关于“xx.xx已被OS X使用，无法打开”的问题

Mac电脑上的文件拷贝到移动硬盘，有时候会出现“xx.xx已被OS X使用，无法打开”的问题。

解决办法：

1、打开终端

2、在终端里输入 xattr -l ，然后把出问题的文件拖动到 "xattr -l 后面",回车；

localhost:~ Kingdev$ xattr -l

localhost:~ Kingdev$ xattr -l /Users/liuxianzhi/Desktop/屏幕快照\ 2016-03-12\ 21.37.25.png

3、然后，第一行会有 com.apple.FinderInfo 这串字符。复制这串字符，回车；

    localhost:~ Kingdev$ xattr -l /Users/liuxianzhi/Desktop/屏幕快照\ 2016-03-12\ 21.37.25.png
    com.apple.FinderInfo:

4、接下来，输入新的命令 xattr -d com.apple.FinderInfo 再把问题文件拖进去，问题就解决了

localhost:~ Kingdev$ xattr -d com.apple.FinderInfo /Users/liuxianzhi/Desktop/屏幕快照\ 2016-03-12\ 21.37.25.png
