@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.
@c ==================================================================
followed by an IP header.
This mode should support both IPv4 and IPv6 packets.
+@cindex utun
+@item utun (OS X)
+Set type to utun.
+This is only supported on OS X version 10.6.8 and higher, but doesn't require the tuntaposx module.
+This mode should support both IPv4 and IPv6 packets.
+
@item tap (BSD and Linux)
Set type to tap.
Tinc will expect packets read from the virtual network device
