How to Connect a Mouse to Your Mac

The fastest way to connect a wireless mouse

Most wireless mice connect to your Mac through Bluetooth, which means you turn on the mouse, hold down its pairing button for a few seconds, then select it from your Mac's Bluetooth menu. The whole process takes about one minute and requires no cables or dongles.

To start: turn on your mouse and locate its power switch or pairing button — this is usually on the bottom or side. Hold the pairing button (often labeled with a Bluetooth symbol) for three to five seconds until you see a light blink or flash. The mouse is now in pairing mode and broadcasting a signal.

On your Mac, click the Apple menu in the top-left corner, then select System Settings (or System Preferences on older Macs). Click Bluetooth in the left sidebar. Your mouse should appear in the list of available devices within a few seconds. Click it, then click Connect. Your Mac will confirm the connection and the mouse is ready to use.

Key Takeaways

Wireless Bluetooth mice pair through your Mac's Bluetooth menu and need no cables or adapters.
Wired USB mice plug directly into any USB port on your Mac and work immediately without any setup.
If your mouse does not appear in Bluetooth settings, restart the mouse's pairing mode and try again.
Magic Mouse and Magic Trackpad are Apple's own mice and trackpads that pair the same way as third-party Bluetooth mice.
If your mouse stops responding, forget it from Bluetooth settings and pair it again from scratch.

Connecting a wired USB mouse

A wired mouse plugs into any USB port on your Mac and works immediately — no pairing or setup required. Simply plug the USB cable into an available port on your Mac, and the cursor should respond to the mouse movement right away.

Wired mice are useful if you want to avoid charging batteries or if you prefer a direct connection. They work on any Mac with a USB port, including older models. If your Mac has only USB-C ports (like newer MacBook Pro or MacBook Air models), you will need a USB-A to USB-C adapter, which Apple sells separately or which you may already have for other devices.

Troubleshooting a mouse that will not connect

If your wireless mouse does not appear in the Bluetooth menu, start by checking that the mouse is powered on and has batteries installed. Look for a power indicator light on the mouse itself — if there is no light, the batteries may be dead or installed backwards. Replace the batteries and try pairing again.

If the mouse still does not appear, restart its pairing mode by holding the pairing button for five to ten seconds, then wait a few seconds and try again. Some mice require you to hold the button longer than you might expect. If your Mac still does not see the mouse, restart your Mac and repeat the pairing process from the beginning.

If a mouse you have already paired stops responding, open System Settings > Bluetooth, find the mouse in the list, click the information icon next to it, and select Forget This Device. Then pair it again as if it were new. This clears any corrupted connection data and usually solves the problem.

Connecting Apple's Magic Mouse or Magic Trackpad

Magic Mouse and Magic Trackpad are Apple's own input devices and pair exactly like any other Bluetooth mouse. Turn on the device, hold the power button on the bottom for a few seconds until the LED flashes, then go to System Settings > Bluetooth and select it from the list.

Magic Mouse and Magic Trackpad have rechargeable batteries built in, so you charge them with a USB-C cable rather than replacing batteries. They also support gestures — swiping, tapping, and pinching — that work across macOS. Once paired, these gestures are available in System Settings under Trackpad or Mouse, where you can adjust sensitivity and enable or disable specific gestures.

Using a mouse with an older Mac

Older Macs without Bluetooth (pre-2003 models) require a wired USB mouse. Plug the USB cable into any available USB port and the mouse will work immediately. These Macs do not support wireless mice unless you add a Bluetooth adapter, which is rarely worth the cost for machines this old.

Macs with Bluetooth but no USB-C (most models from 2003 to 2020) work with both wired USB mice and wireless Bluetooth mice. If you have a newer Bluetooth mouse but an older Mac, the pairing process is the same: turn on the mouse, hold the pairing button, and select it from Bluetooth settings.

Adjusting mouse settings after connection

Once your mouse is connected, you can adjust how it behaves in System Settings > Mouse (for a mouse) or Trackpad (for a trackpad). Here you can change the cursor speed, enable or disable secondary click (right-click), and adjust tracking speed.

For a standard mouse, the main settings are Tracking speed (how far the cursor moves when you move the mouse) and Secondary click (whether right-clicking works and which side of the mouse triggers it). For Magic Mouse or Magic Trackpad, you also get gesture options like Swipe between pages, Scroll direction, and Tap to click. Experiment with these settings to find what feels natural for your hand and work style.

Frequently Asked Questions

Do I need to install drivers for my mouse to work on Mac?

No. Most wireless and wired mice work immediately on Mac without any driver installation. Some gaming mice or specialty mice come with software that adds extra buttons or customization, but the basic mouse function works out of the box.

Can I use a Windows mouse on a Mac?

Yes. Any USB or Bluetooth mouse designed for Windows will work on a Mac. The only difference is that right-click may behave differently depending on your Mac settings, but you can adjust this in System Settings > Mouse.

Why does my mouse keep disconnecting?

Wireless mice disconnect when batteries are low, when they are too far from your Mac (usually beyond 30 feet), or when something is interfering with the Bluetooth signal. Try replacing the batteries first. If disconnections continue, move your Mac and mouse closer together and away from other wireless devices like routers or microwaves.

Can I connect multiple mice to one Mac?

Yes. You can pair as many Bluetooth mice as you want to your Mac, though only one will be active at a time. To switch between them, go to System Settings > Bluetooth and click the one you want to use. This is useful if you share a Mac or if you use different mice in different locations.

What if my mouse has a USB receiver instead of Bluetooth?

Plug the small USB receiver into any USB port on your Mac. The mouse will connect to that receiver automatically — no pairing needed. This type of connection is common on gaming mice and some older wireless mice. If your Mac has only USB-C ports, use a USB-A to USB-C adapter.
