How do i access internet explorer on macbook air

it was discontinued in 2003 and would not run on newer macs

ms is releasing their Edge (replacement for internet explorer) for mac one can download the betas already

if you truly need Internet explorer then your only option is to install windows in a virtual machine on the mac and run ie on the virtual machine

There are no versions of Internet Explorer for your Mac. There are several other web browsers available (Safari, FireFox).
