执行 ideviceinfo -u 和 ideviceinstall -l时，报错

ERROR: Could not connect to lockdownd

解决办法

先断开所有连接PC的iOS设备

执行

brew uninstall libimobiledevicebrew install --HEAD libimobiledevicebrew link --overwrite libimobiledevicebrew install --HEAD ideviceinstallerbrew link --overwrite ideviceinstallersudo rm -rf /var/db/lockdown/*

重新插上iOS设备，待“是否信任计算机”窗口弹出，点击“信任”

再执行 sudo chmod -R 777 /var/db/lockdown/
