[R-SIG-Mac] Case distinction on a Mac.

[Kasper Daniel Hansen]

It is pretty easy, you just need to reformat your mac (and therefore  
move everything of it, as well as re-installing everything). When you  
reformat you will be asked what file system you want, so it is in  
principle dead easy.

Some mac software needs HFS though, at least as far as I understand.
