Sometimes it is imperative to run Internet Explorer (IE) because a website depends on IE features. For example, some CourseWorks elements only work on IE. For Mac users, this is a problem because IE no longer exists for OS X. An alternative is to fire up Windows using Boot Camp or Parallels, but this is a heavy price to just run IE.

An alternative option is to load Internet Explorer for OS X (ies4osx). This free application allows you to run a number of IE versions side-by-side, which also facilitates testing for designers. Note that this application is only available for Intel-based Macs.
