Hello!
I install to my mac KDE 4.12 website. But KDE 4.12 apps (website paket) not enough for me. How i get more KDE programs on OSX. Example K3B. Or How I build sourcecode kde software (example kde-apps.org software) on osx native programs. Help me!. I do not find any answer to anything. I think that someone else has wondered the same things.

The K3B KDE4 port is not finished yet, so the stable release won't be available on mac right now. There is maybe a build of the current alpha2, but I don't use mac, so I can't say what is available there.

Edit:
Build instructions for Mac can be found at the techbase:
http://techbase.kde.org/Getting_Started ... 4/Mac_OS_X

Install macports, then in the terminal do
'sudo port selfupdate && sudo port sync'
'port search kde' to see kde packages available, then go wild.
'sudo port install PACKAGE_NAME' will install them.

If you become sufficiently motivated, you can even submit portfiles yourself.
