How to Enable or Disable Turbo Boost on Your Mac

How To Enable Or Disable Turbo Boost On Your Mac

Turbo Boost is a feature built into many Macs using Intel processors. You may not even know that it exists, but behind the scenes, macOS is enabling and disabling Turbo Boost. When you need more performance, macOS enables Turbo Boost. When the computer is idling or doing something similarly low-effort, macOS turns off Turbo Boost. This works perfectly most of the time, but it doesn’t always. If your computer is getting older and you want to make your battery last longer, you can manually control Turbo Boost to use less energy.

Finding Out If Your Mac Has the Turbo Boost Feature

Before you move forward, you should verify that your Mac actually supports the Turbo Boost feature:

  1. Select the Apple logo in your Mac’s menu bar and click “About This Mac.”
Opening About This Mac2
  1. Copy the full model name of your Mac by selecting it and pressing + C.

  1. Open a browser tab, press + V to paste this information into your search bar, and hit Enter. In the search results, click the link to the support.apple.com website, which is almost always the top result.

If the technical specifications don’t mention Turbo Boost, your Mac probably doesn’t support this feature. If you have a newer Mac with an M1-based chip, it doesn’t support Turbo Boost.

Note: the first time you try manually toggling Turbo Boost, macOS will ask for your admin username and password.

macOS may also block Turbo Boost Switcher from running. If you encounter a “Security & Privacy” message, follow the on-screen instructions to allow Turbo Boost Switcher to run normally.

Alternatively, you can unblock Turbo Boost Switcher manually by navigating to the “Security & Privacy” section. You should see a message prompting you to unblock Turbo Boost Switcher.

How to Check Temperature and CPU Load with Turbo Boost Switcher on Mac

When manually manipulating Turbo Boost, you should monitor its impact on your Mac’s CPU temperature and battery life.

  1. Click on the “Turbo Boost” icon in the top-right corner, and select “Charts.”

  1. View these metrics and analyze how these values change over time.

These charts display how your Mac’s CPU temperature and fan speeds fluctuate, depending on whether Turbo Boost is enabled or disabled.

By reviewing that information, you can identify the Turbo Boost behavior that delivers the best results for your specific model of Mac and how you use your laptop.

Finally, upgrading to the Pro version of Turbo Boost Switcher gives you access to additional features, like disabling Turbo Boost automatically, depending on fan speed, remaining battery time, and whether your Mac is connected to a power source.
