Appendix B. Troubleshooting

Whether it’s a car engine or an operating system, anything with several thousand parts can develop the occasional technical hiccup. OS X is far more resilient than its predecessors, but it’s still a complex system with the potential for occasional glitches.

  • Quit and restart the wayward program.

  • Log out and log back in again.

It’s the other problems that’ll drive you batty.
