doozy, it's good to be careful and it's always better to have a look first - however it should be save to run entire folders through Maconverter, and some of the options (like the MacBinary fix) may affect/repair all sorts of files, including docs, pictures, etc. Macinstaller (as mentioned above) only installs libraries plus files directly referenced by them - any additional textures or "morph target only" .obj's will not be touched or copied.
