错误信息：
Log path '/Users/robot/Library/Logs/AndroidStudio1.4' is inaccessible. If you have modified the 'idea.log.path' property please make sure it is correct, otherwise please re-install it.
如图
尝试如下做法：
rm -rfv ~/Library/Application\ Support/AndroidStudio*rm -rfv ~/Library/Preferences/AndroidStudio*rm -rfv ~/Library/Caches/AndroidStudio*rm -rfv ~/Library/Logs/AndroidStudio*rm -rfv ~/.AndroidStudio*把AndroidStudio相关的东西删除了，重新安装，无效。
最后解决办法：
> sudo mkdir ~/Library/Logs/AndroidStudio1.4
> chmod a+w ~/Library/Logs/AndroidStudio1.4/
粗暴的手动创建目录，并授权，成功启动！！
