IIRC, one process cannot send a Unix signal to another one.
At least, not any more, and not without special privileges.
But would it be possible for a user to send a SIGUSR1 (using 'kill -30 <pid>'
on the command line) to a process they own?
I couldn't find information about that.
In fact, in the developer docs i couldn't find any info about Unix signals,
what is possible or not under the new security regime in macOS.
(I can't remember where i read about the new limitations regarding signals
under the new security regime.)
Any info will be highly appreciated.
Best regards, Gabriel
