FLAC - Playing in iTunes/Quicktime Mac

How to add FLAC playback to iTunes on OSX, without converting the FLAC to another format. Adds quicktime support for FLAC in the process.

First, download the latest version of XiphQT from here. 

• Copy the XiphQT file from the dmg to
• /Library/Quicktime/ (right on the hard drive) and
• ~/Library/Components (inside your home/user folder).

You will also need to downloadhttp://people.xiph.org/~arek/flac_import/flac_import_0.5b1_p0.1.dmg.

• Copy FLACImport component from the DMG to the same places as the XiphQT file.

Finally, download http://people.xiph.org/~arek/flac_import/set-OggS-0.1.dmg.

• Open it and put the Set OggS app in Applications (or anywhere really). You probably should put the Set OggS app in the dock, or on the desktop as well: you'll be dragging your FLACs into it.

Reboot your computer.

• Test opening a .FLAC file in Quicktime player to make sure you've got it all installed right 
• If it works in QT, you're done. You can now drag .flac files onto Set OggS in the dock, wait like 10 seconds, and then drag directly into an iTunes playlist

[Info taken from:here . It explains the procedure in lot more detail, with extra steps at the end to convert your flacs to Apple lossless (ALAC/.m4a). if desired.

Update 1: Great news! The webpage referenced above (and here) now has a much easier way to do this. The author has created a freeware app that combines all the stuff in this tutorial, and works in a simpler, more Mac-like way. Check it out.

Update 2: The site for this freeware app is now here.
Update 3: Mac OS X 10.7 Lion Support: is incomplete at this time. To make Fluke run, go into your Applications, right-click on iTunes, head to Get Info, and check off "Open in 32-bit Mode".
