The basic connection process
Most Logitech mice connect to a Mac in one of two ways: through a wireless USB receiver (called a Unifying Receiver) or directly via Bluetooth. The method depends on which Logitech mouse you own. If your mouse came with a small USB dongle, you'll use the receiver method. If it has no dongle in the box, it connects via Bluetooth.
The receiver method is faster to set up and works immediately once you plug it in. Bluetooth connection requires a few extra steps in your Mac's settings but doesn't use a USB port. Both methods work equally well on modern Macs running macOS 10.15 or later.
Key Takeaways
- Logitech mice with a USB receiver plug into any Mac USB port and work without visiting System Settings.
- Bluetooth mice require you to open System Settings, select Bluetooth, and put the mouse in pairing mode before connecting.
- If your mouse doesn't respond after connecting, check that batteries are installed and the receiver is fully inserted into the USB port.
- Logitech's Unifying Receiver can connect up to six wireless devices to one Mac, so you can pair a keyboard and mouse to the same dongle.
Connecting with a USB receiver
If your Logitech mouse came with a small USB dongle, this is the simplest connection method. Locate the receiver — it's typically a small rectangular device about the size of a USB thumb drive. Insert it into an available USB port on your Mac. The port can be on the Mac itself or on a USB hub connected to your Mac.
Once the receiver is plugged in, your Mac should recognize it within a few seconds. Move the mouse around to test the connection. The cursor should respond immediately. You do not need to open System Settings or install any software for basic functionality. If the mouse has an on/off switch, make sure it's turned on.
If the mouse doesn't respond, remove the receiver and reinsert it firmly into the port. Check that the mouse has fresh batteries installed. Some Logitech mice have a small button on the bottom that you press to activate the connection — consult the manual that came with your mouse if the cursor still doesn't move.
Connecting via Bluetooth
Bluetooth mice have no USB receiver and pair directly to your Mac. First, turn on the mouse and locate the Bluetooth pairing button. This is usually a small button on the bottom or side of the mouse. Press and hold it for three to five seconds until a light on the mouse begins blinking — this means the mouse is in pairing mode and ready to connect.
On your Mac, open System Settings and click Bluetooth in the sidebar. Make sure Bluetooth is turned on — you'll see a toggle switch at the top of the window. Your mouse should appear in the list of available devices within a few seconds. Click the mouse name to connect it. Your Mac will pair with the mouse and remember it for future use.
Once paired, the mouse will connect automatically whenever it's turned on and within range of your Mac. If the mouse doesn't appear in the Bluetooth list, turn it off and on again, then press the pairing button once more. Some Logitech Bluetooth mice require you to hold the pairing button for longer — up to ten seconds — so check your mouse manual if it doesn't appear after the first attempt.
What to do if the mouse won't connect
The most common reason a Logitech mouse doesn't connect is dead or missing batteries. Open the battery compartment on the bottom of the mouse and check that batteries are installed and making contact with the metal springs inside. If batteries are present, try replacing them with fresh ones. Even batteries that power other devices may not have enough charge for a wireless mouse.
For USB receiver mice, try a different USB port on your Mac. Some ports may be disabled or reserved for specific devices. If you're using a USB hub, plug the receiver directly into your Mac instead. For Bluetooth mice, restart your Mac and try pairing again. Sometimes Bluetooth connections drop after a Mac wakes from sleep — turning the mouse off and on again usually fixes this.
If you've tried these steps and the mouse still doesn't work, check whether your Mac's Bluetooth is functioning by attempting to connect a different Bluetooth device, such as a phone or speaker. If other devices connect but your Logitech mouse doesn't, the mouse itself may be faulty. Contact Logitech support with your mouse model number and purchase date.
Using multiple Logitech devices with one receiver
The Logitech Unifying Receiver can connect up to six wireless devices to a single Mac. This means you can pair a Logitech keyboard and mouse to the same USB dongle without needing two separate receivers. The receiver handles all the devices automatically once they're paired.
To add a second device to an existing receiver, plug the receiver into your Mac as usual. Turn on the new device and press its pairing button. The receiver will detect it and add it to the connection. You do not need to unpair the first device or restart your Mac. If you want to pair more than six devices, you'll need a second receiver.
Adjusting mouse settings on your Mac
Once your Logitech mouse is connected, you can adjust how it behaves in System Settings. Open System Settings, click Mouse in the sidebar, and you'll find options for pointer speed, scrolling speed, and which button is primary. These settings apply to any mouse connected to your Mac, not just Logitech mice.
Some Logitech mice also come with their own software called Logitech Options or Logi Options+. If you want to customize buttons, adjust DPI (pointer sensitivity), or set up gestures, you can download this software from Logitech's website. The software is optional — your mouse will work without it, but the software unlocks additional features depending on your mouse model.
Frequently Asked Questions
Can I use a Logitech mouse on multiple Macs?
Yes. If your mouse uses a USB receiver, you can move the receiver between Macs and the mouse will work on each one. For Bluetooth mice, you'll need to pair the mouse to each Mac separately through Bluetooth settings. The mouse remembers all paired Macs and will connect to whichever one it's closest to.
Why does my Logitech mouse disconnect randomly?
Random disconnects usually mean low battery power. Replace the batteries with fresh ones and the problem should stop. If disconnects continue, move the mouse closer to the receiver or Mac — wireless interference from other devices can cause drops. For USB receiver mice, try plugging the receiver into a different USB port.
Do I need to install Logitech software to use my mouse?
No. Your Logitech mouse will work immediately after connecting without any software. Logitech Options or Logi Options+ software is only needed if you want to customize buttons, adjust DPI, or use advanced features. Basic pointing and clicking work out of the box.
What's the difference between a Unifying Receiver and a regular Logitech receiver?
A Unifying Receiver can connect up to six Logitech devices to one Mac. A regular receiver typically connects only one device. If your mouse came with a receiver, check the Logitech website with your mouse model number to see which type you have.
Can I use a Logitech mouse designed for Windows on a Mac?
Yes. Logitech mice work on both Windows and Mac computers. The connection method is the same — USB receiver or Bluetooth. The only difference is that some Logitech software features may not be available on Mac, but the mouse itself will function normally.
