I don't know the default OS X client so I can't go into detail, but I'd guess that one is better integrated with OS X. On the other hand, Thunderbird works cross-platform and allows you to choose any operating system without having to consider a new mail client, set it up and learn new ways. You could probably even copy over your data folder and resume working without any set-up (`scp -r ~/.thunderbird user@newpc:` would be the complete migration process, assuming it works between OSes).

You're correct. You copy the profile folder and set the default profile startup to be the one you copied (I think this was in the profile.ini file) and it is if you never left. I this this between mac, linux, and windows machines and it functioned perfectly every time including add-ons, settings, filters, and themes.

What OS did the profile start on?

I copied my profile from Windows to Mac, and everything is fucked up. Because of the different line ending characters, as far as I can tell.

The command I posted would copy the parent folder, including profile.ini, but yeah it's pretty much the same thing.

Cool, that's good to know for sure!
