How can I convert an MBOX file?

If you’re working on macOS and want an easy MBOX conversion tool, this helped me. I used MacGater MBOX Converter when I needed to import MBOX to Apple Mail, and it worked great without needing Outlook. It lets you choose between loading single files or whole folders, which is helpful when managing bulk email. The interface is super clean, so even if you’re not a technical user, you’ll get through it easily. It supports all the major Mac versions, including Monterey, Big Sur, Catalina, and more, and handles multiple MBOX sources like Thunderbird and Google Takeout.
