Exploring OS X: Mac Server
Those interested in using OS X as a server can do so by purchasing the server upgrade
via the Mac App Store. As well as adding server applications of various kinds,
including a calendar and a wiki, the server upgrade adds several GUI user manage-
ment and system monitoring tools to a standard OS X installation. It also adds support
for the Xsan cluster filesystem. However, key OS X tools like Time Machine are also
included, which can make the ordinarily complex procedure of server backup as easy
as backing up a desktop computer.
A key feature of OS X Server compared to other server operating systems is that the
purchase price of OS X Server allows an unlimited number of clients. This indicates
the smaller-business orientation of OS X Server, a market that Apple claims includes
“small studios, retail shops, even home-based businesses” and “people who never
thought they could run a server.”
Apple ceased production of dedicated Mac server hardware in 2010 and currently
recommends either the Mac Pro or high-end Mac Mini desktop systems be used for
those who require server hardware.

Hide Files
There are two ways of making files invisible on your Mac. Neither is bulletproof
from a security standpoint, and anybody with know-how would be able to
uncover them in seconds. But for quietly hiding a file or two for a short period,
they're worth considering. If you need to protect files from prying eyes, take
Hiding Files via Unix
Your Mac's operating system, OS X, is actually a version of Unix. In Unix,
you can make a file invisible by adding a period (.) in front of its filename,
and this works on Macs too. This means the file won't show up in Finder
windows, in file open dialog boxes, or on the desktop. Those browsing at the
command line won't be able to see it unless they specifically request to view
hidden files (that is,
LS-A
).
For example, typing a filename of
.DOCUMENT.DOCX
when you're saving a file will
render it invisible. You'll probably be warned that putting a period in front of
