如何用小牛队的替补优胜美地图标？

在升级到优胜美地之前，我想从小牛队备份应用程序图标，因为新图标非常难看。

保留小牛队旧系统图标的完整副本的最佳方法是什么？

更新：

最后，我使用Yuki Yamashina的方法一个接一个地做。

按照@ ohho的回答，我写了一个快速的脚本，可以省去调整每个图标颜色的工作量。此脚本也处理Dropbox文件夹图标。您将需要安装imagemagick和xcode命令行实用程序。获得两者的最佳方法是安装自制软件然后运行

brew install imagemagick

这是脚本。我选择将饱和度降低-20％并调整色调以使颜色变得更绿，更蓝。

将其保存为'〜/ folder_colour_adjuster.sh'，然后运行

如何更改Yosemite系统图标的颜色：

// Go to /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources folder
// where system icons are located.
$ cd /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/

// Backup the icns file for generic folder icon.
$ sudo cp GenericFolderIcon.icns GenericFolderIcon.org.icns

// Move the icns file to your home folder and go there.
$ sudo mv GenericFolderIcon.icns ~/
$ cd ~/

// Change file owner (from root to user).
$ sudo chown [user name] GenericFolderIcon.icns

// Open GenericFolderIcon.icns in Finder, then Preview is launched.
// Choose "Tools" => "Adjust Colors..." (shift+⌘+C), and adjust image's color as you want.
// In the following image, Saturation is decreased.
// Note that GenericFolderIcon.icns contains 10 images, and you should edit all of them.
// Save the file (⌘+S).

// Locate the icns file to /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources folder.
$ cd /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/
$ sudo mv ~/GenericFolderIcon.icns ./

// Change file owner and group, and remove Extended Attributes.
$ sudo chown root GenericFolderIcon.icns
$ sudo chgrp wheel GenericFolderIcon.icns
$ sudo xattr -d com.apple.quarantine GenericFolderIcon.icns

// Clear the icon cache.
sudo find /private/var/folders/ -name com.apple.dock.iconcache -exec rm {} \;
sudo find /private/var/folders/ -name com.apple.iconservices -exec rm -rf {} \;

// Restart Mac.

有一个很好的免费应用程序可以更改图标，LiteIcon。

我可以告诉你，这很难自己做。

如果您要更换系统图标，例如文件夹，则它们位于：

/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/

如果要替换/ Applications下的应用程序图标，则必须单独完成。典型：

/Applications/AppName.app/Contents/Resources/AppName.icns

更换后，新图标将不会显示，直到重置图标缓存。在Mavericks中，重置LaunchServices会更新图标，但在Yosemite中，从我花费的时间开始，必须删除“iconcache”。

总而言之，需要耐心。
