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
sudo mv icc-macos-arm64 /usr/local/bin/icc
xattr -cr /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. In the future, when icc is signed by an Apple Developer account, the input monitoring permissions can likely be restricted to icc itself instead of the whole terminal.
