How is Safari updated in OS X? I know this seems like a simple question, but I cant find any good documentation on it. I know of a software update tool that would prompt you for updates on windows, but I would like to know how this is currently done on OS X.
The reasoning for my question is I am comparing browser auto-update functionality and am working on documentation to support plans to guarantee certain extents of browser compatibility for a product. The documentation for Safari seems a little lacking so pointers to an authoritative source would be most welcome in addition to an answer from experience.
