Nothing seemed to help as far as getting my profile over the network share.
OSX would not let me copy all of the profile directory.
Thanks for all your suggestions, however.
I got so frustrated, I decided to just burn a DVD and see if this worked any better.
Well yes and no.
I easily copied the Thunderbird profile into place. But then all files and subdirectories were read-only, so I had to dig out a unix book and figure out how to recursively change permissions (chmod -R u+w). I also had struggles with figuring out how to create a thunderbird profile and then substitute my old one for it.
NOW I have a new problem still bugging me which I will start a separate post for. (In short, I installed thunderbird but I'm not sure it's really installed because the disk image keeps reappearing even after I eject it. Thunderbird comes up, but it seems like it's reinstalling it or something.)
With regard to this POST I still would like to get an answer to how to properly use a network share since I had to completely workaround it. I know I'll need this again soon.
Thanks.
