tonoon OP @misaka19000 听过一种说法，通过 Mac 与数据中心匹配可以向其营销广告。所以 iOS 系统增加了类似随机 Mac 的机制，来提高隐私，以及安全性

iOS 8 以上的 MAC 地址随机应该只是在扫可用网和休眠状态下使用的。实际鉴权的时候用的是真实地址。
From iOS Security Guide: iOS uses a randomized Media Access Control (MAC) address when conducting Wi-Fi scans while it isn ’ t associated with a Wi-Fi network. These scans could be performed in order to find and connect a preferred Wi-Fi network or to assist Location Services for apps that use geofences, such as location-based reminders or fixing a location in Apple Maps. Note that Wi-Fi scans that happen while trying to connect to a preferred Wi-Fi Network aren ’ t randomized. iOS also uses a randomized MAC address when conducting enhanced Preferred Network Offload (ePNO) scans when a device isn ’ t associated with a Wi-Fi network or its processor is asleep. ePNO scans are run when a device uses Location Services for apps that use geofences, such as location-based reminders that determine whether the device is near a specific location. |

苹果会给 app 一个假 mac，这个功能估计关不掉，你硬件的真实 mac 是不能换的
