Use High Power Mode on your 16-inch MacBook Pro with M1 Max

High Power Mode maximizes performance in intensive sustained workloads like 8K color grading.

Your MacBook Pro has multiple energy modes you can switch between. By default, your Mac is set to Automatic mode to balance energy use and performance. Low Power Mode reduces energy use to increase battery life. On the 16-inch MacBook Pro with M1 Max, High Power Mode allows the fans to run at higher speeds. The additional cooling capacity may allow the system to deliver higher performance in very intensive workloads.

You can use High Power Mode to improve performance in graphics-intensive workflows such as color grading 8K ProRes 4444 and 8K DNxHR video. In video editing and 3D applications, you may experience smoother playback and faster exports when High Power Mode is on.

When High Power Mode is on, the fan may run at a higher speed and you may hear additional fan noise. High Power Mode can be used whether your Mac is connected to power or not.

Turn on High Power Mode

  1. Choose Apple menu  > System Preferences, then click Battery.
  2. Click Battery or Power Adapter in the sidebar, then choose High Power Mode from the Energy Mode pop-up menu.

You can set different energy modes for when your Mac is on battery or connected to the power adapter depending on your preferences. For example, you could choose to turn on High Power Mode only when your Mac is connected to the power adapter.
