不是权限问题，因为我 automation 运行写脚本都没有问题。

1、 log 和代码使用代码块：

代码块

2、 不要只给你觉得有问题的少数几条 Log ，给出完整的 log（接收到 create session 请求到返回 fail 信息）

第一次发帖 下次格式一定改

@smallboy 请问这个问题你解决了吗。我现在也陷入同样的困境

同进一个坑

app 是用模拟器的 sdk 打的包吗？

这个问题解决了吗？我也遇到这个问题了

感觉碰到这个问题的人很多啊~

如果证书没有问题的话，把 appium 的超时时间改大点试试。

遇到这种问题，先做一件事情。使用 xcode 的 instruments 的 UIAutomation 直接打开应用，开始 record，然后播放下，看看应用本身是否能自动化。

前一阵子 mac 坏了 运维带去修 重新做了系统，今天刚刚做好 又重新安装一遍 现在又出现了新的问题。。。

重装下 libimobiledevice 试试。

@chenhengjie123 重装过了 现在又发现一个问题 UIAutomation 链接真机进行录制 真机会卡死 但是在虚拟机上面运行就正常。 Xcode 版本是 7.0 真机系统版本是 8.3 您有遇到过这样的情况么？

Xcode 7.0 上没试过录制。
卡死的话报啥错？

怎么重装 libimobiledevice，
