If you’re like most people, you use Safari on your Mac to browse the web. But what if you want to use another browser, like Firefox or Chrome? You can change Safari’s user agent, but it’s not always easy. In this article, we’ll show you how to do it. First, open Safari and click on the menu bar at the top of the screen. Then click on “Preferences.” In the “Preferences” window, click on the “Advanced” tab. Under “General,” click on the “User Agent” button. Now, in the “User Agent” window, scroll down until you see a list of browsers. Click on the name of the browser that you want to use (for example, Firefox). Next, in the “User Agent” window, under “Safari,” type in a different user agent (for example: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.87 Safari/537.36). ..


You’ve probably been annoyed at one time or another when visiting a website that requires a specific browser. Luckily, you can fool a website into thinking you’re using a different browser and you can do this with most, including Safari.

User agent “spoofing” is not a new thing. It was sometimes necessary when there was a so-called browser war. Website designers would often design pages to render and deliver different content depending on the user’s browser. The solution to this was often to send a false “user agent string,” which would fool the web server into delivering you the preferred content.

Today, users are less likely to have a problem since websites and browsers are better at adhering to web standards. That’s not to say you won’t still encounter one every now and then.

If you use Apple OS X’s Safari, here’s how you change the user agent, and even create custom ones as well.

What is a User Agent Anyway?

When Safari visits a website, it will send a string of text such as this:

This tells the web server that this particular user is running Safari 8 on a Mac running OS X 10.10.2.

It will obviously be different per the operating system and web browser. A computer running Windows 7 and Internet Explorer 10 would appear as such:

The list of user agent strings is quite extensive because there are so many browsers on different operating systems. By the way, it’s possible to see what information your browser reveals about you, which includes your screen resolution, IP address, and more.

Changing Your User Agent on Safari

We’ve discussed the ways you can change the user agent on Google Chrome, Internet Explorer, and Firefox. Let’s discuss now how to change it on Apple OS X’s Safari.

First, open Safari’s preferences from the “Safari” menu or with “Command + ,”.

With the preferences open, click on the “Advanced” tab. At the very bottom, you want to check the box next to “Show Develop menu in the menu bar” and then exit out of the preferences.

Now Safari will have a new menu devoted solely to development tools.

The “User Agent” menu is at the top. There’s already quite a few options available including preceding versions of Safari on OS X and iOS, Chrome on Mac and Windows, as well as an “Other…” option.

The “Other…” option allows you to specify a user agent other than those listed, such as if you’re curious to see how Google Chrome on an iPad running iOS 8.2 renders, you’d use the appropriate string.

When you open the “Other…” option from the User Agent menu then, you’d simply type of copy the user agent string for the browser you want to test.

Afterwards, the new user agent will appear in the User Agent menu. Note, however, you can only have one “other” user agent at a time.

As we suggested in the introduction, it’s unusual to have to change your user agent because most browsers are fairly good now at adhering to standards, and most websites are browser agnostic (though some browsers work better on some sites than others).

On a related note, if you’re curious to see how your browser does with regard to web standards, you can always try the Acid Tests developed by the Web Standards Project.
