Just purchased Spine and working on getting my first character imported into Unity for a game jam. I get to the step where you drag the png, json.txt and atlas.txt over, but then the skeleton is not created like in the GIF in the instructions. Followed a couple other tutorials with the same result. Cant find any other forums where this is happening, could really use some help. I am working on a Macbook, not sure if that matters. Unity Version 19.1.
