Howdy,

There are many systems where there is a high need for security. Even many Macs are in situations where security is needed. So TeX Live is set, out of the box, to allow for that.

Howdy,

The problem is that when you update the texmf.cnf files in the distribution could change under you. I'm not sure, but you MAY be able to put a texmf.cnf file which contains only that one change in  /usr/local/texlive/texmf-local/web2c and make sure you run

sudo mktexlsr

so that TeX ``knows'' it's there. Can't guarantee that works though.

Good Luck,
