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.

FYI - Safari for Windows doesn't exist anymore (when it did, it used a separate Windows app called Apple Software Update). Safari on the Mac is updated through the Mac App Store. – daGUY Jan 2 '13 at 21:59
Safari 5 still exists (surprised you can still download it!). Safari 6 (the current version) is only available for the Mac. – daGUY Jan 2 '13 at 22:08
Feel free to ask a second question on windows Safari. We prefer one question per question, and asking another is free. – bmike Jan 2 '13 at 23:45

In OS X, Safari is updated via the normal system bundled software update process. On Lion, this is the Apple Menu, Software Update tool which can be scheduled or disabled.

On Mountain Lion, this function remains in the Apple Menu, but runs through the Mac App Store app

In the end, both tools call softwareupdate binary that you can also run from the command line.

This differs from your Windows experience where the Apple Software Update tool runs to update all Apple software (Safari, QuickTime, iTunes, etc.) since it is not part of Microsoft's software update process.
