Icns not working

[mifi]

Great project!
I tried generating the sample.svg from test using
icon-gen -i sample.svg -m icns -o ./icon-dist -r
The icns file itself shows the icon in Finder, and I can open it in preview and see the sizes there, however when I try to apply it to a folder (or electron app) the icon doesn't show up.
node v 6.7.0, mac os sierra.
I attached generated icon.

Icon generetor from SVG:

The icon we tried to preview it in my environment, but it seems normal.

My environment:

• MacBook Pro (Retina, 15-inch, Early 2013)
• macOS Sierra v10.12.1

Could you put a screenshot (Finder, Preview, or etc) so I want to see the broken state?

The icon I attached it working for you?
I have Mac OS Sierra 10.12 on MacBook Pro (Retina, 13-inch, Mid 2014)

Here's a video where I try to apply the Icon to a new folder in Finder (Get Info):

With my fix (#43) it's working and the icon of the folder changes.

Thank you.
I understood the summary problem.

I was seeing was a display on the Preview.app.
Check the Pull request because I can see the problem.
