Ah, sorry! I got it backwards. Yes, I've been connecting my n900 to my Mac as an external USB drive, and that's also what I've been doing with bluetooth. I've never tried to do the reverse... Hmm. From a quick check of the website here (and a little browsing on my N900), it seems that (as shipped) the N900 has no clients for NFS, Samba, even command-line FTP. I am able to browse my Mac via FTP through the web browser though, so at least that is available. It looks like UPnP is also available, if you're wanting to use your Mac as a media server. But you can probably get client software for pretty much anything. (Except perhaps AFP. ) I guess the more important question is, in what manner are you wanting to share files from your Mac?
