MAC HELP

Open an MSG file on your Mac.

Microsoft Outlook messages use the proprietary .msg format, which macOS does not open natively. MSG Opener reads the message directly in Safari or another modern Mac browser without requiring Outlook or uploading the email.

How to open it

1. Save the MSG attachment to your Mac.
2. Open MSGOpener.com in Safari.
3. Drag the file onto the opening area or choose it in Finder.
4. Read the message, view attached emails and download the attachments you need.

Why local processing matters

Business and personal messages can contain confidential information. MSG Opener processes the selected file on your Mac. The message is not transferred to our server.
