How to Fix Google Chrome Running Slow on Your Mac

Now that we've identified the potential culprits, let's explore actionable steps to speed up Chrome on your Mac.

1. Update Your Chome

If your Google Chrome is out of date, it may run slowly on your macOS. Updating it can ensure you benefit from the latest performance enhancements and bug fixes.

To update your Chrome:

  1. Click the Google Chrome menu and select About Google Chrome.
  2. Update your Chrome, and then relaunch the browser.

2. Close Unused Tabs

Each open tab consumes a portion of your memory space. The more tabs you have open, the greater the strain on Chrome's performance. By limiting the number of open tabs, you can free up Mac system resources, leading to a faster-running Chrome.

3. Remove Unwanted Extensions

Having too many extensions can also slow down your Chrome. It's recommended to remove unused and outdated extensions from your Chrome.

  1. Open Google Chrome.
  2. Click the three-dot menu next to your Google Chrome account, then select Extensions > Manage Extensions.
  3. Remove the extensions you no longer need.
