M557 mouse is not working or 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

– Cell phones
– Garage door openers

Try to rule out these and other possible problem sources that might be affecting your mouse.

Mouse frequently stops working

M557 battery life and replacement****

Battery information
– Requires 2 AA alkaline batteries
– Expected battery life is up to 12 months

Checking battery status
You can check your mouse’s battery status using the Logitech SetPoint mouse and keyboard software. See answer 360023256814 for instructions.

Installing a new battery
When you install new batteries in your mouse, make sure they face the correct direction, as shown below.

Battery performance tips
Your mouse enters standby mode to conserve power when it is not in use. Here are some other ways you can help extend the battery life:
– Use only alkaline batteries. Non-alkaline batteries (such as NiMH or NiCd) operate at a lower voltage and may affect the battery life.
– Avoid using your mouse on dark or transparent surfaces, such as glass. These surfaces cause the optical sensor to use more power.
– Make sure replacement batteries are new and within the manufacturer’s expiration date.
– Don’t mix old and new batteries.

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.
