Open P7M files on Mac
On Mac, .p7m files do not open in Preview. The quickest way is the browser: open our page in Safari or Chrome and drop the file in the marked area.
Step by step
- Save the .p7m attachment to your Downloads folder (from Mail, Outlook or your webmail).
- Open the home page and drop the file, or press “Choose files”.
- Check signer, certificate and preview; if you need the full document, unlock it and download the PDF.
If Mail shows an .eml file instead of the .p7m
Sometimes the Mail app shows the signed attachment as .eml. In that case download the message from your provider’s webmail: there the .p7m attachment is available as it is, ready to open here.
