The basic steps for connecting a wireless or wired mouse

Most mice connect to an Apple computer in one of three ways: through a USB port with a cable, through a wireless receiver that plugs into a USB port, or through Bluetooth without any cable or receiver at all. The method depends on what type of mouse you have. Wired mice are the simplest — you plug them in and they work when ready. Wireless mice with a receiver require you to insert batteries and plug the receiver into a USB port. Bluetooth mice need you to turn on the mouse, then add it through your computer's settings.

Apple computers have used USB ports on the side or back for decades, and newer models with USB-C ports can accept USB mice through an adapter. Bluetooth is built into every modern Mac, so you do not need to buy anything extra for a Bluetooth mouse beyond the mouse itself and batteries.

Key Takeaways

  • Wired USB mice work when ready when you plug them into any USB port on your Mac.
  • Wireless mice with a receiver need batteries installed and the receiver plugged into a USB port before they will respond.
  • Bluetooth mice require you to turn them on, then pair them through System Settings under Bluetooth, which takes about one minute.
  • If your Mac has only USB-C ports, you will need a USB-A to USB-C adapter to use older wired or wireless receiver mice.

Connecting a wired USB mouse

A wired mouse has a cable with a USB connector on the end. Locate any USB port on your Mac — on older models these are on the sides or back, and on newer MacBook models they are on the sides. Plug the mouse cable directly into the port. The mouse will work within a few seconds without any setup.

If your Mac has only USB-C ports and your mouse has a traditional USB-A connector, you will need a USB-A to USB-C adapter. These are inexpensive and widely available. Plug the adapter into the USB-C port, then plug the mouse cable into the adapter.

Connecting a wireless mouse with a receiver

Wireless mice that use a small receiver (sometimes called a dongle) require two steps before they work. First, open the battery compartment on the bottom of the mouse and install the batteries that came with it, or new AA or AAA batteries depending on the model. Check the mouse documentation to see which type your model uses.

Second, locate the wireless receiver — it is usually a small rectangular device about the size of a USB thumb drive. Plug it into any available USB port on your Mac. The mouse should connect automatically within a few seconds. If it does not, check that the batteries are installed correctly and that the receiver is fully inserted into the port. Some mice have a small button on the bottom that you press to set up pairing; check the manual if the mouse does not respond after thirty seconds.

Connecting a Bluetooth mouse

Bluetooth mice do not need a receiver or cable. First, install batteries in the mouse if it uses them, or charge it if it has a built-in battery. Then turn on the mouse using the power switch on the bottom or side. Most Bluetooth mice have a button you hold for a few seconds to put them into pairing mode — the manual will show you where this button is and how long to hold it.

On your Mac, open System Settings by clicking the Apple menu in the top left corner, then selecting System Settings. Click Bluetooth in the left sidebar. Make sure Bluetooth is turned on — you will see a toggle switch at the top. Your mouse should appear in the list of available devices within a few seconds. Click on the mouse name to pair it. Once paired, the mouse will connect automatically whenever it is turned on and in range of your Mac.

Troubleshooting a mouse that will not connect

If a wired mouse does not work, try a different USB port on your Mac. Some ports may be damaged or not fully functional. If the mouse still does not work, the cable may be damaged — try the mouse on another computer to confirm.

If a wireless receiver mouse does not work, remove the batteries and reinsert them to reset the connection. Make sure the receiver is fully pushed into the USB port. If you have other wireless devices nearby, they may be causing interference — try moving the receiver to a different USB port or moving other wireless devices farther away. If the mouse still does not respond after thirty seconds, press the pairing button on the mouse again and wait for the connection light to stop blinking.

If a Bluetooth mouse will not pair, make sure Bluetooth is turned on in System Settings and that the mouse is in pairing mode. Try forgetting the mouse from your Mac and pairing it again. To do this, go to System Settings, click Bluetooth, find the mouse in the list, click the information icon next to it, and select Remove. Then turn the mouse off and on again, put it back into pairing mode, and pair it fresh.

When to use each type of mouse

Wired mice are the most reliable because they have no batteries to die and no wireless signal to drop. They are a good choice if you keep your Mac in one place and do not mind a cable on your desk. Wireless receiver mice offer freedom of movement without the setup complexity of Bluetooth — they work with older Macs that do not have Bluetooth, and they rarely have connection problems. Bluetooth mice are the cleanest option if you want no cables or receivers visible, and they work with any modern Mac.

Battery life matters most with wireless and Bluetooth mice. Receiver mice typically use AA or AAA batteries that last weeks or months depending on use. Bluetooth mice vary widely — some use replaceable batteries and last for months, while others have built-in batteries that need charging every few days. Check the product specifications before buying if battery life is important to you.

Frequently Asked Questions

Can I use a mouse made for Windows on my Mac?

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

What if my Mac does not have any USB ports?

Newer MacBook Air and MacBook Pro models have only USB-C ports. You will need a USB-A to USB-C adapter to use wired mice or wireless receiver mice. Bluetooth mice do not need any adapter and will work directly. USB-C hubs that provide multiple USB-A ports are also available if you need to connect several devices.

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

No. Standard mice work when ready on macOS without any software. Some gaming mice or mice with extra buttons come with software that lets you customize what those buttons do, but this is optional. The mouse will function without installing anything.

Can I connect multiple mice to one Mac?

Yes. You can connect as many mice as you have USB ports for, or pair multiple Bluetooth mice. Only one will be active at a time, but you can switch between them by unplugging one and plugging in another, or by turning one off and turning another on.
