恶作剧
早上同事用QQ发了一段文字给我，内容为如下： 玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉王玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉玉 当我点开这条QQ消息的时候，QQ瞬间就崩溃了！我还不知道怎么回事，重新打开了QQ查看刚才发过来的这条消息，QQ再次崩溃。怎么QQ崩溃啦我整个人都不好了，233…… 我上网查了一下，发现很多人都遇到了类似问题，原来这是一个新的Mac文字漏洞。
探索
以下是有人在知乎上提的问题：
从浏览次数和关注人数来看，说明很多人都被调戏了！QQ的崩溃信息如下：

分析
从崩溃信息可以看到是在NSTextCheckingOperationQueue线程中崩溃的，这是一个执行文本检查的线程。 其实之前苹果就出过几次类似问题，比如”Fill:///“崩溃问题。都是DataDectorsCore.framework这个framework的问题， 这个库的主要作用是自带的拼写检测和特殊格式的信息（比如URL、电话号码、时间等）匹配都会触发 DataDectorsCore.framework。 我查找了”Fill:///“崩溃问题的解决方案，于是也尝试了同样的方案解决这个问题，果然不出所料的不再崩溃了！
Debug
解决崩溃问题的方法就是： 在终端运行以下两条命令：
sudo mv -v /System/Library/PrivateFrameworks/DataDetectorsCore.framework/Versions/A/Resources/com.apple.datadetectorscore.cache.urlifier.system /System/Library/PrivateFrameworks/DataDetectorsCore.framework/Versions/A/Resources/com.apple.datadetectorscore.cache.urlifier.system.backup
sudo mv -v /System/Library/PrivateFrameworks/DataDetectorsCore.framework/Versions/A/Resources/com.apple.datadetectorscore.cache.full.asia.system /System/Library/PrivateFrameworks/DataDetectorsCore.framework/Versions/A/Resources/com.apple.datadetectorscore.cache.full.asia.system.backup
