Yes, you can import MBOX files into Apple Mail with attachments intact if the MBOX file is properly structured and free of corruption. The manual import option works well for small and healthy MBOX files. By selecting Import Mailboxes from the File menu and choosing the MBOX format, emails are generally imported along with their original attachments, formatting, and folder hierarchy.
However, I have faced issues when dealing with large or slightly corrupted MBOX files. In some cases, attachments were not displayed correctly, or certain emails were partially imported. File size and data integrity play a major role in the success of the import process, and even a minor issue within the mailbox can cause unexpected errors.
To avoid such problems, I prefer using BLR Tools to properly prepare and manage MBOX files before importing, as also discussed in the blog.
