I was reading through the On-Topic page of your help center and noticed this line:
- The Unix foundation underlying MacOS (but generally not frontend application questions)
Which was what I was looking for and answered my question about scope. But, it's kinda inaccurate. The OS name is no longer MacOS (hasn't been for ages), and Mac OS X was phased out two years ago - meaning the correct name is now "OS X".
Could the help center be edited to reflect this?
