I've followed the steps to make coredump enable in my machine (mainly by setting ulimit -c unlimited and allow write permissions for all a+x in /cores folder).

However, it seems like It doesn't work while SIP is enabled in my machine csrutil enable (I tried sending kill -11 to /bin/sleep running process). When SIP is disabled however, it works just fine.

Does SIP prevent coredump on all processes or only apple signed one ?
