Apple has been equipping Mac computers with Intel processors for quite some time, which means that Turbo Boost technology is available to Apple computer users. However, the company does not give real control over this mode – it turns on and off in macOS automatically.

Perhaps some of this approach seems wrong. For example, if the fan noise of your computer seems too loud or the case heats up noticeably for no apparent reason. In this case, you can manually turn off the Turbo Boost for a while and check whether this will improve the situation, and at the same time extend the battery life by 25%.

What is Turbo Boost?

Speaking quite simply, Turbo Boost is an opportunity to increase the frequency of one or several actively used processor cores at the expense of the others that are not currently used. Unlike banal overclocking (for example, by changing the frequency multiplier in the BIOS), Turbo Boost is an intelligent technology.

First, the increase in frequency occurs depending on the current load of the computer and the nature of the tasks performed. For example, for fast single-threaded applications, it is important to speed up one core as much as possible (unpark cores). For multithreaded tasks, it is necessary to “force” several cores.

Secondly, in contrast to the same overclocking, Turbo Boost remembers the limitations of power, temperature and current in the composition of the calculated power – TDP (thermal design power). In other words, overclocking with Turbo Boost does not go beyond the normal operating conditions of the processor (all these indicators are constantly measured and analyzed), does not threaten to overheat and, therefore, does not require additional cooling.

The operating time of the system in Turbo Boost mode depends on the workload, operating conditions and platform design.

Turbo Boost Mac

To force Turbo Boost technology to turn on or off, a utility called Turbo Boost Switcher is used. But first you should check if your Mac supports the processor’s Turbo mode. To do this, check your computer model by clicking on the Apple logo in the menu bar and opening the “About this Mac” window.

Then go to support.apple.com and check the model you need for Turbo Boost support on the Mac specifications page.

Then go to support.apple.com and check the model you need for Turbo Boost support on the Mac specifications page. After making sure that your computer supports this technology, do the following:

  • Download Turbo Boost Switcher;
  • Extract the files from the downloaded archive and run Turbo Boost Switcher.
  • If you encounter an application error from an “unreliable developer”, go to System Preferences -> Security and Safety and in the Allow use of programs downloaded from section: select “Any source”;

  • After starting the application, you will see a lightning bolt icon in the status bar. When you click on the icon, a drop-down menu is activated, in which the processor temperature and fan speed are displayed;
  • To turn off Turbo Boost mode, simply select the appropriate option “Enable Turbo Boost”. If you need to enable this mode, then repeat this step, in this case choosing the option “Disable Turbo Boost”.

Conclusion

That’s all! In addition, the program can be configured to automatically disable Turbo Boost, when macOS itself considers it necessary. In this version, you do not have to configure everything manually every time.
