MacOS Sierra
So, there&#x27;s no new features that anybody asked for, save the clipboard thing, which has unfortunate security implications, and there&#x27;s a ton of nonsense none of us will ever use, as the Mac platform gets increasingly complex (&quot;the computer for the rest of us&quot; is now anything but), moves away from Unix compatability, and doesn&#x27;t do anything useful with this additional complexity, but <i>does</i> cause emacs to crash.<p>I&#x27;d wait until they stabilize it a bit before upgrading. Or just don&#x27;t upgrade.
