yep. The only thing that's presented as a difference is a regular periodic update cycle, which is not really necessary as Mac security vulnerabilities are few and far between at this point. The other difference is code auditing, but given that OSX was re-written using UNIX ( designed as a multi-user OS from the ground up ) as a base, I don't think the criticism applies.
