macOS sierra scrollbar issue After upgrading to macOS sierra I've noticed that scrollbars are appearing always, even if I go to settings and then select appear when scrolling it still shows them and after quitting and going back to settings it reverts back to appear always. Is there any ways to solve this issue myself?
Go to finder and press command+shift+G on your keyboard and the dialogue box that appears paste in - this path in it 

/Users/your
username/Library/Preferences/com.apple.AppleMultitouchMouse.plist and delete this plist file com.apple.AppleMultitouchMouse.plist then go to system preferences and click on general and instead of selecting appear when scrolling select automatically based on mouse or trackpad
