Why is the buffer slider missing in the Rane audio driver panel in Mac OSX?

Rane removed the buffer slider from the control panel to simplify the user experience and to be consistent with Core Audio implementation.

The audio buffer size for Rane hardware is now controlled in the Audio panel of the Serato DJ Setup screen.

This is for Mac OSX only, on Windows the slider is greyed out in the setup screen and you can ONLY adjust it from the Windows control panel.
