Safari for Mac supports the following user agents: VPN Deals: Lifetime license for $16, monthly plans at $1 & more And while Internet Explorer was removed from the default list of user agents in macOS Catalina, you can still add it as on by changing the user agent string manually. It can event tell a website that you're running Windows. Changing the user agent tells websites that you're using a browser other than the version of Safari that you're using on your Mac. Safari allows you to masquerade as the user of other browsers and Windows through a tool in its Develop menu: changing the user agent. Luckily, Safari on Mac has the answer for you.

Whether you develop for the web and need to see how your site or web app displays itself in multiple browsers, or you just want to visit a site that requires a particular browser that you don't want to use, you may eventually need to use a browser other than Safari.
