Well, i wanted to import my .ogg and .flac into iTunes but … you know the story. After 2 days of trying to compile amarok with kde3 and making it run natively with quartz-wm, i gave up.
The next day i found this nice blog post about adding ogg and flac support to iTunes.
Just get xiphQT (0.1.5) and install it ( open the XiphQT-full.mpkg ). Next get the flac import component for iTunes (its the flac_import_0.5b1_p0.1.dmg ) and drag the FLACImport.component into /Library/QuickTime . Last get the set-OggS tool (its the set-OggS-0.1.dmg ) and place the “Set OggS.app” in your dock or somewhere else where you can easily drop files to. Quit iTunes and restart it.
Now, what do you have to do for importing .flac into iTunes …
At first drop the .flac files on the “Set OggS” application (on the icon, not into the window).
Next just drag the .flac files into your iTunes. It takes a while to import and the playback will stop during that import period. Starting the playback of a .flac file although takes a while.
But after all, the .ogg and .flac files are in the library and you can play em as easy as all the other content. Just needs some more work on importing stuffs. Worked for me.
