Google ‘Systems Have Detected Unusual Traffic’ on iPhone & Mac

Key Takeaway: Users encountering the "Unusual Traffic" issue on Mac or iPhone while using Google search may find it frustrating, but common solutions include restarting the device, clearing browser history and cookies, and disabling VPN to resolve the problem and ensure smoother browsing experience.



Many users across the globe have run into the problem when they are trying to Google search for something on their Mac or iPhone. They frequently keep receiving a message, “Our systems have detected unusual traffic,” and they are asked to complete CAPTCHA. This wouldn’t be nerve-racking, except for those who have been affected; they usually receive messages frequently. In this troubleshooting guide, we’ll explain some of the possible solutions and how you can resolve them. 

How to fix “Unusual Traffic” Issue on Mac

Some users say that the error goes automatically on its own. Others encounter this problem occasionally. However, if you frequently keep receiving such issues, there are solutions you must try. But before, do understand what this error message means and its causes. 

What is the “Unusual Traffic” Error Message?

This error message can occur in any browser or device. You’ll encounter it when searching for any query in the Google Search Box and click search or using the address bar to find what you’re searching for. 

When you receive such an error message, your IP is displayed below, and there’s also a timestamp showing when it occurred. To continue browsing, you first need to solve the CAPTCHA and cross-verify that you’re not a robot.   

However, clearing a CAPTCHA isn’t an issue every now and then. But in most cases, error message still persists even if you resolve the CAPTCHA. It keeps reappearing when you try using Google search, eventually making browser more difficult to use and forcing to use an alternative browser.
