We tried using standalone pinentries for this, but couldn't get that working with Thunderbird on macOS, so in the end, we chose GPG Suite . So, replace the brew command from the guide with this: # If you want to use Apple Mail rather than Thunderbird, try gpg-suite or gpg-suite-nightly instead, note you need to pay to activate the Mail extension, iirc brew install gpgme ykman gpg-suite-no-mail Now, Tanny said also don't make this a literal PIN, use an actual passphrase...
