Apple Magic Mouse left and right clicker
Abilities using left and right mouse buttons? Not sure I get what you mean. As far as I know you can’t cast using a mouse click….
If you simply mean that you can’t right click then open System Preferences on your mac go to Mouse and enable Secondary Right Click.
You cannot set keybindings to your primary mouse buttons. Doesn’t matter which mouse you use.
If you have a mouse with additional buttons, those can be rebound, for example I have dodge bound to a thumb button.
