Turbo Boost is a performance enhancement technology found on high-end intel processors, including macOS. By default, macOS will enable and disable Turbo Boost automatically. However, by taking control of Turbo Boost, you can increase your Mac’s battery life by up to 25 percent. Here we show you how to disable and enable Turbo Boost manually on your Mac.
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.”
2. In the “Overview” tab, you’ll find the full name of your Mac. Copy this information to your clipboard.
3. Head over to Google and paste this information into your search bar. Add the phrase “technical specs” to the end and then hit “Google Search.”
4. Google will return a list of results. Click the result that takes you to the support.apple.com website. This is almost always the top result.
5. On the Apple Support website, check the “Processor” section. If your Mac supports Turbo Boost, it should be mentioned here.
If the technical specification doesn’t mention Turbo Boost, your Mac probably doesn’t support this feature.
Enabling or Disabling Turbo Boost
You can manually enable and disable Turbo Boost using the Turbo Boost Switcher application. Turbo Switcher is available as a free or paid application, but this tutorial uses the free version.
Once you’ve installed Turbo Boost Switcher, launch the application. Click on the icon that Turbo Boost added to your Mac’s menu bar automatically.
If Turbo Boost is already enabled, you’ll see a “Disable Turbo Boost” message. By contrast, if Turbo Boost is disabled, you’ll see an “Enable Turbo Boost” message. You can use these settings to manually toggle Turbo Boost on and off.
The first time you try to manually toggle 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 onscreen instructions to allow Turbo Boost Switcher to run normally.
Alternatively, you can unblock Turbo Boost Switcher manually by navigating to “Apple -> System Preferences … -> Security & Privacy.” Here you should see a message prompting you to unblock Turbo Boost Switcher.
What else can I do with Turbo Boost Switcher?
When manually manipulating Turbo Boost, you may want to monitor the impact these changes have on your Mac’s CPU temperature and battery.
You can view these metrics in the Turbo Boost Switcher drop-down and also analyze how these values change over time by selecting “Charts … ”
These charts display how your Mac’s CPU temperature and fan speeds fluctuate, depending on whether Turbo Boost is enabled or disabled.
By reviewing these charts, you can identify the Turbo Boost behavior that delivers the best results for your specific model of Mac and how you use your laptop.
If you upgrade to the Pro version, you’ll get access to some additional features, like disabling Turbo Boost automatically depending on fan speed, remaining battery time, and whether your Mac is connected to a power source.
As you can see, it is easy to manually enable or disable the Turbo boost feature in Mac. If you find that the battery drains too fast, you may want to force quit some apps or fix it when it freezes up. If your Mac has frozen up during an update specifically, we also have fixes for that.
