[tex-live] mactex installer overwrites excalibur dictionaries

[Richard Koch]

Hi,

We thank Sven for his bug report on the tlpretest Mac installer, which will be fixed.

Just a word to other Mac people, who read with some alarm that the installer "overwrote" personal files in /Applications/TeX. The Apple software which does the hard work of unpacking the distribution does not overwrite extra user files it doesn't recognize. Sven's problem was caused by a postinstall script I wrote which attempted to clean up /Applications/TeX and wasn't as careful as Apple. Just cleanup operations are very rare in MacTeX, for reasons that the current example makes clear.
