Very helpful. Thanks.
If you want to port over track metadata and cover art too, https://superuser.com/a/543662 is even handier.
You may also use iDealshare VideoGo to convert FLAC to ALAC without quality loss.
It also helps to convert ALAC to FLAC and convert between FLAC, ALAC, M4A, WAV, MP3, AAC, WMA, OGG, OPUS etc
It also helps to extract FLAC, ALAC from video files or convert between video formats.
Here is the easy guide https://www.idealshare.net/audio-converter/flac-to-apple-lossless.html
I don't think you need Homebrew or to install anything... here's how I do it on Mojave and Catalina:
export IFS=$'\n'
for x in `ls *.flac`; do afconvert -v -f m4af -d alac $x ${x%flac}m4a; done
absolutely perfect. Had no idea afconvert
just existed like that! Thank you.
