I did the same for the settings and got the "No Application or file to import data from was found" error message. Got the No Mailboxes were found in the import message. Then decided to try to import just the Mail. then went to tools/import and noticed I didn't have the the option to Import Everything. Chose not to make it my default because I want to make sure it works first. I then downloaded and installed Thunderbird 60.31.1. I then used App Cleaner to delete the ten year old version of Thunderbird and the support files that were not part of the library folder, such as the actual application, Thunderbird. I use my email local folders extensively as a type of database to keep a history of purchases and other important information in the local folders. I did this because most of my logins and settings have changed a lot and I want to import the current local folders and settings from the current version of Apple Mail. Before installing the new version, I opened the old version of Thunderbird, went to the Tools/Account Settomgs and found the directory in the Mac OS library that needed deleted.

A little behind the times, but I have been using apps that wouldn't run on the newer Mac OS. Especially after reading that Thunderbird could now share both iCloud's Apple Calendar and Contacts. I use Thunderbird at work and decided I miss some of the more advanced features that are not in Apple Mail on my iMac at home. (I posted about this here and here on the Thunderbird support forum.Maybe 10 years ago I used Thunderbird on my iMac. If you have a lot of messages and special needs, the $25 for Emailchemy is money well spent. It hung on a few folders that were already corrupted, but the author seems willing to help even before I paid for it. Googling found "Sven" who had the same problem, and he recommended Emailchemy it knows about Mac Mail and Thunderbird, and it converted 44,000 (!!) cached Mac Mail IMAP messages into Thunderbird format, even preserving the folder hierarchy. I could probably glue them together myself, but the hard part would be finding the messages it couldn't read and dealing with issues like attachments and multi-part messages. So each CachedMessages folder is sort of like a maildir folder, but wouldn't process them. The Mac Mail in Mac OS X 10.3 Panther keeps a local copy of each message as. None of this worked for the IMAP server messages. I did get it to concatenate and remove duplicates from some mbox files.

It uses the old Mail::Folder module, and when I reported bugs and fixes in this I found its maintainer "kjj" has vanished.

Installation of this on Cygwin and recent Perl was a bear. I had a lot of duplicate e-mails, so I found a free script. I discovered the hard way that this only works for top-level files, not subdirectories. Many of the Mac Mail folders contained mbox files that I could simply move into the Thunderbird directory in C:\Documents and Settings\S Page\Application Data\Thunderbird\Profiles\ fault\Mail\Local Folders and T'bird would spot them upon restart. So I decided to move the mail into Thunderbird's folders. But Google Desktop search wouldn't find words in them.

I transferred my mail files to this Windows machine and installed the fine free Thunderbird mail program, but it has no Tools > Import > Mac Mail option.įor a month I tried just leaving the Mac mail files on-disk. I organized many of my e-mail on a Microsoft Exchange IMAP server at work, access to which I lost at the same time The Man pried my Mac Powerbook from my cold, dead fingers.
