Download of Fast Mbox Editor 1.9 for Mac was available from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus.
From the developer:
This app can be an extremely handy tool for mbox bundles exported by Apple Mail or any other program using the "Export Mailbox" features. While Apple Mail takes a significant amount of time exporting the mbox files, this app can open them for viewing in a fraction of a second.
You may want to check out more software for Mac, such as BatchPhoto — Batch Convert, Resize, and Edit Photos, Fast Rabbit Typing or MBOX to Outlook Migration on macOS, which might be similar to Fast Mbox Editor.
