I want to share one Mac Address Book betwen two users and would rather not use the .mac solution. I asked a question here and one of the posts directed me to: http://www.macosxhints.com/article.p...41202101923651 I'm a bit concerned that this advice is almost four years old and no one seems to have tried but I figure I'll give it a go. I have an external HD with a partition with the permissions marked as suggested but then I get to the advice: "make a symbolic link from the new location of the master Address Book folder. Symbolic links are made in the Terminal: ln -s path_origin path_alias." And I have no idea what this is or how I would do it. Do I just open terminal and type that line? I can barely spell USB -- is this symbolic link solution too techy for me? Or can someone talk me through. Thanks!
