在大量使用后，为什么Finder会放慢速度并开始沙滩球运动？

我在OS X Yosemite 10.10.5上的Finder中遇到以下问题。

经过一段时间（通常大约10-15分钟）的大量工作之后，在目录中导航，移动/复制重命名文件后，它开始变得越来越慢，并且纺车开始出现，这使得使用它的整个过程变得太慢了。

我正在使用MacBook Pro 2009，配备来自Crucial的SSD，8 GB RAM。我具有重置权限，检查了磁盘上的文件结构，对SSD进行了磁盘实用程序/诊断软件可能的问题测试，删除了Finder首选项。该问题仅在最近才开始，过去没有此类问题。

如果我重新启动计算机，则Finder仍可以正常工作，直到我将开始再次进行大量使用。

如果有人想看看Finder旋转日志，我可以使用它们。

您最近是否安装了Adobe软件？如果是这样，我相信Creative Cloud会在Finder上安装“扩展程序”，这与它们的Core Sync功能有关（不完全确定那是什么）。请注意，我将“扩展”一词用引号引起来，因为Adobe实现此目的的方法纯属邪恶：通过将代码注入Finder进程中，这可以并且将改变Finder的行为方式。像您一样，我发现它可以在一段时间后停顿Finder。

我还没有找到一个永久性的解决方案，但这是我在启动时遵循的过程（它应该持续到下一次重启）。

1. 当Adobe Creative Cloud菜单的其他内容出现在屏幕右上角（在音量，日期等旁边）时，选择退出Creative Cloud。

2. 打开活动监视器，并找到以下后台进程： Creative Cloud.app（如果存在的话）， ，Adobe Desktop Service.app，Core Sync.app和AdobeIPCBroker.app*。

3. 使用活动监视器按以下顺序退出进程：

   1. Creative Cloud.app （如果正在运行）
   2. Adobe Desktop Service.app
   3. Core Sync.app
   4. AdobeIPCBroker.app

   如果您不遵循该命令，则其中一些可能会自动重新启动。

4. 然后退出并重新启动Finder。
