出于原因，我一直任务将Mac Box升级到El Capitan。El Capitan与最新版本的Xcode一起运行。
我遵循以下步骤处理新的sip：
如何在Mac OS X El Capitan中安装自制
如何在OS X El Capitan中的Homebrew上解决权限问题？
我将所有这些东西都恢复了顺序（或者至少似乎是这样），但是由于无法访问config.xml文件，盒子的詹金斯似乎已经关闭。认为这是更多的许可问题（这就是为什么我在两个引用的链接中执行了步骤），我发现此帖子重置Jenkins配置命令行，我确认了Jenkins Wiki上的步骤，我执行了所需的步骤：
1)Stop Jenkins (the easiest way to do this is to kill the servlet container.)
2)Go to $JENKINS_HOME in the file system and find config.xml file.
3)Open this file in the editor.
4)Look for the <useSecurity>true</useSecurity> element in this file.
5)Replace true with false
6)Remove the elements authorizationStrategy and securityRealm
7)Start Jenkins
但是当我去詹金斯时，我仍然无法访问/.../config.xml
正如我所说的，我是整个过程的新手（实际上与Mac打交道），所以有人比我对发生的事情更有经验吗？
这是参考的堆叠：

我还尝试了此jira的解决方案：https：//issues.jenkins-ci.org/browse/jenkins-9774仍然没有运气。
事实证明这是一个Java版本管理问题。El Capitan更新后，它促使我重新安装Java，默认安装当然是Java 8.返回Java 7并安装了Maven 3.0.2，所有内容都启动并运行。
