「アップグレードしたiPhoneまたは新しいiPhoneのミラーリングが機能しない」問題を解決するには？

Many users enjoy mirroring their iPhone screen to a Mac or other devices because it makes multitasking easier. Whether you want to reply to messages, watch videos on a larger display, or manage notifications without picking up your phone, screen mirroring provides a seamless way to stay productive. However, after updating iOS or macOS, some users discover that iPhone Mirroring suddenly stops working.

After a system upgrade, compatibility glitches, connection errors, or temporary bugs may cause iPhone Mirroring to stop working, leading to issues such as the iPhone not appearing in the mirroring list, connection failures, or unexpected disconnections.

Fortunately, there are several ways to fix the issue. In this guide, we will explain what iPhone mirroring is, why it may stop working after an update, and the practical solutions you can try.

1. What Is iPhone Mirroring?

iPhone Mirroring is a feature introduced by macOS Sequoia that allows users to control and view their iPhone directly from a Mac. With this feature, your iPhone screen appears on your Mac desktop, enabling you to interact with apps, notifications, and messages without physically using the phone.

Unlike traditional screen casting, iPhone Mirroring provides full remote interaction. This means you can click, type, and navigate apps using your Mac’s keyboard and trackpad while the iPhone remains locked nearby.

Key Benefits of iPhone Mirroring:

• Convenient multitasking: Use iPhone apps while working on a Mac.
• Better productivity: Reply to messages or manage notifications quickly.
• Larger display: View iPhone content on a bigger screen.
• Seamless Apple ecosystem integration: Works smoothly with Apple’s Continuity features.

However, because this feature relies on network connectivity, device compatibility, and system stability, software updates may sometimes interrupt the connection process.
