But it's not how OS X works. Quoting the NSURL Additions documentation
https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ApplicationKit/Classes/NSURL_AppKitAdditions/Reference/Reference.html%23//apple_ref/doc/uid/TP40004147 it says "You must declare an NSURLPboardType data type for pasteboard before invoking this method; otherwise it returns without doing anything." So, the correct fix is adding
[pb declareTypes: [NSArray arrayWithObject: NSURLPboardType] owner: nil];
to NSWorkspace -openURL:
