I am in SERIOUS need of disabling the Horizontal scrolling of my wireless MagicMouse! I recently switched to a fresh install of El Capitan 10.11.6 and tried the ever touted command line: defaults write com.apple.AppleMultitouchMouse MouseVerticalScroll -bool NO And it DOES NOT WORK! I have shut down and re-powered the mouse, rebooted, disconnected and reconnected bluetooth from the mouse and everything I can think of to try and get this to work with no avail! The command simply does not work. I CAN NOT use the system with this feature enabled AT ALL...it is imperative that I work in Libre Office Spreadsheets and this ******** insane feature completely disables the usability of the system! Can anyone HELP...PLEASE!!!!!!
