The MacBook Pro 2016 and 2017 ( Touch Panel ) 15-inch display come with a separate graphics card (Graphics Card), In addition to "On Board", Intel HD Graphics Card. 

I have seen that many users have bought their first MacBook Pro or those who have upgraded from the older model, I'm a little confused about how to make a dedicated graphics card . Others are accepted in error, and in " About this Mac ," " Graphics, " your graphics card does not appear as present on the MacBook Pro.

In our case we are dealing with the MacBook Pro (15-inch, 2017) , a graphics card Integrated graphics card Intel HD 630 and the discrete graphics card Radeon Pro 555 .

If you go to Apple's logo → "About this Mac ", the La tab ul "Overview" one obviously can not be seen than Intel HD Graphics. No tracks on Radeon.

This is caused at this point, the system uses graphics cards . It is not necessary for its operation. 
When you open Adobe Photoshop (and we have it set to use a 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, the graphics processor works only if it is needed.

How to activate a permanently dedicated graphics processor / dedicated graphics cards on MacOS high Sierra

I do not know why someone would like the highest graphics performance when you do not need them But if you want to do this, you can activate a standing graphics processor from: Uncheck System Preferences → Energy Saving →: " Automatic Graphic Switching ".

Note, however, that once a dedicated graphics card is activated, the battery usage time will drop significantly .
