我在Tahoe中针对cron的文件访问解决方案
假设你想在一个定时任务（cron job）中访问一个文件夹。也许它在另一个驱动器上，或者是一个Dropbox文件夹。哦不，你不能！不允许！这不是权限问题，而是全盘访问的保管链！
你可能会说，没问题，我会在这个充满系统偏好的便捷图形界面中给定时任务（cron）提供全盘访问权限，那个窗口角落圆润得很。简而言之，你无法给定时任务（cron）提供全盘访问权限。你可以尝试一次又一次，但它就是不行。你无法给许多其他极其有用的二进制文件提供全盘访问权限，即使你希望它们能够拥有。为了上帝的名义，你甚至无法给sshd提供全盘访问权限。你能做的就是找到那个隐藏的设置：在“系统偏好设置”中依次选择“共享” > “远程登录” > （信息按钮） > “允许远程用户全盘访问”。这非常讽刺，因为它允许<i>任何通过SSH连接的人获得全盘访问权限</i>。
呵呵呵。
今晚我解决了苹果公司创建的那个愚蠢系统，它阻止我通过定时任务（cron job）访问我自己的机器：更改那个设置，现在只需让你的定时任务通过SSH连接到本地（localhost），一切就能完美运行了 ;)

Suppose you want to access a folder in a cron job. Maybe it's on another drive, maybe it's a Dropbox folder. Oh no, you can't! Not allowed! It's not a permissions issue, it's the chain of custody for full disk access!<p>No problem you say, I'll go and give cron full disk access in this handy GUI full of system preferences with the nice ultra-round window corners. TL;DR, you can't give full disk access to cron. You can try, over and over, but it will not work. You can't give full disk access to lots of other extremely useful binaries that should be allowed to have it if you want them to. You can't even give it to sshd for the love of God. About all you can do is find the buried preference in General > Sharing > Remote Login > (info button) > "Allow Full Disk Access for Remote Users". Which, rather ironically, lets <i>anyone who connects via SSH get full disk access</i>.<p>Heheheh.<p>Tonight I fixed the inane system Apple created that prevents me from accessing my own machine with cron jobs: Change that setting, now just have your cron jobs ssh into localhost and everything works perfectly ;)
