Question

这是我的情况。

用户A 目前已登录计算机A 。

用户B 通过ssh登录计算机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admin

曾几何时，我记得在没有任何错误之前执行这种情况。不确定这是否是具有权限的 ARD设置？

Answer 1

我找到了一个似乎有用的替代方案......

如果我添加

在sudo -u username命令之前

osascript -e，然后它就可以了。

示例

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

从阅读内容看来，当其他用户登录时，苹果似乎不允许用户通过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

osascript set volume无法通过ssh工作
