I have own a MacBook Pro ever since late 2012, I think. I remember I purchased the model before the retina one came out. Now I have the late 2017 I think. And to this day, I am convinced, I mean, I know, that I barely know how to use it.

@Gaby you click the clicky thingy and press the dark rectangles. that’s all I am doing and it works most of the time? what else could one do?
