dyld: Library not loaded: /usr/lib/libcrypto.35.dylib
Referenced from: /System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice
原因是升级iTunes时MobileDevice依赖libcrypto.35.dylib，iTunes 12.8以前是不依赖的，libcrypto.35.dylib这个库又依赖其他的库，版本不一致

解决方法：
把/System/Library/PrivateFrameworks/MobileDevice.framework这个文件夹删除
再把高版本的iTunes卸载，装低版本的iTunes， 我这边装的是12.7.3的版本，安装过程中，会装上/System/Library/PrivateFrameworks/MobileDevice.framework这个模块
