What is Google Chrome Helper?

First things first: what is Google Chrome Helper, and what on earth does it do?  


We all know about Google Chrome. It’s a popular web browser used by billions of people globally. So popular, in fact, that it’s the leading browser, claiming more than 75.6% of the market share as of February 2023—according to StatCounter.


There are many reasons why Google Chrome is so popular:

  • It’s a user-friendly browser that makes it pretty easy to find what you’re looking for
  • It’s free, which makes it accessible to more people
  • It’s equipped with all the features that come standard with any browser.

These features include third-party extensions, which use third-party content, so they don’t always work seamlessly with the browser.  


Google Chrome Helper closes that gap and facilitates a smooth experience between the two parties. This allows you to use Chrome plugins without any issues. But it’s probably increasing GPU usage and taking up memory or RAM on your Mac, so you may need to stop it.

Can a user disable Google Chrome Helper?

You can quickly check Task Manager on Mac (hit Command + Alt + Esc) to see what Apps and programs are running in the background. If Google Chrome Helper is using too much CPU on your Mac and causing Chrome to get frozen, the obvious solution is to turn it off… But can you do that?


Before we get to that, let’s look into the reasons Google Chrome Helper causes issues.

  • The processes linked to Google Chrome are running simultaneously
  • The Chrome extensions you downloaded have some form of spyware or malware installed (Learn how to check your Mac for malware)
  • There’s a problematic extension in Chrome
  • Google Chrome uses plugins that work with Flash content.

We’re going to show you exactly how to quit Google Chrome Helper on your Mac. However, it’s important to note the impact this may have.  


While disabling Google Chrome Helper may fix the issue of over-utilization, it’ll render third-party plugins inoperable in Chrome. As a result, tools like video players won’t work as they should.  

How to disable Google Chrome Helper on Mac

If you’ve had enough of Google Chrome Helper slowing down your Mac and troubleshooting hasn’t helped, you can remove it. Who wants to deal with a lagging computer, anyway?


Follow the steps below to remove Google Chrome Helper on Mac on older Chrome versions:


1. Open Chrome, click the three-dot menu in the top-right corner and follow the sequence: Settings > Privacy and Security > Site Settings > Additional Permissions

On newer Chrome versions, simply revert Chrome to default settings. Here’s how:

  1. In the Chrome browser, click on the three-dot menu > Settings > Reset settings > Restore settings to their original defaults
  2. Click the Reset settings button in the pop-up window.
