On my machine, the constant is kComputerIcon, not kComputer, and yes, it 
evaluates to Root. RubyCocoa isn't going to recognize the Ruby constant 
KComptuerIcon or anything like it, though, because at least on my 
machine all that stuff is pure C stuff (not Objective-C) which isn't 
accounted for yet by custom bridge-support files. You can try fooling 
around with bridge-support, but I'd just skip kComputerIcon entirely and 
use what it evaluates to, the string 'root'.

That out of the way, according this source: [1], the correct line in 
Objective-C would be
   SImage* macIcon = [[NSWorkspace sharedWorkspace] iconForFileType: 
NSFileTypeForHFSTypeCode(kComputerIcon)];

To me, that translates as: 
OSX::NSWorkspace.sharedWorkspace.iconForFileType(OSX::NSFileTypeForHFSTypeCode('root'))

so, try that out.
