Best software to convert FLAC to Apple lossless?

I use MAX as well, with "Full Paranoia" on-always (CD Paranoia error correction). I agree though; it is not the most intuitive interface.

What is the website for MAX?

If you are going the MAC route, why do you want to convert to AIFF or Apple Lossless. Use Songbird instead so that you can play your Flac files with your MAC. No need to convert. I use to convert them with MAX so i can play them with Itunes but now i use Songbird instead.
Have fun.

smoffatt - the reason i use apple lossless and itunes is because i use pure music. i only use itunes as the database and the presentation layer, pure music actually reads the music. you would need need to compare the itunes interface using pure music or amarra ripping with max or xld vs. some other interface (songbird) with flac to see if there was any improvement in sound and functionality.
