Update:

Generations of MacBook Pro 2016 si 2017 (touch Bar) With display The 15-inch, are provided with Dedicated video card (graphic card), in addition to the "on board", Intel HD Graphics.
I have seen many users who have bought for the first time MacBook Pro or those who have upgraded from an older model, are a little bit puzzled about how does the dedicated video card work. Others are misled by the fact that in "About This Mac", The"Graphics"Does not appear as the video card is present on MacBook Pro.


In our case we have to deal with a MacBook Pro (15-inch, 2017), with video card integrated Intel HD Graphics 630 and a dedicated video card Radeon Pro 555.

If we go to the logo Apple → "About This Mac", on the "Overview" tab, we will find that only Intel HD Graphics appears. No sign of the dedicated Radeon card.

This is because at that time, the system does not use the graphics card. It does not need its operation.
If we open Adobe Photoshop (and we're set to use it graphics processor), the dedicated graphics card will automatically start working, and it will be present in "About This Mac".

So, on MacBook Pro with macOS High Sierra, graphics processor works only when it is needed.

How can we permanently activate the dedicated graphics processor / dedicated graphics card on macOS High Sierra

We do not know why anyone would want top graphics performance when they are not needed, but if you want to do this, you can permanently activate the graphics processor from: System Preferences → Energy Saver → uncheck:Automatic graphics switching".

Note, however, that once the dedicated graphics card is activated, battery life decreases considerably.

Automatic Graphics Switching it's a great feature because it helps you use your MacBook for as long as possible when it's not connected to a power source. Graphics card administration by macOS and the ability to turn it on and off only when needed saves a lot of battery power.

I am happy to share my experiences in the field of computers, mobile phones and operating systems, to develop web projects and to bring the most useful tutorials and advice. I like to "play" on the iPhone, MacBook Pro, iPad, AirPort Extreme and on operating systems macOS, iOS, Android and Windows.
