Apple Mail stores a lot of data locally, including emails, folders, and attachments you have downloaded. None of that moves to a new machine just because you signed into the same Apple ID. This blog covers how to move Apple Mail to new computer the right way, without losing emails or breaking your folder structure. We will walk through the process using the Cigati MBOX Converter Tool. It helps you transfer data to a new machine accurately and intact.
Buying a new Mac is the most common reason people need to move their Apple Mail data. A fresh machine starts with an empty mail setup, and anything that was saved locally on the old computer simply does not appear. Local folders, archived emails, and offline data stay exactly where they were unless you take steps to move them across.
Hardware failure makes it more urgent to copy Apple Mail to new computer. When a Mac starts crashing, running slowly, or stops turning on altogether, your first concern becomes getting the data off before the situation gets worse. Emails stored locally are at risk in that scenario.
Work transitions also create this need. If your organization issues a new device, your personal mail setup, saved folders, and local archives do not carry over through a standard IT handover. You have to move that data yourself.
The Cigati MBOX Converter Tool takes your MBOX files exported from Apple Mail and converts them into formats you can actually use elsewhere. You can save to PST, EML, MSG, PDF, CSV, or migrate directly to Gmail, Outlook 365, Hotmail, Google Workspace, or any IMAP account. It works with MBOX files from Apple Mail, Thunderbird, Google Takeout, and several other clients. Before converting anything, you can preview your emails, attachments, and metadata. If the preview does not load properly, there is a browser view option that opens the email directly in your web browser so you can still check it.
It handles multiple files at once with no size restrictions. You can apply a date filter to pull only emails from a specific period and remove duplicate emails. Also, you can choose how attachments are handled, save them separately, keep them inside the email, or skip them entirely. There is also an option to merge MBOX files or split large ones into smaller chunks by size.
The free version lets you convert 50 emails per folder before committing to a purchase. A full step-by-step guide is covered in the next section.
Before moving Mac Mail to new computer, you first need to export your mailbox in MBOX format. Apple Mail provides a built-in option that allows you to save your emails locally. Once exported, these files can later be transferred or converted as needed.
Steps to export MBOX files from Apple Mail:
It is important to keep your email data safe. Does not matter whether you are upgrading to a new Mac, changing your damaged system, or otherwise. If you move Apple Mail to new computer, then it is not only about signing in with the same Apple ID.
The Cigati MBOX Converter helps a lot to move the MBOX file exported from your Apple Mail easily. It does not affect the folder structure and keeps everything intact. It has multiple saving options, and you can also directly import your files to other email clients.
