@subsection Configuration of Darwin (MacOS/X) kernels
Tinc on Darwin relies on a tunnel driver for its data acquisition from the kernel.
Tinc supports either the driver from @uref{http://tuntaposx.sourceforge.net/},
OS X version 10.6.8 and later have a built-in tun driver called "utun".
Tinc also supports the driver from @uref{http://tuntaposx.sourceforge.net/},
which supports both tun and tap style devices,
and also the driver from from @uref{http://chrisp.de/en/projects/tunnel.html}.
The former driver is recommended.
The tunnel driver must be loaded before starting tinc with the following command:
@example
kmodload tunnel
@end example
By default, tinc expects the tuntaposx driver to be installed.
To use the utun driver, set add @code{Device = utunX} to @file{tinc.conf},
where X is the desired number for the utun interface.
You can also omit the number, in which case the first free number will be chosen.
