Running echo "say hello" | at now+1
on macOS should enqueue a task to be executed one minute in the future: saying hello. Issuing say hello
works fine, as does echo "touch a-file" | at now+1
, but the combination does not.
I believe that the runtime environment on which launchd
executes atrun
(the at
daemon) is restricted and cannot complete the speech synthesis instructed by say
. However, I cannot easily determine if this is the case.
What is the problem?
echo say hello | at next minute
respondsOpen speech channel failed: -915
. But I'm not sure what to do about that.
