IE is not available for Mac OS X.

Safari (comes with the OS) or Firefox (free download) are two good alternatives.
 
IE for Mac OS X 5.2.3

This is the last version I had (I have deleted it). I just ran it recently and it pretty much does not work on most of the sites that I visit. The advice to use Safari, Firefox is the best advice. But they might have a copy on softpedia (or you can Google around for it).
 
There's supposed to be a way to get IE to run on OSX using Wine Bottler, but I haven't been able to make it work. Instead, I have various Windows XP guest OS'es installed with VirtualBox for testing purposes.

I'm a big fan of Chrome these days too. Chrome finally has add-ons, and is incredibly fast -- faster than Firefox by a long shot. I still use Firefox for development, but Chrome is my daily browser.

BTW, I have an intense hatred of Internet Explorer. I recently did a big project where we HAD to support IE6. IE6 is awful, and IE7 and 8 aren't a whole lot better. I wish IE would just die a horrible, horrible death and go away forever.
