macDNIe

Your DNIe and your Mac, finally on speaking terms. macDNIe reads your card, identifies you on Spanish e-government portals and signs documents in the standard European formats — without a single byte leaving your machine.

The Spanish DNIe,
native on macOS

The DNIe is Spain’s electronic national ID card. Getting it to work on a Mac has always meant fighting middleware. macDNIe replaces that with one app: insert the card, enter your PIN, and your browser or AutoFirma sees the certificates.

Identify and sign

Every standard format, every browser

macDNIe establishes the CWA-14890 secure channel with the card and exposes the certificates to the system.

  • Signatures in PAdES, CAdES and XAdES, with RFC-3161 timestamps
  • Safari, Chrome and Edge via CryptoTokenKit
  • Firefox via a bundled PKCS#11 module
  • Compatible with AutoFirma

Nothing leaves the Mac

No servers, no telemetry, no identifiers

The card is read locally over PC/SC and everything is processed on device.

  • Your PIN travels inside the encrypted channel and is never stored or logged
  • No analytics, no device identifiers, no accounts
  • The only outbound calls are OCSP certificate-revocation checks and optional TSA timestamping

Built for people who actually have to use it

Anyone in Spain with a DNIe and a Mac: filing with the Agencia Tributaria, signing with the Seguridad Social, submitting to a regional administration, or signing a contract that has to hold up legally.

Supported languages

The interface ships in the four co-official languages of Spain — español, català, euskara and galego. macdnie.com is published in Spanish and English.

Requirements

macOS 13 or later on Intel or Apple Silicon, plus a USB contact smart-card reader (CCID class).

Availability

Coming soon to the Mac App Store — the app is currently in review. Pricing is €10/year as an in-app purchase, or €150 for a lifetime licence. A direct-download edition is planned for Firefox users.

macDNIe is an independent product by Nexo Apex S.L. It is not affiliated with, nor endorsed by, the Dirección General de la Policía, the Ministerio del Interior or the Government of Spain.
