这是我的情况。

用户 A当前登录计算机A。

用户 B通过 ssh登录到计算机 A。

用户 B通过终端运行 osascript ( osascript -e 'set volume 0')

这是我的错误日志：

旁注 用户 B 设置为管理员

曾几何时，我记得以前执行过这种情况，没有任何错误。不确定这是否是具有特权的ARD 设置？

我找到了一个似乎可行的替代方案......

如果我添加

sudo -u username在osascript -e命令之前，它可以工作。

例子

sudo -u username osascript -e 'set volume 0'

从阅读的内容来看，似乎苹果不允许用户在另一个用户登录时通过 ssh 会话打开应用程序。必须以当前用户身份登录才能运行osascripts，否则，添加以下命令sudo -u username
