TL;DR: osx and mac are a complete mess. What should we do about that?
What's the current situation?
Per this question, we've established the following distinction between the "OS X" and "Mac" tags, more than two years ago:
Mac OS X is a Unix-based operating system developed, marketed, and sold by Apple Inc.
Questions about Mac hardware, sold by Apple. Use osx for the operating system, and use mac-address for MAC addresses instead.
Now, this works in theory. We get a nice differentiation between Mac hardware and the operating system that runs on it. t But at the same time, we have 4,664 Mac questions and 8,026 OS X questions, with 1,995 questions overlapping. I dare to say that a considerable amount of all "Mac" questions are not related to hardware at all and actually should be tagged "OS X" instead.
But why is that? Here are a couple of possible reasons:
Apple popularized the "Mac" label for anything that is "not a PC". Since Macs typically run only with OS X, people referring to Mac actually mean the operating system, not the underlying hardware (MacBooks, iMacs, etc).
Some software vendors target the "Mac" platform instead of labeling it "OS X", including Microsoft, who sell "Office for Mac" and not "Office for OS X".
The app store for OS X is often called "Mac App Store".
People don't read tag wiki excerpts. cough cough
The gist of all that is: We have so many questions tagged with mac that are not about hardware. Not at all.
But what can we do?
More than two years ago, Ivo Flipse ♦ said:
A distinction between OSX for software and Mac for hardware would be more clear (just one hell of a job ;-) )
That was long before we had so many affected questions – so as a matter of fact: We were never able to keep up with making that distinction clear.
So, what should we do?
delland all the other completely useless company tags are removed. While not much better, given it's the common brand name for all their computers, there's actually some cohesion between Macs through similar functionality and features.
