macos - 创建后 10 秒从 OSX 桌面莫名其妙地删除 PNG 文件

Question

这个奇怪的事情刚刚开始在我的 Mac 上发生，我不明白。复制到 ~/Desktop 的新 .png 文件会在 10 秒内被删除。

.txt 文件不会发生这种情况。实际上是文本文件的 .png 文件不会发生这种情况。实际上是 .png 文件（按内容）的 .txt 或 .bin 文件确实会发生这种情况。复制到桌面子文件夹中的任何文件都不会发生这种情况。

桌面已链接到 iCloud，但一直如此。我没有更改任何与 iCloud 相关的设置。我在同一台机器上的不同帐户中安装了 DropBox，但该帐户未登录且 DropBox 未运行。

谁能解释发生了什么以及为什么它才开始发生？

这是测试脚本：

#!/bin/bash
do_it() { 
    date; 
    cp $1 Desktop/; 
    count=15; 
    while test $count -gt 0 && sleep 1; do 
        let count=count-1; 
        echo "$(date) $(ls Desktop/$(basename $1))"; 
    done; 
}

run() {
    for n in desktop.png desktop.txt desktop.zero.bin desktop-png.bin desktop-png.txt; do
        do_it Documents/$n
    done;
}

run

这是输出 - 注意包含 .png 内容的文件是如何被移动或删除的，但不包含 PNG 的文本文件和二进制文件不会被移动或删除。

更新：感谢Joseph，我安装了这个简单的审计工具，发现它是重命名文件的“鸟”过程。这个“鸟”进程与 iCloud 相关联，当我查看 iCloud 上恢复的文件页面时，我可以看到正在消失的文件。

所以，下一个问题是：为什么 iCloud 会这样做，我如何告诉它停止？
