Just a note for other people that might be cracking their heads trying to meld MacRuby and NSError ** parameters. The answer was already sitting on my computer, I just never through to look at the MacRuby Core Data XCode templates, but that’s beside the point. For those of you searching, you just need to do the following.
error = Pointer.new_with_type(‘@’)
unless managed_object_context.save(error)
NSLog error[0].inspect
NSApplication.sharedApplication.presentError(error[0])
end
unless managed_object_context.save(error)
NSLog error[0].inspect
NSApplication.sharedApplication.presentError(error[0])
end
The NSLog error[0].inspect will output #<NSError:0x80057a640>. Exactly what we want.

Thanks for posting this.
For anyone cutting-n-pasting note that the quotes around the @ in the Pointer.new_with_type line will need to be changed from smart/curly quotes to standard straight quotes. Otherwise you get: undefined method `‚Äò’
