旁注用户 B 设置为 admin

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？

Answer 1

我找到了一个似乎有效的替代方法...

如果我加上

sudo -u username 在 osascript -e 命令之前，然后就可以了。

例子

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

从阅读内容来看，苹果似乎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，添加如下命令 sudo -u username

osascript set volume 无法通过 ssh 工作

osascript set volume isn't working via ssh

ssh

volume

set

osascript
