OSX grants all processes realtime privileges whether they need them or
not.  For a DAW, that is probably fine.  For a server it's not so hot.
I suspect it leaves their system wide open to certain kinds of Denial
of Service attacks.

The realtime LSM for 2.6 kernels can do this if you want.  It also
offers some more secure options, such as granting realtime privileges
to all members of some group ID (like `audio').
