The 2019 Apple MacBook Air is a slight improvement from the 2018 model. With very few changes both models are near identical in performance and design. The new feature for the 2019 MacBook Air is the inclusion of True Tone adaptive screen technology. This feature automatically adjusts the temperature of the colours in the display for a more comfortable viewing experience. The MacBook also shares some features of the previous model such as the Touch ID sensor, the 8th generation dual core processor and a long battery life.
