  Talking about macOS and OS X with the new naming scheme
  
  In case you haven't heard, Apple have decided to rebrand OS X to macOS. This will start with the next version of the OS, macOS Sierra.
  This means that while this version is OS X 10.11 El Capitan, the next is macOS 10.12 Sierra. I can understand why they've chosen this for marketing purposes, though I predict that we're going to see some confusion and convolution in future discussion about the OS.
  I'm raising the point so I (we) know how best to discuss OS X/macOS in the future. 
  Will this involve:
  
  Incorrectly: Retroactively talking about all OS X versions prior to 10.12 as macOS.
  Stubbornly: Continuing to call it OS X regardless of what Apple has decided for continuity's sake.
  Correctly: Calling them what they were released as (OS X up to 10.11, macOS afterwards) and hoping that the community correctly self calibrates to the change.
  
  I'm keen to see what you all think so that future questions and answers can hopefully avoid this kind of fragmentation between the various naming schemes.

  For versions before Sierra, it's OS X. From Sierra moving forward, it's macOS.
