The Simplified BSD license used by FreeBSD is essentially identical to the MIT License, as it contains neither an advertising clause, nor a prohibition on promotional use of the copyright holder's name.

Neither Mac OS X nor FreeBSD maintain the microkernel structure pioneered in Mach, although Mac OS X continues to offer microkernel inter-process communication and control primitives for use directly by applications.

To determine what color to use for a file, GNU < tt > ls </ tt > checks the Unix file type, the file permissions, and the file extension, while FreeBSD < tt > ls </ tt > checks only the Unix file type and file permissions.

Based on the FreeBSD Documentation License, the BSD Documentation License was created to contain terms more generic to most projects as well as reintroducing the 3rd clause that restricts the use of documentation for endorsement purposes ( as shown in the New BSD License ).

Most operating systems ( including Solaris, Mac OS X and FreeBSD ) use a hybrid approach called " adaptive mutex ".

Most current Unix-like systems, and Microsoft Windows, support loadable kernel modules, although they might use a different name for them, such as kernel loadable module ( kld ) in FreeBSD and kernel extension ( kext ) in OS X.
