cannot migrate apple mail files
I have successfully migrated from Apple Mail to T'bird but with one major outstanding problem. It has imported mail files up to 2012 which I thought were long gone but nothing since then. In other words, it has found files that were deleted from Mail way back but has not imported the current files. It is filing new mail as it comes in but I am having to keep Mail running to find recent files. Import says all files have been imported.

There is a discussion of importing from Mail app here:

It appears you can Export from Mail to a folder that contains the kind of mbox file that can be imported to TB.
