  • First, open the ProtonMail Bridge app and head to Email Clients> Configure.
  • After that, choose Apple Mail from the “Select your email client” menu.
  • Then, since security is important, you’ll need to install a special certificate for ProtonMail Bridge. Click “Install the certificate” when prompted.
  • Now, your Mac settings will open. Go to “Downloaded” and double-click your ProtonMail profile.
  • Next, click “Install…” followed by “Install again” to confirm.
