Is there a simple way for one process to send a single signal to another process? Both processes are my programs, one is a regular app, the other a menu bar item. Both are launched by the same user.
In the old unix days, I would have used kill(2) and send a SIGUSR1 , but as far as I understand, this is no longer possible. (At least, not without privilege elevation, which seems too complicated.) All hints and ideas will be appreciated! Best regards, Gabriel
