Clipping a raster layer with a shapefile on mac

I am trying to clip a raster layer using the raster clipper function. However, for some reason this is not working for me and I haven't been able to find the answer anywhere.

I choose my raster layer as the input file, my shapefile as the mask layer and creates an output file, but after pressing OK nothing happens.

I am using QGIS 2.6.0 and following the steps presented at: http://ift.tt/1C5thin

Does anybody have an idea of what I might be doing wrong?

Thanks in advance.
