[XeTeX] Don't update to Mac OS X 10.6.7

[Mojca Miklavec]

Hello,

I'm sorry for cross-posting, but this issue is a really nasty one (and
might come too late for some). If you use OpenType fonts in your TeX
documents, don't update your Mac OS X unless you want to have some
serious fun with printing ...

... a workaround that worked for me (for PostScript printers only) was
the following: I used
      http://localhost:631/help
for help and ended up doing
   lpstat -p
to get printer name and then
   lp -d some_very_weird_printer_name_ myfile.pdf
to send the file to a PostScript printer.

I wasn't sure whether it was an OS issue or LuaTeX issue (I updated
both), but Florian on ntg-context mailing list posted the above links
which most probably makes XeTeX users vulnerable as well.
