You should remember that on the Mac OS the "/" separator between
directories is ":". Use e.g.

<<"System:Desktop Folder:Buchhaltungssachen:my file.txt"

"System" is the name of the volume, Desktop Folder the desktop (here you
can use the first level directory of your volume), Buchhaltungssachen a
directory on the desktop and "my file.txt" a file in it.

Another method is: You can set your current working directory to your
prefered directory.

You get the list of directories which are in your search path with:


Say e.g.

    SetDirectory["System:Desktop Folder:Buchhaltungssachen"]

With this command you set your current working directory and append it
to the search path ($Path).

If you want to remove the last entry of $Path you say


But be carefully. With SetDirectory[...] you append "..." to your $Path.
With ResetDirectory[] you remove the last entry in $Path. If you use
ResetDirectory[] multiple you can remove more entries... (which might
cause errors on Unix machines).

Kind regards, Harald
