我有一台安装了 macOs Big Sur 的 Macbook Air（M1，2020）。我刚刚清除了设备并重新安装了操作系统。我想做的是更改、删除或添加接口，但我做不到。每次我尝试更改时ifconfig: ioctl (SIOCDIFADDR): Can't assign requested address都会出现一些问题。
我已经尝试过了
sudo ifconfig [interface] down
sudo route flush
sudo ifconfig [interface] up
沒有改變任何内容。
这是我的ifconfig输出：

有什么建议我可以尝试避免这个错误或我的网络发生了什么？
答案1
目前尚不清楚您发出了哪些命令导致了错误。
就我而言，我在尝试使用 更改 macOS 14.3.1 (Sonoma) 上的 Wi-Fi MAC 地址时看到了此错误。如果 Wi-Fi 接口已关闭或已连接到网络，sudo ifconfig en0 ether xx:xx:xx:xx:xx:xx则会导致此错误。ioctl (SIOCAIFADDR): Can't assign requested address
解决方案是保持 Wi-Fi 开启，但断开与任何网络的连接。断开接口后，ifconfig成功运行，我能够更改 MAC 地址。此时，我能够重新连接到所需的网络。
