When I open myicon.tif in Preview, the icon is on top of a black background. I thought it might be the alpha channel, but then Preview should be able to deal with transparency... What is it that goes wrong?

Just a guess: Have you tried doing an NSRectFill() with clearColor (transparentColor? whatever...) before drawing? It might just be that the image starts out opaque and when you draw it just composites on that?

Otherwise, is there any reason why you can't use NSWorkspace's iconForFile: ?
