Persisting Mouse Settings
I'm using a external mouse/trackball on my MacBook Pro via a USB wireless connection. I need to change the Primary mouse button setting from left to right for left handed use. What I am finding is every time I reboot my computer this setting is reverted back to the default setting. How do I persist this setting so I don't have to constantly reset it?
MacBook Pro with Retina display, OS X El Capitan (10.11.2)
