[数码手机] ios18和macos15的iPhone镜像功能除了wifi为何还要互连蓝牙？

iPhone Mirroring system requirements
iPhone Mirroring can be used with only one Mac and one iPhone at a time. Your devices must meet these requirements.

• Your computer is a Mac with Apple silicon or Mac with the Apple T2 Security Chip and is using macOS Sequoia 15 or later.
• Your iPhone is using iOS 18 or later.
• Your iPhone and Mac are signed in to the same Apple Account using two-factor authentication.
• Your iPhone and Mac have Bluetooth and Wi-Fi turned on.
• Your iPhone is locked and near your Mac. It can also be charging and using StandBy.
• Your iPhone is not sharing its cellular connection (Personal Hotspot is not in use).
• Your Mac is not sharing its internet connection or using AirPlay or Sidecar.

这是苹果官方给出的运行需求。蓝牙WIFI是必须，且iOS设备必须锁定并靠近Mac。在PS5都可以串流的情况下，iPhone通过WIFI串流不应该有技术难度，靠近这个需求大概率是出于安全考虑，而蓝牙正是可以100%确保设备是物理靠近的。
