I am trying to update my software because certain sites I am trying to use aren't supported by the version of Safari I have on my Mac. I went to Software Updates, looked for any updates available but it is telling me that "there are no updates available." Clearly this notification is incorrect because I am not able to use a pretty common website on my laptop.
How do I resolve this?
MacBook Pro 13", OS X 10.11

If you wish, backup your Mac and upgrade macOS.
