QubKey for
macOS (Apple Silicon)

This application is not distributed through the App Store. You install the .dmg you download from this page. The download is a standard macOS volume image: open it, copy QubKey to Applications, then eject the volume.

1. Open the file QubKey_1.0.0_aarch64.dmg (double-click in Finder to mount the volume).
2. Drag the QubKey app into the Applications folder shortcut shown in the window, or into /Applications in Finder.
3. Eject the disk image from the desktop or the Finder sidebar when done.
4. If you use Safari or other browsers, you may have a quarantined download: keep using only this official page and the checksum below to be sure the file is genuine.

When you first open an app that was not installed from the App Store, macOS may show a message that the developer cannot be verified or the app is damaged. In that case, follow Apple’s guidance to open the app only if you trust this download.

Apple Support — open apps safely on your Mac

A common first approach: right-click the QubKey app, choose Open, then confirm. You can also use System Settings → Privacy & Security and, after a launch attempt, use “Open Anyway” for this app, as described in Apple’s article.

In Terminal, go to the folder that contains the downloaded .dmg, then run:

The printed hash must match the SHA-256 value on this page. You can also use: openssl dgst -sha256 QubKey_1.0.0_aarch64.dmg

We do not recommend turning Gatekeeper off globally. If a technical quarantine block persists and you are certain the file matches the published checksum, advanced users can look for documentation on the com.apple.quarantine attribute—only for software you trust. Prefer the official steps from Apple in the link above whenever possible.
