The fastest way: use Bluetooth pairing
Most Logitech keyboards connect to your Mac through Bluetooth, which means they talk to each other wirelessly without any cable. To connect one, you turn on the keyboard's Bluetooth mode, then tell your Mac to find it. The whole process takes about two minutes.
First, check whether your keyboard has a power switch and a Bluetooth button. Some Logitech keyboards have a small button labeled with a Bluetooth symbol (looks like a stylized "B" made of dots). Turn on the keyboard and press that button until a light on the keyboard starts blinking — that blinking means it is looking for a device to connect to.
On your Mac, open System Settings (or System Preferences on older Macs). Click Bluetooth in the left sidebar. Your Mac will start searching for nearby Bluetooth devices. When your Logitech keyboard appears in the list, click it, then click Connect. Your Mac may ask you to type a code on the keyboard to confirm — if so, type the numbers shown on your screen and press Enter.
Once connected, the keyboard light will stop blinking and stay on or turn off entirely. Your keyboard is now ready to use. You can close System Settings.
Key Takeaways
- Turn on your Logitech keyboard and press its Bluetooth button until the light blinks, then go to System Settings > Bluetooth on your Mac and select the keyboard from the list.
- If your Mac asks for a pairing code, type the numbers shown on your screen using the Logitech keyboard itself, then press Enter.
- Some Logitech keyboards use a USB receiver instead of Bluetooth — plug the small receiver into a Mac USB port and the keyboard will connect automatically without any pairing steps.
- If your keyboard does not appear in the Bluetooth list, restart both the keyboard and your Mac, then try again.
- Once connected, your keyboard will remember your Mac and reconnect automatically the next time you turn it on.
Using a USB receiver instead of Bluetooth
Some Logitech keyboards come with a small USB receiver — a tiny wireless adapter that plugs into your Mac's USB port. If your keyboard came with one, this is often simpler than Bluetooth because there is no pairing step at all.
Plug the receiver into any available USB port on your Mac. Your keyboard should start working when ready. You do not need to open System Settings or press any buttons. The receiver remembers your keyboard, so they will reconnect every time you use them together.
The receiver is usually stored in a small compartment on the bottom or back of the keyboard. If you have lost it, you can still use Bluetooth pairing instead — just follow the Bluetooth steps above.
What to do if your keyboard does not show up
If you turned on Bluetooth mode but your keyboard does not appear in the System Settings list, the most common fix is to restart both devices. Turn off the keyboard, wait five seconds, and turn it back on. Then restart your Mac by clicking the Apple menu, selecting Shut Down, waiting a few seconds, and turning it back on.
After your Mac restarts, go back to System Settings > Bluetooth and press the Bluetooth button on your keyboard again. It should appear in the list within 10 seconds. If it still does not show up, check that the keyboard has fresh batteries — a low battery can prevent Bluetooth from working.
If you have a USB receiver and the keyboard still does not work after plugging it in, try a different USB port on your Mac. Some ports on older Macs have less power than others. If you switch ports and the keyboard works, the original port may have a hardware problem.
Checking your keyboard is actually connected
Once your keyboard is paired, you can verify the connection is working by opening any document or text field and typing a few words. If the letters appear on your screen, the keyboard is connected and working.
You can also check the connection status in System Settings. Go to System Settings > Bluetooth, and look for your keyboard in the list. If it says "Connected" next to the keyboard name, the pairing is active. If it says "Not Connected," click the keyboard name and select Connect.
If your keyboard was working but suddenly stopped, the most common reason is that Bluetooth got turned off on your Mac. Click the Bluetooth icon in the menu bar at the top of your screen and make sure Bluetooth is turned on. If you do not see a Bluetooth icon, go back to System Settings > Bluetooth and toggle it on.
Switching your keyboard between devices
If you have multiple Macs or other devices, you can pair your Logitech keyboard to more than one. The keyboard will remember all of them. To switch between devices, turn the keyboard off, then turn it back on while holding the Bluetooth button. Some Logitech keyboards have multiple Bluetooth buttons (labeled 1, 2, 3) — each one connects to a different device you have already paired.
If your keyboard has multiple buttons, press the button for the device you want to use. The keyboard will disconnect from the old device and connect to the new one. This takes a few seconds, and you will see the light on the keyboard change or blink to show which device it is connected to.
If your keyboard only has one Bluetooth button, you will need to unpair it from one Mac before pairing it to another. Go to System Settings > Bluetooth on the first Mac, find your keyboard in the list, click the information icon next to it, and select Remove. Then pair the keyboard to your second Mac using the steps above.
Fixing common connection problems
If your keyboard connects but the keys do not work, or only some keys work, restart your Mac first. Many keyboard problems clear up after a restart. If the problem continues, go to System Settings > Bluetooth, remove the keyboard, restart your Mac again, and pair it fresh.
If your keyboard keeps disconnecting and reconnecting, move it closer to your Mac. Bluetooth works best within about 30 feet, but walls, metal objects, and other wireless devices (like microwaves or Wi-Fi routers) can interfere. If you are far from your Mac or there are obstacles between them, the connection may drop.
If you have a USB receiver keyboard and it is not working, try plugging it into a different USB port. If that does not help, the receiver may need new batteries, or the receiver itself may be damaged. Contact Logitech support with your keyboard model number — you can find it on the bottom of the keyboard or in the original box.
Frequently Asked Questions
Do I need to install software to use a Logitech keyboard on Mac?
No. Logitech keyboards work with macOS without any software. They connect through Bluetooth or USB and start working when ready. Logitech does make optional software called Logi Options+ that lets you customize keys and settings, but it is not required for the keyboard to function.
Can I use a Logitech keyboard made for Windows on a Mac?
Yes. Logitech keyboards work on both Windows and Mac. The connection process is the same, and all the keys will work. Some special keys (like Windows-specific shortcuts) may not do anything on Mac, but typing and basic functions work fine.
What if my Logitech keyboard has no Bluetooth button?
It probably uses a USB receiver instead. Look for a small wireless adapter that came with the keyboard, plug it into your Mac's USB port, and the keyboard will work when ready. If you cannot find the receiver, you can contact Logitech to order a replacement, or you can use a third-party Bluetooth adapter if your keyboard supports it.
Why does my keyboard work sometimes but not always?
This usually means the Bluetooth connection is weak or intermittent. Move your keyboard closer to your Mac, remove any obstacles between them, and check that your keyboard has fresh batteries. If the problem continues, remove the keyboard from System Settings > Bluetooth and pair it again from scratch.
Can I use my Logitech keyboard with my iPhone or iPad too?
Yes. Logitech keyboards can pair with iPhones and iPads the same way they pair with Macs. Go to Settings > Bluetooth on your iPhone or iPad, find the keyboard in the list, and tap it to connect. You can pair the same keyboard to multiple Apple devices, but it will only connect to one at a time.
