I was wondering what happened between 2014.03 and 2015.03 that means clicking an STL file generated by OpenSCAD in the Mac Finder now renders a white/transparent preview, whereas in the 2014 release things rendered visibly in grey.
It's not really a huge issue, but I was hoping the normals fix in 2015.03-1 would be it, but no. I haven't downloaded 2015.04 yet, but I don't expect it to help.
I can provide examples of pre/post 2015.03 STL files if needed.
I'm not sure if this is related, but I have noticed a difference with STL files generated with 2015.03.
When I pull the files into KeyShot for rendering they render as all black shapes. I'm not sure if the faces are flipped or what. But they can be fixed by repairing in NetFabb. This seems to happen with any/all STL files I export.
This seems to only have started since I upgraded to 2015.03

This sounds like https://github.com/openscad/openscad/issues/1317#issuecomment-94298621
It probably uses the supplied normals to calculate the shading.
@Torsten Thanks for the heads up, I did't realize there was a 2015.03-1. That fixed my issue.
@Nigel I'm pretty sure OS X doesn't generate STL previews on it's own. But it's possible you have installed Pleasant3D, or Cura previously that does include a QuickLook plugin. It's also possible you have this installed (http://www.thingiverse.com/thing:376361) but I imagine you would remember that because it takes a little work.

Ah ha, just downloaded and installed the latest 2015.03-1 (2015-04-21) and
all is good in the world again :)
The Mac finder is equivalent to the windows explorer and does a simple
preview built in. When you click on any file it recognises, it will generate
a little thumbnail.
