Mac 上为什么 Homestead 安装到 Vagrant 以后，在本地 ping192.168.10.10ping 不通？文件夹也没共享至 Vagrant 上？

我是mac os环境，请问为什么按照文档中安装好homestead以后，homestead ssh后，在/home/vagrant中没有出现共享文件夹，并且在本地ping192.168.10.10也ping不通，后来修改Vagrantfile文件里面的config.network和config.ip后重启vagrant才出现共享文件夹，并且也能ping的通，但是即便这样能ping的通，本地hosts配置的192.168.10.10 homestead.app后，浏览器输入homestead.app还是连接不上服务器。请大神指教为什么？第一次不怎么会用markdown，望见谅。在线等大神，着急～
下面是homestead up的信息，可以看到共享文件夹就一个，还不是有项目代码的那个文件夹
