How to Disable Switching Graphics Card in a MacBook Pro

For owners of a top - end MacBook Pro including two video cards (GPU integrated and discrete), you will probably be aware that Mac OS and some applications will switch between the two graphics cards as needed. The idea behind this is for the applications to use the integrated GPU to try to conserve power and battery life and use the discrete GPU to try to maximize graphics performance at the expense of the battery and higher power consumption .

In general, changing the GPU is a great feature that should not be modified or adjusted in any way, but some advanced Mac users may wish to disable the automatic switching function of the graphics card on MacBook Pro models.

Note that when you disable GPU switching, you will always use the higher performance, discrete graphics card that uses more power. This can lead to better performance but surely impact the battery life of the MacBook Pro.

This will disable GPU switching and force the MacBook Pro to use the higher power discrete graphics card instead of the integrated GPU.
  • Go to the main menu and select "System Preferences" and then go to the "Power" control panel
  • Uncheck the box next to "Automatic change of graphics". Keep in mind that while this will positively affect the performance of the computer, it may negatively impact the battery life.
  • Close the system preferences panel as usual.

You can always return to the power preferences panel to re-enable the GPU switching function if you wish.
