I've created an alias to a file on my Yosemite desktop. I want to change the icon, so I've found a PNG file I want to use. When I open the Get Info window for the alias, click the little icon and copy/paste or drag the PNG file there, all I get for an icon is the generic PNG one. I've tried opening the PNG in Preview and doing Cmd + A then Cmd + C to copy it that way, same result. I've also tried with a JPG file and an ICNS file, same result (generic icon for each) I've tried Relaunching Finder and doing killall Finder, didn't fix it, Late-2013 rMBP with Yosemite 10.10.2.
