After downloading the archive you’ll see one PSD file and one DOC file with the instructions of how to use PSD fiile. There’s two groups of layers in PSD file with Ipad and MacBook and to use one of them you need to switch on the neccesary group and switch off the one that you don’t need.

This mock up contains a number of elements that you can also switch on or off: 1) light effects from Ipad and MacBook 2) needles from Ipad and MacBook 3) shadows and highlights from Ipad and MacBook

Forest, squirrel, and stone are merged to one layer. And what is the most important – you can change the desctop image in Ipad and MacBook to whatever you want just by changing the smart object – it’s very easy!
