【问题描述】：
几天前，“时间分析器”停止工作。其他工具仍然有效...核心动画、分配等。时间分析器只是一个空白屏幕。没有显示函数调用，没有图表，什么都没有。多个项目的结果相同。
我刚刚重新安装了 Xcode（通过自身）。同样的问题。我找不到任何可以为 Instruments 删除的首选项文件。我真的，真的需要这个工作。我真的没有时间重新安装整个操作系统。
帮助
编辑：删除 com.apple.dt.instruments.plist 不会改变任何内容。从仪器（下）的控制台中找到这些日志。看起来发生了一些有趣的事情，可能值得向 Apple 提交一个错误。现在的问题是 - 我如何将仪器的状态重置回应有的状态？

Set the NSUserDefault NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES to have -[NSWindow visualizeConstraints:] automatically called when this happens. And/or, break on objc_exception_throw to catch this in the debugger.
