K2F Desktop Reader

Installing on macOS

Our builds are not notarized yet, so macOS may warn that K2F Reader is from an "unidentified developer." This is expected — not a sign of malware. We cannot remove the system warning until code signing and notarization ship (on the roadmap).

1. Open the downloaded .dmg and drag K2F Reader to Applications.
2. Do not double-click the app the first time. Right-click (or Control-click) K2F Reader → Open.
3. In the dialog, click Open. You only need to do this once.

Verify the SHA-256 shown above before installing. For a zero-friction experience today, use the web viewer instead.
