New icons come up as default file icon in El Capitan I'm not able to properly set icons, I've tried with *.icns and *.pngs.

I'm on a El Capitan, MacBook Pro (Retina, 13-inch, Early 2015)

Does this seem familiar to anyone?



EDIT: I should mention I don't want to disable any security
Try opening the icon in Safari then dragging it from there.
