这个问题我也遇到了，可能是Mac的Bug。就是VolumeName不能同名，不然会自动更新为下一个使用的Volume。

不好意思我SB了，是IHEP AC CN 202.38.128.58在我这是最好的DNS，但是Google DNS也很不错。

根据测试Google DNS是最好选择

必须得用Google的。别的都不干净。

重建图标缓存问题解决

原来是系统自带五笔输入法的问题，改用百度输入法了

奇怪，现在点x退出没quit unexpectedly了

用五笔也是这样吗？我没发现这个问题10.10.4

用popsearch扩展也可以做到

@jedihy 我说的有点错误，tcpdump是tcp，我要看的是http。

cd "/Volumes/Macintosh HD"
touch System/Library/Extensions
kextcache -prelinked-kernel System/Library/Caches/com.apple.kext.caches/Startup/kernelcache -K System/Library/Kernels/kernel System/Library/Extensions

后面的命令应该连起来，输我的试试

我刚试了，不开写入有60MB/s，开了写入有100MB/s，开好

@AKQJT tcpdump好像只能看ip和域名，好像url是tcp包的一部分，我用Packet Peeper抓包看到的是乱码，这是不是要用什么办法转换
