Apple mail export .mbox problem?

[okcomputer-1]

I am trying to migrate mbox files that I exported from the Apple mail software.
However, the system says can't process mbox files for user [e-mail]
And then says:

IOErrr: [Errno 21] Is a directory: "Users/.../..../ xxxxx.mbox'

I have the fear that the Apple does not extract compatible mbox files for the migration. Any help is welcome.

Can you share the full log file (after redacting any private information)?

The .mbox file you're looking for to import is inside the "xxxx.mbox" directory created by your Apple Mail export.

Note that importing large amounts of mail using IMAP (as that post suggests) isn't recommended, as Gmail IMAP upload limit is quite small - 500mb per day.

Also, that post suggests using a username+password, which isn't as secure as using OAuth (which Thunderbird supports).
