An OSX code sketch is available here (summary: call FSPathMakeRef to get an FSRef from a path string, then FSRefMakePath to make it back into a path, which will then have the correct case). And note that it only works if the file actually exists. http://stackoverflow.com/questions/370186/how-do-i-find-the-correct-case-of-a-filename It would indeed be useful to have that be available in Python.
