I am not sure if this is due to a technical limitation on part of the application, or if it indeed is impossible to override the maximum mouse cursor speed.
Note that I am referring explicitly to the Mouse cursor speed – not the Trackpad cursor.
I am looking to increase the cursor speed of my Logitech Performance Mouse MX (without the use of Logitech Control Center!).
So the question is: How can the maximum mouse cursor speed be overridden (with a permanent setting) in macOS Sierra? Perhaps it could be done by a Terminal command or editing a plist file, but the solution could entail a third-party app.
