What OS X Gives You
These days, a key attraction of the Mac—at least as far as switchers are concerned—is security. Viruses and spyware are almost nonexistent on the Mac. (Even Microsoft Word macro viruses don’t run in OS X.) For many people, that’s a good enough reason to move to OS X right there.
Note
Apple no longer refers to its computer operating system as Mac OS X. Now it’s just “OS X,” without the “Mac.” Why? Apple says it’s to match up better with iOS, its operating system for the iPhone and iPad.
Along the same lines, Mail, Mac OS X’s built-in email program, deals surprisingly well with spam, the unsolicited junk email that’s become the scourge of the Internet.
If you ask average people why the Mac isn’t overrun by viruses and spyware, as Windows is, they’ll probably tell you, “Because the Mac’s market share is too small for the bad guys to write for.”
That may be true (although 65 million machines isn’t too shabby, as targets go). But there’s another reason, too: OS X is a very young operating system. It was created only in 2001, and with security in mind. (Contrast that with Windows, whose original versions were written before the Internet even existed.) OS X is simply designed better. Its built-in firewall makes it virtually impossible for hackers to break into your Mac, and the system insists on getting your permission before anything gets installed on your Mac. Nothing can get installed behind your back.
But freedom from gunkware and viruses is only one big-ticket item. ...
