The ergonomics (see pictures above)
The ergonomics of laptop screens is by definition absent or inappropriate here. As for the screen settings, they can only be made in brightness on the keyboard or in the System Preferences > Monitor. Very light but finally not at all embarrassing.
What is the Retina screen of Apple 13-inch MacBook Pro after calibration with the i1Display Pro worth?
So I calibrated a 15-inch Retina MacBook Pro 2017 with my i1Display Pro sensor. These are the P3 panel models.
 BEFORE CALIBRATING your Apple laptop - It is essential to first disable two display options on your MacBook Pro if you want to properly calibrate your Apple laptop. To do this, go to "System Preferences > Energy Saving" then "System Preferences > Monitors":
- Disable the energy saving option of lowering the brightness of your screen when you are not connected to the power grid,
- Disable the "Automatically adjust brightness" option.
 My recommendation! Once the calibration is done, you can still check these options if you want to manage your energy consumption as closely as possible, but at least you will have a correct ICC profile.
I choose the following screen settings:
I calibrated this screen - like all the screens I test - with the best current sensor (except the superlative and very expensive Discus) in an excellent price/quality ratio: the i1Display Pro + logiciel i1Profiler software (version 1.7.2) in order to be able to locate this new screen compared to the screens on the market. You will see that the figures are already barely believable if you remain convinced that Apple panels are only used to look pretty on a desk!
- Gamut: no choice! (DCI-P3 by default)
- Gamma: no choice! (2,2 by default)
- Contrast: no choice!
- Color temperature: no choice (6500 K by default)
And as target values in i1Profiler 1.7.2 software...
- Display technology: Choose white diodes,
- D65 or possibly a little less if you want a slightly warmer screen. (Note that at D55, the screen is really warm but not yellow like on cheap monitors),
- Luminance : 100 Cd/m2 or more depending on your main use (printing or web) and especially the brightness of your room,
- Contrast: Native,
- Gamma : 2,2 – standard curve,
- ICC norm: V2 (to avoid incompatibility problems with some image viewing software (images too dark) and obviously V4 if you know what you are doing).
- ADC Function: enabled
- Automatic room light control function: disabled.
And the result is?
First subjective impressions after this calibration...
Well, it's a real nice surprise, amazing even for a laptop. This is a very correct screen for any photographer who wants to start some photo retouching on the move or take pictures in connected mode. The combination: IPS panel, matt and Retina works really well, especially by displaying very subtle grayscales and without tone breaks!
Objective data : what does the final report say after calibration?
Before switching to Delta E, it is interesting to note the color temperature values achieved and the contrast of this Retina Apple panel.
 My opinion: Achieving a color temperature (CT) of 6469K for 6500K requested is a nice score on a laptop screen! Note - and enjoy! - the 811:1 contrast on a laptop as well. You will therefore not have any contrast problems with this screen even this one does not use state-of-the-art technology.
Now, let's move on to the famous Delta E after calibration according to the 2000 standard which I use for the calibration of all the monitors on this site:
My opinion! The average Delta E standard 2000 is 0.94 ! and there is hardly anything but a patch at 3.62 that makes this very good average go down quite a bit and as this color is neither a flesh hue nor the blue of the sky so it will only bother very few photographers. Not bad for a laptop screen even if the latest MacBook Pro 2018 do much better.
Now the harmonization tests in luminance and color temperature:
Frankly, getting such values on a laptop screen was a nice surprise in 2012. In 2018, this is still quite commonplace and the latest MacBook Pro 2017s are really doing better. We can still continue to work on this screen even if a 15-inch remains very small... but it is another debate that I am addressing on this page dedicated to the 4K...!
The disparities are more marked there and even if it is not necessarily visible to the naked eye, this screen clearly marks the step compared to a good photo retouching screen. There is indeed 250K of gap between the center and the upper right corner. That's a lot.
