Amethyst支持此特性。它可以很容易地安装与酿造安装紫水晶。

下面是我使用的配置文件。它关闭了所有的功能，除了焦点跟随鼠标。保存到~/.amethyst。

菜单问题是传统的焦点跟随鼠标无法工作的唯一原因。

这里有一个替代方案:在键盘上按下一个键之前不要改变焦点。这将覆盖95%的焦点跟踪鼠标用例，并将使这个老的脾气暴躁的X用户非常高兴。我不知道有多少次我在Chrome中浏览网页，按下Command-T键打开一个新标签，却发现这个标签在终端中打开了。如果我的大脑在使用Mac的8个月里还没有注意到这一点，那它永远也不会注意到。

聚焦鼠标并不是一个特别适合OS X的输入法，因为它的菜单栏被设计在屏幕的顶部。当您将鼠标移出应用程序窗口以进入菜单时，如果它在此过程中穿过任何其他应用程序的窗口，菜单将发生变化。

所以是的，在回复dreeves的评论时，它对终端(或桌面上任何其他单一应用程序)工作得非常好，因为它只会影响终端窗口，所以当你切换窗口时，菜单永远不会改变。它适用于X11，因为X11应用程序通常将它们的菜单栏嵌入在窗口中，所以你不必离开窗口就可以访问它们。

当然，您可以通过在焦点更改和/或菜单切换之前引入人为延迟来解决菜单更改问题，但它永远不会像在其他桌面上那样工作。

虽然这还远远不是一个完整的解决方案，但OSX(10.11)中内置了两个方便的操作:

⌃-click (control-option-click)—切换焦点而不抬高窗口

⌘-click (command-click) -在窗口中单击而不切换焦点

不确定这些快捷方式是什么时候引入的，因为我在任何地方都找不到关于它们的文章。

有趣的是，Leopard在默认情况下启用了一种焦点跟随鼠标(无自动提升)功能。滚轮在非聚焦窗口中工作。

你不可能真的做得很好，因为Mac界面的设计根本没有考虑到焦点跟随鼠标(有或没有自动上升)。我怀疑这种情况在短时间内不会改变，除非它改变，否则每个试图实现焦点跟随鼠标的人都会遇到同样的障碍，并以不满意的结果结束(对于那些想要这样做的人来说)。

所以，是的，你想要这个是疯狂的——但出于技术原因。习惯按自己的方式使用Mac，我相信当你找到新的高效的工作方式时，你强迫它像你过去使用的任何X11东西那样工作的愿望会逐渐消退。
