Small (but IMHO important detail). The above quote of me confused me. There
was quite some other stuff between the first part and the last sentence. At
least something like "[...]" would have indicated that.

Sorry, I don't understand this even after reading it three times. Let's try it
a last time ;-) ... Some "KDE apps form an ensemble one could think of as the
KDE Desktop for <some OS>". I don't think so. Plasma is (currently the only
but that might change) the KDE Desktop. But Plasma is even more...

What's this kde4-workspace? A Macports module? Don't find it e.g on
Oh and there is no "KF5 Workspace". You might mean Plasma 5. Which is based on
KF5, but it's based on Qt5 as well and not called "Qt5 Desktop" because there
are other "Qt5 Desktop" IIRC like lxqt or hawaii or so. And they might even
use KF5, at least some of them.
KF5 Workspace depends on Plasma??? DrKonqi is afaik in Plasma and that might
need to be changed. But that's probably for another thread. And we (KDE)
should probably check other bug-report-tools or crash-tool. But other thread,

Makes sense to me too.

"KDE" refers to the KDE community, the people and thus "KDE 5" would be a
"version 5 of the people"???

I just know Debian and there "kdelibs5" packages:
But that's different and has nothing to do with KF5 or Qt5. It's actually
"kdelibs4" and thus Qt4 based. Do you know anything else? Could you send some
links? Seriously I'd be interested.

I think (but might be wrong) what's missing here is the fact that you can (and
should) use only some of the frameworks in KF5. That's an important point of
the modularization of kdelibs to KF5. So you don't either use KF5 or not but
you might use (to take David's example) Sonnet in Scribus (and thus use KF5)
or in Dolphin you might use quite some more KDE frameworks (KArchive, Kio,
KConfig, etc.) but not Sonnet. (Just examples, I did not check the actual
dependencies of these apps).

In the end all should be "just" Qt apps. Some of them use Qt and some other
libraries, some use just Qt and some use Qt and some libraries from KF5.
Everything should work as good as possible for our user on Mac and Co ;-).

Sorry then, your "...which AFAIK was done without feedback from KDE-Mac users
(most of the few of whom were probably unaware of what was going on)..."
sounded to me like that.

Fortunately this changed meanwhile :-).

Indeed. That might have happened. There might have been other missings but we
managed to get a KF5 out and more releases and we're working on getting it
better on Windows and Mac (and more) and so let's fixed it here and now and
work into the future rather than bringing it up and again what we've done
wrong back then. It's honestly a bit tiring to always repeat this.

So if I get this correctly there is really something wrong with Mac menus in
Qt apps and it should be fixed (rather the patched). Please do it (ok, you're
already on it so thanks).

So we really need to get KF5based apps running on Mac. But therefore we need
the QSP patch upstream which is being worked on. Great. We'll be there
