System Extension Blocked message when installing Logitech Options or LCC

Starting with macOS High Sierra (10.13), Apple has a new policy that requires user approval for all KEXT (driver) loading. You may see a “System Extension Blocked” prompt (shown below) during the installation of Logitech Options or Logitech Control Center (LCC).

If you see this message, you’ll need to approve the loading of the KEXT manually so that your device drivers can be loaded and you can continue to use its functionality with our software. To allow KEXT loading, please open System Preferences and navigate to the Security & Privacy section. On the General tab, you should see a message and an Allow button, as shown below. In order to load the drivers, click Allow. You may need to reboot your system so the drivers are properly loaded and the functionality of your mouse is restored.

NOTE: As set by the system, the Allow button is only available for 30 minutes. If it has been longer than that since you installed LCC or Logitech Options, please restart your system to see the Allow button under the Security & Privacy section of System Preferences.

NOTE: If you don’t allow KEXT loading, all devices supported by LCC will not be detected by software. For Logitech Options, you need to perform this operation if you’re using following devices:
– T651 Rechargeable trackpad
– Solar Keyboard K760
– K811 Bluetooth keyboard
– T630/T631 Touch mouse
– Bluetooth Mouse M557/M558

Logitech Options issues when Secure Input is enabled

Ideally, Secure Input should only be enabled while the cursor is active in a sensitive information field, such as when you enter a password, and should be disabled right after you leave the password field. However, some applications may leave the Secure Input state enabled. In that case, you may experience the following issues with devices supported by Logitech Options:
– When the device is paired in Bluetooth mode, it’s either not detected by Logitech Options or none of the software-assigned features work (basic device functionality will continue to work, however).
– When the device is paired in Unifying mode, it’s not possible to perform keystroke assignments.

If you encounter these issues, check to see if Secure Input is enabled on your system. Do following:
1. Launch Terminal from /Applications/Utilities folder.
2. Type the following command in Terminal and press Enter:ioreg -l -d 1 -w 0 | grep SecureInput

– If the command returns back no information, then Secure Input is not enabled on the system.
– If the command returns back some information, then look for “kCGSSessionSecureInputPID”=xxxx. The number xxxx points to the Process ID (PID) of the application that has Secure Input enabled:
1. Launch Activity Monitor from /Applications/Utilities folder.
2. Search for PID which has secure input enabled.

Once you know which application has Secure Input enabled, close that application to resolve the issues with Logitech Options.

USB receiver storage in the M330 / M331 / B330 mouse

Your mouse was designed with a space where you can store the USB receiver. When you’re not using the mouse, you can store the receiver inside of it.

To locate the storage space for the receiver:
1. Flip the mouse over and slide the battery cover off.
2. Locate the small rectangular slot next to the battery compartment.
3. Slide the receiver into the slot. It will fit facing either way.
4. Replace the battery cover.
TIP: If you have an extra receiver from any Logitech device you aren’t currently using, this is a good place to store it.

M330 / M331 / B330 mouse not working or frequently stops working

– Mouse isn’t working
– Mouse frequently stops working

Mouse isn’t working

If your mouse isn’t working, the problem is likely a lost connection. The connection between the mouse and the computer can be lost for several reasons, such as:
1. Low battery power
2. Using your mouse on metal surfaces
3. Radio frequency (RF) interference from other wireless devices, such as:
– Wireless speakers
– Computer power supplies
– Monitors
– Cell phones
– Garage door openers

Before reconnecting your mouse
1. Fix or rule out the potential problem sources listed above.
2. Turn your computer on.
3. Insert fresh batteries in your mouse (see M330 / M331 / B330 mouse battery life and replacement for instructions).
4. Plug the receiver directly and securely into a working USB port on your computer.
5. Turn on your mouse using the power switch on the bottom.

The power indicator on the top of the mouse should be green.

Reconnecting your mouse
To reconnect your mouse to a Windows computer:
1. Download and run the Logitech Connection Utility. You can get the software from the Downloads page.
2. On the Logitech Connection Utility Welcome screen, click Next to continue.
3. Follow the instructions to turn your mouse off and then back on.
4. When your mouse is detected, you’ll see a confirmation message. Confirm that the mouse is working and then click Next.
5. Click Finish to exit the Connection Utility. Your mouse should now be connected.

6. If this solution doesn’t work after a couple of attempts, restart your computer and try the reconnection process again.

Mouse frequently stops working

– If your mouse frequently stops working and you keep having to reconnect it with the USB receiver, try these suggestions:
– Keep other electrical devices at least 8 inches (20 cm) away from the mouse and the host device.
– Move the mouse closer to the USB receiver.
– Move the receiver to a different USB port on your computer.

M330 / M331 / B330 mouse battery life and replacement

Mouse battery information
– Requires 1 AA alkaline battery
– Expected battery life is up to 24 months
Installing a new battery

When you install the battery for your mouse, make sure it faces the correct direction, as shown in the following image:

No optical light visible on the M330 / M331 / B330 mouse

Your mouse uses an infrared (IR) optical LED light that is invisible to the human eye.

If you’re not sure whether your mouse is powered on, check the On/Off switch located on the bottom.

When your mouse is:
ON — The switch is pushed over to the right and you see green next to it.
OFF — The switch is pushed over to the left and you see red next to it.

Unifying devices not detected after macOS 10.12.1 Sierra update

We are aware that after updating from macOS 10.12 Sierra to macOS Sierra 10.12.1, Logitech Options software does not detect supported Unifying devices on some systems.

To fix this issue, unplug the Unifying receiver and then plug it back into the USB port. If Logitech Options still doesn’t detect the device, you may also need to reboot your system.
