Being knowledgeable about car engines doesn't magically make him
representative of all Macintosh users. I'm willing to bet most Mac users
know how to rename a file. Anyone who uses all of the above platforms on
a regular basis knows renaming files on macOS is just as simple as it is
on Linux or Windows. Click the file's name and you are in filename
editing mode - simple.

the problem is that he changed the file's extension and hide extensions
is normally on.

the same problem exists on windows but he's too stupid to realize what
the actual problem is and would rather just troll under yet another
nym.

This whole issue is just another bit of fallout from the Windows
nonsense of *requiring* a file extension.

yep.

classic mac os did not use file extensions. it used metadata,
specifically type and creator, which worked *very* well.

there was also a mechanism to automatically add extensions when
transferring files to other systems for compatibility purposes.

unfortunately, the rest of the world was stuck with extensions, so with
os x, apple decided to join the crowd.
