Actually patch Tuesday is going away as windows becomes a service and they don’t want to wait to release patches as 0 day exploits are more common. They are getting faster and more efficient. Exactly the opposite of Apple.
You don't know what you are talking about. Apple pushes updates for portions of OS X as they are available, they don't wait for any schedule or for major update and they are installed silently in the background for the majority of most users. Security updates are mostly handled this way. A user can opt to give permission for every update, but most don't. It is only when there is a major point upgrade that Apple requires permission.
