Open-EID

The package provides drivers and software components that enable the use of Estonian national ID‑cards on macOS systems. It includes web authentication extensions for browsers such as Chrome, Firefox and Safari, as well as signing libraries that allow digital signatures to be created with the ID‑card. The distribution also bundles the DigiDoc4 application for handling electronic documents and performing cryptographic operations.

Target users are individuals and organizations that need to authenticate to online services or sign documents using the Estonian ID‑card on macOS. The software supports recent macOS releases (Ventura, Sonoma, Sequoia, Tahoe) and is offered as a stable, regularly updated release. Installation is performed via a simple download from the official site, followed by on‑screen prompts.

What distinguishes this offering is its focus on a single national authentication method, providing a unified set of drivers, browser extensions, and signing tools that work together to enable ID‑card based authentication and digital signing on Apple computers.
