Starting from Mac OS X 10.6 just use -[NSString localizedStandardCompare:].

For earlier systems see Technical Q&A QA1159: Sorting Like the Finder

using custom selector in TableColumn Attribute special thanks to KennyTM 

// category on NSString for custom comparison
@interface NSString (FilesComparison)
- (NSComparisonResult)compareFiles:(NSString*)file;
@end
@implementation NSString (FilesComparison) 
- (NSComparisonResult)compareFiles:(NSString*)file {
    return [(NSString *)self compare:file options: NSCaseInsensitiveSearch|NSNumericSearch];
}
@end
