Steps

1. Create an executable script to run in foreground and manage colima:

cat <<-EOF | sudo tee /usr/local/bin/colima-start-fg
#!/bin/bash

export PATH="/opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"

function shutdown() {
  colima stop
  exit 0
}

trap shutdown SIGTERM
trap shutdown SIGKILL
trap shutdown SIGINT

# wait until colima is running
while true; do
  colima status &>/dev/null
  if [[ \$? -eq 0 ]]; then
    break;
  fi

  colima start
  sleep 5
done

tail -f /dev/null &
wait \$!
EOF

sudo chmod +x /usr/local/bin/colima-start-fg

2. Create a launchd agent to run colima automatically:

cat > $HOME/Library/LaunchAgents/com.github.abiosoft.colima.plist <<-EOF
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>Label</key>
    <string>com.github.abiosoft.colima</string>
    <key>Program</key>
    <string>/usr/local/bin/colima-start-fg</string>
    <key>RunAtLoad</key>
    <true/>
    <key>KeepAlive</key>
    <false/>
  </dict>
</plist>
EOF

launchctl load -w $HOME/Library/LaunchAgents/com.github.abiosoft.colima.plist
