1.安装 libimobiledevice 时就提示 warning：系统过高，没有提供支持，不知道是不是这个原因

Warning: You are using OS X 10.12.
We do not provide support for this pre-release version.
You may encounter build failures or other breakages.
Please create pull-requests instead of filing issues.

2. appium app 启动 inspector 的报错日志, 提示 Xcode 版本过高不支持，是不是真的是这个原因呢？如果是,有更新支持的时间计划吗？

具体日志信息如下:
