What to Know
- A wireless Logitech mouse compatible with the Logitech Unifying Receiver can connect to any Unifying Receiver.
- You’ll need Logitech’s Unifying software to pair or un-pair a compatible wireless mouse.
- Mice not compatible with the Unifying Receiver only connect to the receiver they shipped with or Bluetooth.
This article includes instructions for syncing a Logitech wireless mouse with a different receiver and information about using Unifying- and Non-Unifying Receivers. There is also information on disconnecting a mouse from a wireless receiver.
How to Sync a Logitech Wireless Mouse With a Different Receiver
You can use any wireless Logitech mouse that supports the Unifying Receiver with any Unifying Receiver. A single Unifying Receiver can connect up to six wireless Logitech devices, including mice and keyboards.
Most wireless Logitech mice connect through a USB dongle called the Logitech Unifying Receiver. Your mouse will ship with a receiver, but you can sync the mouse to a different receiver if you lose it.
The next screen instructs you to turn your wireless mouse off and then back on. Do so and click Next.
The Logitech Unifying Receiver may not detect your wireless Logitech mouse during this step if it’s currently connected to your computer over Bluetooth. Disconnect it from Bluetooth to resolve this problem.
How Do I Unpair My Logitech Mouse From My Receiver?
You can use the Logitech Unifying software to unpair devices, as well. Here’s how to do it.
A screen will appear with a list of currently connected Unifying devices. Click the device you want to unpair and then tap Un-pair.
If you lost your Logitech wireless mouse’s Unifying USB receiver, you can buy a replacement receiver on the Logitech website for about 15. Alternatively, you can purchase a replacement on Amazon for around 10.
If your Logitech wireless mouse supports Bluetooth, you can connect it via Bluetooth instead of a receiver. To do this on a Windows 10 PC, go to Settings Devices Add Bluetooth. On your mouse, press the Connect button; the device should appear as an available Bluetooth device on your screen. Select it to complete the pairing process and use your mouse.
Possibly. First, update your Unifying Receiver if necessary. Then try uninstalling and reinstalling the software, then sync your mouse to the receiver. Check if you have the correct USB drivers installed on your PC. Search for the USB.inf and USB.PNF files. Uninstall any applications interfering with your receiver, such as software used to connect gaming controllers. If all else fails, replacing your wireless receiver is easy and relatively inexpensive.
No. For example, Logitech’s gaming mice don’t support the Unifying Receiver and instead use Logitech’s Lightspeed wireless feature. You can identify wireless Logitech mice compatible with Unifying by the square, sun-like icon printed on the mouse. This icon is also on the Unifying Receiver.
Wireless Logitech mice and keyboards that connect to a Unifying Receiver can’t connect to other receivers, including those made by Logitech. However, some wireless devices compatible with the Unifying Receiver also support Bluetooth.
How to Reset Bluetooth on Any Mac
Many users complain about hearing static or cracking sounds from their Bluetooth headphones or speakers. Or, Bluetooth peripherals like the wireless keyboard, mouse, trackpad, etc., keep constantly disconnecting from their Mac. If you’re facing similar connection issues and have tried the basic troubleshooting steps, the last option is to reset the Bluetooth module on your Mac. In this guide, we’ll help reset Bluetooth on your Mac, regardless of the macOS version.
Importance of Bluetooth on Mac
Before we get into the importance of Bluetooth, let me brief you about Bluetooth. In simple words, Bluetooth is a wireless communication technology that allows you to pair devices and share data wirelessly. It shares data through the 2.4GHz wireless Band. It is a cost effective technology solution that consumes very little power when transmitting data. The only drawback is that Bluetooth is meant for short distances and isn’t very effective for longer distances.
Today, there are various types of Bluetooth devices ranging from wireless headphones and speakers to keyboards, trackpads, and mice. These Bluetooth peripherals are convenient and look aesthetically better than their wired counterparts. Lastly, the primary purpose of Bluetooth technology on a Mac is to help you connect these wireless devices to your Mac.
Common Bluetooth Problems on Mac
Many users have connectivity issues with Bluetooth devices and ask questions like, “Why is my Bluetooth not available on Mac?”, “Why won’t my Bluetooth turn back on Mac?”, “Why is my Bluetooth not working?”, etc. The answers to these questions vary from device to device.
Firstly, the Bluetooth device might automatically disconnect from your Mac if it’s unused for a long period to save battery. If that’s the case, all you have to do is reconnect the Bluetooth device to your Mac.
Apart from this, you need to ensure that the Bluetooth device is compatible and has enough battery charge remaining to connect with your Mac. Then, you should keep the Bluetooth peripheral close to your Mac to avoid interference from other devices on the same 2.4GHz Band.
It can get frustrating if the Bluetooth devices are still not working or if your Airpods are still not showing on your iPhone, even after you’ve followed these instructions. The only option we are left with is to reset Bluetooth on Mac. Read along to learn how to reset Bluetooth on any Mac.
How To Reset Bluetooth on Any Mac
Before we begin, please ensure that you have a wired (USB) mouse and or keyboard available with you. It only applies to devices like the iMac, Mac mini, Mac Studio, etc., that do not come with an attached keyboard and trackpad. Because, when you reset Bluetooth, it disconnects from every wireless peripheral. While it will automatically reconnect after you restart your Mac, it’s always better to be safe than sorry.
Now that you’ve arranged a wired keyboard and mouse, you need to note that the steps to reset Bluetooth on Macs will depend on the macOS version. Regardless of which macOS version your Mac is on, we’ve got you covered. Read along to learn how to reset Bluetooth on Mac.
How To Reset Bluetooth on macOS Monterey and Above
Steps to reset Bluetooth on macOS Monterey and above
- Open the Terminal on your Mac.

Click OK to confirm your selection and reset Bluetooth on your Mac.
Delete Bluetooth Preferences File
Corrupted files in the operating system cause all kinds of nuisances in a computer. IIn our case, if the PLIST file that stores Mac’s Bluetooth preferences is corrupt, it might be why your Mac constantly disconnects from Bluetooth devices. Here’s how to delete the Bluetooth PLIST file and reset Bluetooth on your Mac.
Open the Finder on your Mac and click on the Go option at the top of the menu bar.
In the contextual menu, select the Go to Folder… option.
Now, type in the following path “/Library/Preferences/com.Apple. bluetooth.plist” and press return.
Control-click on the plist file and click the Move to Bin option.
Enter your Touch ID or Passcode to confirm your selection.
Restart your Mac and your device will automatically create the replacement Bluetooth PLIST file during startup.
If things go south, you can open the Trash and restore the deleted Bluetooth PLIST file.
No Bluetooth Disconnections
We hope and expect that all Bluetooth disconnection issues are resolved on your end. However, if you’re still facing errors, it might be time to contact the peripheral manufacturer. If it is an Apple accessory, get in touch with Apple Support and let them know about the same. If you have any other doubts, do let us know in the Комментарии и мнения владельцев and we’ll get back to you as soon as possible.
If you have enabled “Hey Siri” on your Mac, you can turn on Bluetooth by saying, “Hey Siri, turn on Bluetooth.” However, this only works if you’ve enabled Siri voice activation. Apart from this, there is no realistic method to enable Bluetooth on a Mac without a mouse or keyboard.
To reset Bluetooth on your Mac running on macOS Monterey, head to the Terminal type in “sudo pkill bluetoothd” press return enter your device’s password hit return again restart your Mac.
If you cannot see the Bluetooth icon on your Mac’s menu bar, head to System Settings Control Center Bluetooth Show in Menu Bar.

Logitech wireless USB dongles vulnerable to new hijacking flaws
A security researcher has publicly disclosed new vulnerabilities in the USB dongles (receivers) used by Logitech wireless keyboards, mice, and presentation clickers.
The vulnerabilities allow attackers to sniff on keyboard traffic, but also inject keystrokes (even into dongles not connected to a wireless keyboard) and take over the computer to which a dongle has been connected.
When encryption is used to protect the connection between the dongle and its paired device, the vulnerabilities also allow attackers to recover the encryption key.
Furthermore, if the USB dongle uses a key blacklist to prevent the paired device from injecting keystrokes, the vulnerabilities allow the bypassing of this security protection system.
Marcus Mengs, the researcher who discovered these vulnerabilities, said he notified Logitech about his findings, and the vendor plans to patch some of the reported issues, but not all.
Logitech Unifying dongles are impacted
According to Mengs, the vulnerabilities impact all Logitech USB dongles that use the company’s proprietary Unifying 2.4 GHz radio technology to communicate with wireless devices.
Unifying is one of Logitech’s standard dongle radio technology, and has been shipping with a wide array of Logitech wireless gear for a decade, since 2009. The dongles are often found with the company’s wireless keyboards, mice, presentation clickers, trackballs, and more.
Users can recognize if they’re using a Logitech USB dongle that’s vulnerable to these attacks because all Unifying dongles have an orange star printed on one of its sides, as portrayed in these Wikipedia images.
Below is a summary of Mengs’ discoveries and Logitech’s plan of action.
Mengs says that if an attacker can capture the pairing between a Unifying dongle and a Logitech wireless accessory, the attacker can recover the key used to encrypt traffic between the two components.
With the stolen key, the attacker is able to inject arbitrary keystrokes, as well as to eavesdrop and live decrypt keyboard input remotely, Mengs said.
Furthermore, in situations where the attacker has missed the dongle pairing operation, an attacker with physical access to the dongle could manually initiate a re-pairing of an already paired device to the receiver, in order to obtain the link-encryption key, by simply unplugging and re-plugging the dongle.
All Logitech Unifying USB dongles that support a keyboard input feature are affected. This includes both Logitech wireless keyboards using Unifying dongles, but also the dongles of MX Anywhere 2S mice, which can also accept keyboard input.
Demos are below, and Mengs says the attacks are invisible to users.
Logitech told Mengs that they don’t plan to issue a firmware patch for this vulnerability.
This response is the complete opposite to what Google did in a similar situation. When the search giant found out that attackers could pair a malicious device to a user’s computer because of a weak pairing process in the Bluetooth version of its Titan security key, Google issued a worldwide recall of all impacted Titan keys.
According to Mengs, this is a vulnerability through which an attacker can inject keystrokes into the encrypted communications stream between a USB dongle and a Logitech device, even without knowing the encryption key.
The researcher says the attacker needs physical access to a device to perform this attack. The concept is that an attacker presses between 12 and 20 keys and records the encrypted traffic, which he/she later analyzes and recovers the encryption key.
Physical access is required only once, so the attacker can collect enough cryptographic data from the radio traffic.
Once the data has been collected, arbitrary keystrokes could be injected, when and as often as the attacker likes, Mengs said.
Furthermore, when attacking certain type of wireless devices, such as presentation clickers, the attack is even more simple, as the attacker doesn’t need actual physical access, as he can infer when a next/previous button has been pressed, and classify the logged radio traffic accordingly.
Mengs says this vulnerability exists due to an incomplete fix for CVE-2016-10761, one of the infamous MouseJack vulnerabilities, and that Logitech has no plans on patching this new attack variation.

CVE-2019-13054 and CVE-2019-13055
CVE-2019-13054 and CVE-2019-13055 are technically the same vulnerability. The flaws require physical access to a Logitech Unifying dongle to successfully exploit.
According to Mengs, the dongles come with undocumented vendor commands and improper data protections that make it easy for an attacker to dump encryption keys stored on the dongles.
The entire attack takes one second to carry out, and once the hacker has the encryption keys, they can either sniff on the user’s keypresses or inject their own to perform malicious operations and take over computers.
Logitech told Mengs that a patch for this issue is scheduled for August 2019.
CVE-2019-13054 is used as an identifier for the vulnerability’s impact on Logitech R500 and Logitech SPOTLIGHT presentation clickers, while CVE-2019-13055 is used for all other Logitech devices using a Unifying dongle.
The reason why the Logitech presentation clickers were put in a separate category was because the attacker can also bypass key blacklists and inject key presses for keys between A and Z, which technically should not be supported on presentation clicker devices.

— Marcus Mengs (@mame82) June 24, 2019
On top of the four vulnerabilities he discovered over the course of the last months, Mengs also warned that many Logitech Unifying dongles are still vulnerable to the old MouseJack vulnerabilities disclosed back in 2016.
ZDNet reached out to Logitech a day before this article’s publication seeking additional information on these vulnerabilities and why the company did not want to address some flaws. The company did not return our inquiry.
Mengs’ full report is available here.
Updated on July 11 to add a link to Logitech’s security advisory for the vulnerabilities described in this article.
[Solved] Logitech Wireless Mouse Not Working
If your Logitech wireless mouse stops working, don’t worry. You can fix the problem with one of the below methods. These methods has helped many users resolve their Logitech wireless mouse (Logitech M325, M185, M510, M705, M570, etc.) not working issue.

4) After updating the driver, check to see if the problem is resolved.
If the problem continues to occur, go to Method 4.
Method 4: Change USB port
If the USB hub can’t provide the enough power to the mouse, the problem can occur. To fix Logitech wireless mouse not working issue, you can try to connect the unifying receiver to the computer via another USB port.
Unplug the receiver from the USB port and plug it to another USB port. Then check to see if the problem is resolved. Keep doing this until you’ve tried all USB ports on your computer.
If you’re using desktop, you can also try the USB ports at the back of the case.
If the problem cannot be resolved, go to Method 5.
Method 5: Test the receiver on another computer
Defective receiver can cause Logitech wireless mouse not to work. To find out if the receiver is the cause, you can test it on another computer.
Here’s how to test the receiver on another computer:
1) Open Device Manager on another computer ( refer to the steps in Method 2).
2) Expand the category Mice and other pointing devices.
3) Plug the receiver to one of the USB ports on the computer.
4) If the receiver can be recognized by the computer, you’ll see a new HID-compliant mouse show under the category Mice and other pointing devices. In this case, it means the receiver has no problems. The go to Method 6.
If you don’t see any changes under the category Mice and other pointing devices, it means the receiver can’t be recognized by the computer. It’s probably broken. You may need to replace it with a new receiver.
Method 6: Replace the batteries
The wireless mouse relies on AA alkaline batteries for power. If the batteries are having problems, your Logitech wireless mouse won’t have enough power to perform.
You can remove and insert the batteries again to see if the problem persists. If the problem persists, you can replace the batteries with new pair.
If new batteries don’t fix the problem, go to Method 7.
Method 7: Try using the mouse on a different surface
Electrical items and metal items may interfere with the signal of the mouse. Keep the mouse and the receiver away from the electrical items such as cordless or cellular telephones or other wireless mouse devices or receivers. Do not put the mouse or the receiver on metal surface or objects, especially long metal rails or cables.
If this method doesn’t work for you, go to Method 8.
Method 8: Try the mouse on a different computer
Try the mouse on a different computer. This will help determine if the mouse is dead.
If the mouse works on another computer, the device is working properly. If the device doesn’t work on another computer, you can consider replacing the mouse with a new one.
