Doesn't this break using the remoting prefpane on older versions of OS X where
System Preferences is still a 32-bit app?

[Sergey Ulanov, 2016/01/04 18:12:24]

The host is compiled for 64-bit only. I assumed that System Preferences is
64-bit app by default on systems that support 64-bit. Is that not true?
