Hi Roussanka,
I’d say that with your report this is quite final. Just two comments:
1. If you haven’t already done so, you may try to open a file in Aquamacs from the Terminal with
open -a aquamacs <filename>
then Aquamacs should pick the right PATH from the environment.
2. the directory service command was to make sure about the shell that you were running (just in case Terminal launches another one, for example). The syntax is correct (of course, replacing <yourusername> with your actual username). It is documented in a man page. It’s also case sensitive in the variable names.
