To do this, you'll need VirtualBox, the free-to-download and free-to-use virtualization software which allows you to run Windows and other “guest” operating systems on a Mac “host.” Now you can run the latest version of Internet Explorer on Macs using virtualization. For those of you requiring Internet Explorer to run ActiveX Controls on the Mac, this is the perfect solution. The last official Internet Explorer for Mac is no longer functional since the release of OS X 10.7 (Lion) and is discontinued since 2005, but we have a fix!
