While Apple products have come in a wide variety of colors over the years, there also is a niche of Apple products devoid of all color – transparent prototypes. These were custom versions of products that were made with transparent/translucent cases. They were never sold to the public and were usually used to test air flow, which could be seen through the transparent cases. Others were simply made from clear plastic until a final case could be produced. Over the years a number of these internal prototypes have been leaked into the public sphere, although I’m sure the vast majority have never seen the light of day. I’ve collected a number of pictures of these prototypes below. Please email me any info or pictures you may have of other transparent Apple prototypes and I’ll add them to this post.
