Howdy, A problem updating via TeX Live Utility (i.e., tlmgr) on Mac was reported to us at MacTeX-support. It seems that <ftp://ftp.tu-chemnitz.de/pub/tex/systems/texlive/tlnet/tlpkg/texlive.tlpdb> is completely offline and it isn't clear when it's coming back. Good Luck, Herb Schulz (herbs at wideopenwest dot com)
