The Linux users’ guide to Mac OS X

“Fire up a Mac OS X machine, take a look at the desktop and,
aside from the layer of gloss, the first differences you’re likely
to notice coming from a Linux environment are the Dock and the menu
bar.

“Let’s deal with the latter first – you see, instead of
the OS having a menu bar for system tasks and each application
having its own individual bar within its window, in OS X there’s a
single menu bar at the top of the screen that alternates between
the two. The right-hand side of the bar contains the date,
information on your battery (where applicable), a wireless button,
and various other configurable options.

“Meanwhile, the left-hand side holds the application menu of
whichever program has your focus, or Finder if none has. As you
move between programs, this menu bar will change accordingly. The
Apple menu, accessed via the little Apple logo on the far left, has
a basic list of system operations and information.”
