NSImage imageNamed: for Mac Mini returns a small icon instead of high resolution

Question

When using the method NSImage imageNamed:to get the icon for the current computer, if I work on a Mac Mini, I get a low-resolution image. If I run the same code from my MacBook, I get the high-resolution icon as I expected.

My code is as follows:

NSImage *image;
image = [NSImage imageNamed:@"NSComputer"];
[image setSize: NSMakeSize(512,512)];
NSData  * tiffData = [image TIFFRepresentation];
NSBitmapImageRep *bitmap = [NSBitmapImageRep imageRepWithData:tiffData];
data = [bitmap representationUsingType:NSPNGFileType properties:nil];
mime = @"image/png";

When I run this on my MacBook everything works fine and I get the 512x512 icon on my computer. When I run it on my Mac Mini, I get a 32x32 icon that has been enlarged to 512x512.

Any ideas on how I can get the high resolution version?
