Appendix B. Troubleshooting & Maintenance
The iPhone is a computer, and you know what that means: Things can go wrong. This particular computer, though, is not quite like a Mac or a PC. It runs a spin-off of the macOS operating system, but that doesn’t mean you can apply the same troubleshooting techniques.
