, which some people find inconvenient on a desk.
What to do if your mouse won't appear in Bluetooth
If you've turned on your mouse and waited 30 seconds but it still doesn't show up in the Bluetooth list, start by checking the battery. Most wireless mice have a small LED indicator on the bottom that lights up when powered on — if you don't see a light, the battery is likely dead. Replace the batteries and try again.
Next, make sure your Mac's Bluetooth is actually turned on. In System Settings, go to Bluetooth and look for the toggle switch at the top. If it says "Bluetooth: Off", click it to turn Bluetooth on. Some Macs also have a physical Bluetooth button or a keyboard shortcut to enable Bluetooth, though this is less common on newer models.
If the mouse still doesn't appear, try restarting your Mac. This clears any temporary Bluetooth glitches and often solves connection problems. After your Mac restarts, turn on the mouse again and check the Bluetooth menu. If the mouse appears this time, click it to pair.
For mice that still won't connect after a restart, check whether your Mac is too far from the mouse. Bluetooth typically works within 30 feet, but walls and metal objects can reduce that range. Move the mouse to within 10 feet of your Mac and try pairing again. If it works at close range, you may have a weak Bluetooth signal in your usual location — moving your Mac or mouse slightly can sometimes improve the connection.
Reconnecting a mouse that was previously paired
Once you've paired a mouse with your Mac, it stays in your Bluetooth memory. The next time you turn on that mouse, your Mac will automatically reconnect to it without any action from you. This happens in the background within a few seconds of powering on the mouse.
If your mouse doesn't reconnect automatically, check that Bluetooth is still on in System Settings. You can also manually reconnect by opening System Settings, selecting Bluetooth, finding your mouse in the list, and clicking "Connect". This is useful if your mouse disconnected because the battery ran low or because you were using it with a different device.
Switching a mouse between multiple Macs
A single wireless mouse can be paired with multiple Macs, but it can only connect to one at a time. To use the same mouse with a different Mac, turn off the mouse, turn it on near the new Mac, and it will connect to whichever Mac it's closest to.
If your mouse doesn't automatically connect to the second Mac, open System Settings on that Mac, go to Bluetooth, and click your mouse name to manually connect. Once connected, the mouse will prioritize that Mac until you move it near a different paired device or manually disconnect it.
Some people keep multiple mice — one for each Mac — to avoid switching back and forth. This is especially common in offices where someone works at a desktop and a laptop. Each mouse pairs with its own computer and stays there.
Troubleshooting a mouse that keeps disconnecting
If your mouse connects but then drops the connection repeatedly, the battery is usually the culprit. Wireless mice draw power constantly, and as the battery weakens, the connection becomes unreliable before it fails completely. Replace the batteries with fresh ones and the problem should stop.
Interference from other wireless devices can also cause disconnections, though this is uncommon with modern mice. If you have a lot of wireless devices near your Mac — routers, cordless phones, other Bluetooth devices — try moving the mouse closer to your Mac or moving other devices farther away. Microwaves can also interfere with Bluetooth, so if your Mac is near a kitchen, try moving it to a different room to test.
If disconnections continue after replacing the battery and ruling out interference, unpair the mouse and pair it again. In System Settings, go to Bluetooth, find your mouse, click the information icon next to it, and select "Remove". Then turn off the mouse, turn it back on, and pair it fresh. This resets the connection and often solves persistent problems.
Frequently Asked Questions
Do I need to do anything special to use a Mac mouse with a Mac?
No. Any wireless mouse that uses standard Bluetooth will work with any Mac that has Bluetooth. You don't need Apple-branded mice — third-party mice from Logitech, Microsoft, and other manufacturers pair the same way. Wired USB mice work on any Mac with a USB port, regardless of brand.
Can I use the same mouse with my Mac and my iPad?
Yes, if the mouse supports Bluetooth. Pair it with your Mac first, then pair it with your iPad separately. The mouse will connect to whichever device it's closest to, or you can manually switch by opening Bluetooth settings on each device. Some mice have a button to switch between paired devices, which makes switching faster.
What if my mouse is paired but won't respond to clicks?
Check the battery first — a dying battery can cause the mouse to connect but not respond properly. If the battery is fresh, try moving the mouse closer to your Mac. If that doesn't work, unpair and re-pair the mouse. If the mouse still doesn't respond after re-pairing, the mouse itself may be faulty and need replacement.
How do I know if my Mac has Bluetooth?
Almost every Mac made in the last 15 years has Bluetooth built in. To check, open System Settings, click Bluetooth, and see if there's an on/off toggle. If Bluetooth appears in System Settings, your Mac has it. Older Macs without Bluetooth can use a USB adapter, though this is rare.
Can I pair a mouse without using System Settings?
No. On macOS, System Settings is the only way to pair Bluetooth devices. Some mice come with software that adds extra features like custom buttons or sensitivity adjustment, but pairing always happens through System Settings first. The software is optional and only adds features after the mouse is already connected.
