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。

我目前使用MondoMouse，即使有它的怪癖，没有它我也无法使用我的mac。他们有免费试用，我会推荐给每个人。

Steve Yegge不久前写了一篇关于这个问题的文章，他试图写一个合适的扩展，但失败了。从那以后，我试图为OS X找到聚焦跟随鼠标的应用程序，也失败了。

如果有人感兴趣的话，这里有一个多监视器自动对焦的玩具级实现:https://bitbucket.org/sivann/mac-screenfocus/src/master/

它大部分工作，但不能处理同一应用程序在不同显示器的多个窗口。如果你将鼠标移到另一个显示器上，会将焦点移到上一个应用程序上。

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。

不幸的是，CodeTek虚拟桌面专业不再开发，该公司似乎已经退出业务几年前。

历史参考:http://www.codetek.com/ctvd/(不适用于新的OS X版本!)

历史回顾:http://www.osnews.com/story/6144

使用CodeTek Virtual Desktop Pro，你可以获得焦点-跟随-鼠标，并禁用自动上升，它也有一个虚拟桌面的寻呼机——类似于Fvwm在Linux上的工作方式。它运行得非常完美——这是我买过的最好的软件。 它与所有应用程序都一致，切换应用程序，将窗口移动到不同的工作区，以及导航工作区都比最新的OS X版本[10.6,10.7,10.8]要容易得多。

不幸的是，随着Mac OS X 10.5 VirtualDesktop Pro停止工作，看起来苹果积极确保CodeTek不会继续在它上面工作。

令人遗憾的是，苹果粉碎了CodeTek和它的产品——虚拟桌面专业版(Virtual Desktop Pro)真的比OS X当前实现的工作区更好。它的工作原理基本上就像LINUX上的Fvwm——超快的导航——没有不必要的点击或鼠标手势……

看到苹果规定窗口管理器(Finder)的行为，似乎不再允许第三方替换Finder，我很难过。
