This question already has an answer here:

On MacOs X running updated mactex packages, when I compile my biber file I get this error:

data source /var/folders/yf/y69gwrx12kj2jtzrs78vg2vm0000gn/T/par-67696f6e61/cache-    23e542f078c05cf97a78083ff4d628bc746d389d/inc/lib/Biber/LaTeX/recode_data.xml not found in .

Any idea on how to solve it?

    It's very easy to solve it, actually. :) Remove the problematic folder (the one with /var/folders/yf/y69gw...) and run biber again. :) – Paulo Cereda Nov 30 '12 at 14:43

    As Paulo said, this is usually due to interrupting biber on its first run (of a new version) so that it doesn't unpack properly. Just delete this folder: /var/folders/yf/y69gwrx12kj2jtzrs78vg2vm0000gn/T/par-67696f6e61 and run biber again once without interrupting it (just with no arguments for example) to make sure it unpacks correctly. – PLK Nov 30 '12 at 18:20
  • I had different folders (no yf) under /var/folders/, but I just ran a sudo rm -R * and it solved my problem. Thanks. – Jonathan Komar Feb 10 '13 at 11:26

    I also found this answer helpful... and the exact answer from @PLK sorted me out. So, I don't think it's too localized - though perhaps the wording of the question is overly localized. – Dav Clark Jun 30 '13 at 2:01
