今天pycharm启动不了，点击pycharm图标没反应，查了下系统日志/var/log/system.log看到如下报错
objc[51527]: Class JavaLaunchHelper is implemented in both /Applications/PyCharm.app/Contents/jre/jdk/Contents/MacOS/libjli.dylib (0x 10c4a1480) and /Applications/PyCharm.app/Contents/jre/jdk/Contents/Home/jre/lib/libinstrument.dylib (0x10cff74e0). One of the two will be used. Which one is undefined.
尝试过以下方法都不成功：
1. 重装pycharm
2. 换最新版的pycharm
3. 重启系统
4. 重装jdk
均以失败告终.......
后来找了下用户目录下的文件，找到了pycharm的配置。
在这个目录下：/Users/YourUserName/Library/Preferences/PyCharm2016.2/
删除截图的几个文件后恢复。
