method provide an alternative interface to the

On Mac OS (Classic), the path separator is ':', not '/', and the current directory is denoted as ':', not '.'. You should be careful about specifying relative pathnames. While a full path always begins with a volume name, a relative pathname should always begin with a ':'. If specifying a volume name only, a trailing ':' is required.
