Question: Is this compatible with OS X 10.9.x or earlier? Or is it only for the latest pieces of shit that are 10.10&#x2F;10.11?<p><i>edit</i> thanks for the correction netheril96!<p>I&#x27;m curious about the state of compatibility because I&#x27;ve drawn a line in the sand -- and refuse to upgrade from 10.9 (since many things seem to be getting only worse and less stable in MAC OS land :).
