How to tunr FLAC into Apple Lossless

If you go to the "Preferences" dialog box in iTunes (under the Edit menu), click on the 'Advanced' tab, then on the 'Importing' tab you'll see the choices for importing files. The possiblities are AAC, AIFF, Apple Lossless, MP3 and WAV.

If you import WMA files into iTunes, and you have set the iTunes preferences to use Apple Lossless as the import format, iTunes will convert the files on import, after asking your first.

In the "View options" dialog box under the "View" menu you can click on "Kind" and the file type will show up as one of the columns you see alongside each song that's been imported, a nice feature if you have a mix of file types because you can use that column to sort the songs.

Not sure if this will work with your Mac ( OS X 10.4.9 or later).

I was surprised with the quality and versatility for a freeware download.
Hope this helps.

Thanks everyone for your help! I'll experiment a bit to find which one works best.

Max is the way to go, I use flac on my pc at home and apple lossless on my mac at work. My 8 way mac pro processes 8 songs at a time and can rip through gig's of files in a flash. The best part is that unlike some programs on the pc side max transcoded files are compatible with itunes sharing so you can listen to them on other computers or a itv.

Is AIFF a lossless format or is that full size like WAC files? I ask becasue if it is not lossless, I'm not sure I have the HD space to do the conversion, unless I do a few at a time I guess.
