How can you prevent a Kindle Fire from auto-mounting on a Mac when you plug it in to USB? I've got a Kindle Fire and I like to plug it in to my Mac to charge up (and also to do some development.)  It works fine but it is annoying to have to unmount it every time.

Is there any way to prevent it from auto-mounting when you plug it into USB?
Check Your Phone it should show some setting named 'Connect to PC'. Change the "Default connection type" to "Charge only".
