icc (CLI) — macOS

Quick install

curl -fsSL https://instacrypt.io/ic-cli/install.sh | bash

Detects Apple Silicon vs Intel, installs icc, sets up PATH, and clears the Gatekeeper quarantine flag for you.

Manual

Grab the binary for your Mac:

icc · Apple Silicon

macOS arm64

icc · Intel

macOS amd64

Or browse all releases.

chmod +x icc-macos-arm64
xattr -d com.apple.quarantine icc-macos-arm64
sudo mv icc-macos-arm64 /usr/local/bin/icc

Hardware keys

YubiKey challenge-response on macOS requires the Input Monitoring permission (System Settings → Privacy & Security → Input Monitoring) for the terminal you run icc from — the YubiKey's OTP interface is a keyboard, and macOS gates it. This is the same permission ykman and KeePassXC need.
