Someone online was asking how to get this running on a Mac. Here is a simple script, save it as run_taxinaut.sh in your Taxinaut directory, then run "sh run_taxinaut.sh".
#!/bin/sh
# Taxinaut is a wonderful game, but it doesn't officially support mac.
# Run this script to launch Taxinaut properly on macOS.
# Always run from the directory where this script lives
cd "$(dirname "$0")"
TOKEN_FILE=".taxinaut_mac_approved"
# If token file does not exist, remove quarantine attributes
if [ ! -f "$TOKEN_FILE" ]; then
echo "First-time setup: approving Taxinaut for macOS..."
# Remove quarantine flag recursively from this directory
xattr -dr com.apple.quarantine . 2>/dev/null
# Create token file so we don't repeat this
touch "$TOKEN_FILE"
echo "Approval complete."
fi
# Launch Taxinaut
java -Xmx2000M -Xms2000M -XX:+UseParallelGC \
-cp "taxinaut.jar:lib/*:mod/mod/*" \
net.mosgrom.taxi.Taxi "$@"
