can i download internt explorer on my mac

Not directly. Microsoft stopped making a Mac compatible version of Internet Explorer in 2006.

The current version of Internet Explorer (IE 11) is the last one Microsoft has said will be made. Starting with Windows 10, Microsoft has moved to their Edge Browser.

If you really need to run Internet Explorer or even Edge for any reason, you would need to install Windows either via Bootcamp or through virtualization software such as Parallels or Virtual Box.

Install Windows using Boot Camp for macOS - Apple Support

Parallels Desktop 13 for Mac - Windows on Mac

Oracle VM VirtualBox - Run Windows on Mac

No. It's not compatible with macOS.

If you want to use a different browser other than Safari, try Chrome or Firefox.

You're welcome.

You could also try going to Safari/Preferences/Advanced to enable the Develop menu. Then Safari/Develop/User Agent and select Internet Explorer.

Why do you think you want Internet Explorer on a Mac?
