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.
