# install-macos-unsigned.sh
#
# Installs the unsigned macOS build of Claude Code Haha from a DMG that sits
# next to this script (download both from the same GitHub Release into one
# folder, e.g. ~/Downloads, then run this script).
#
# Because this release ships without an Apple Developer ID signature, macOS
# quarantines the download and Gatekeeper refuses to launch it ("damaged" /
# "cannot verify developer"). This script installs the app to /Applications
# and removes the com.apple.quarantine attribute so it opens normally.
#
# Usage:
#   bash install-macos-unsigned.sh                       # auto-pick the DMG next to this script
#   bash install-macos-unsigned.sh /path/to/Claude-Code-Haha-0.4.0-mac-arm64.dmg
