Yes, that's the "carbonised" Emacs, hence Carbon Emacs, I am talking
about.

Not to worry. It may seem confusing, but it is actually quite simple.

OSX has the ability to run programs written for different APIs and
GUIs.

The native GUI is called Aqua and it uses an API called Cocoa, which
is based on OpenStep/GnuStep. Then there is another API called Carbon,
which allows some backwards compatibility to the legacy MacOS before
OSX. Applications that use the Carbon API can -in principle- run on
both legacy MacOS and OSX/Aqua. Applications that use the Cocoa API
cannot run on legacy Macs, but they could be recompiled to run under
OpenStep or GnuStep.

(Quartz is just a rendering engine inside Aqua, lower level so to
speak, not of concern in this context)

Then there is X11. X11 apps can run under OSX, but only if you install
the X11 GUI in addition to the default Aqua GUI.

Thus, if you have an application that has been ported to Aqua (ie
Emacs), then there might be things that are different and in order to
isolate a problem, it is important not to take things for granted just
because they are fine in another version of the same software.
