Codetek有一款产品可以做到这一点，但他们从未为Leopard或更高版本发布过版本。

MondoMouse可以做焦点跟踪鼠标，但不能自动提升。 即使是焦点跟随鼠标也坏了。 例如，它不能很好地使用命令-标签(如果你命令-标签到一个新应用程序，并且不碰鼠标，那么它不应该将焦点切换回鼠标指针所处的位置——我非常确定我所见过的Linux中的每个实现都能做到这一点，但MondoMouse没有)。

你可以只在终端窗口中启用焦点跟随鼠标(没有自动升起)(只需在终端中执行以下命令):

defaults write com.apple.Terminal FocusFollowsMouse -string YES

同样，对于X11窗口:

defaults write org.x.X11 wm_ffm -bool true 

(对于10.5.5之前的mac版本，这是:

defaults write com.apple.x11 wm_ffm true

)

我不知道还有其他应用程序支持它。

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。

给DwellClick一个尝试。虽然这不是它的预期目的，但自动单击行为有一个类似于自动提高或焦点跟随鼠标的副作用。

就我个人而言，我只在光标移动停止后使用左键点击的功能，但也有修改器点击和窗口拖动辅助功能，这非常方便。

在浏览网页时，这也有点令人沮丧，因为你要么想要禁用应用程序，要么更注意光标停留在哪里(例如，不要停留在任何你不想激活的链接或按钮上)。

尝试了这些选项后，我的Command-Tab开始表现得很奇怪。以下是它如何再次关注应用程序的解决方案:

之前的一个特性，即终端的窗口焦点随着鼠标移动而改变的能力，在10.6中被打破，导致Command-Tab不能正确地转移窗口焦点。要解决这个问题，只需在终端中粘贴以下命令:

默认写com.apple.Terminal FocusFollowsMouse -string否

然后重新启动终端。

在MacOS Mojave上测试MondoMouse (https://www.atomicbird.com/about/mac-apps)。对我来说似乎很有效!

要安装预装面板，将会有一个通知“为辅助设备启用访问”，不再驻留在系统首选项>可访问性中。你必须在安全与隐私>可访问>隐私中设置它

在你打开的每个应用程序中都会有几个关于允许MondoMouse的警告，但一旦设置它就可以正常工作了!真是松了一口气。

So I decided to improve again on the work I did on the MouseFocus.app which still had some flaws. Those are fixed now. I renamed the whole thing to "AutoRaise" to better reflect what this tool does: When you hover a window it will be raised to the front (with a delay of your choosing) and gets the focus. The tool can be downloaded here. To use it, copy it to your /Applications/ folder making sure it is executable (chmod 700 AutoRaise). Then double click it from within Finder. To quickly toggle it on/off you can use the applescript below and paste it into an automator service workflow. Then bind the created service to a keyboard shortcut via System Preferences|Keyboard|Shortcuts.

更新(29-03-2017):AutoRaise二进制文件已经更新。如果命令行上没有指定delay，它现在也会在同一个主文件夹中查找autorrise .delay文件。这在使用下面的applescript时特别有用，因为“启动应用程序”不支持命令行参数。延迟应该以50ms 20ms为单位指定。例如，在一个终端上执行'echo 1 > ~/AutoRaise.delay'命令，指定延时为20ms。

on run {input, parameters}
    tell application "Finder"
        if exists of application process "AutoRaise" then
            quit application "/Applications/AutoRaise"
            display notification "AutoRaise Stopped"
        else
            launch application "/Applications/AutoRaise"
            display notification "AutoRaise Started"
        end if
    end tell
    return input
end run

更新(18-04-2019):来源https://github.com/sbmpost/AutoRaise

更新(05-06-2020):默认延迟时间被设置为2，轮询时间被缩短。这些设置可以防止快速移动鼠标(例如到达顶部菜单)时意外地弹出窗口。同时一个扭曲鼠标功能已经添加和内存泄漏已被修复。欲了解更多细节，请参阅README
