$ sysctl kern.maxfiles
kern.maxfiles = 3405
$ sudo sysctl -w kern.maxfiles=3500
kern.maxfiles: 3405 -> 3500
$ sysctl kern.maxfiles
kern.maxfiles = 3500
$ sysctl proc.$$.rlimit.descriptors.hard
proc.13239.rlimit.descriptors.hard = 3405
$ ulimit -H -n
3405
$ sudo sysctl -w proc.$$.rlimit.descriptors.hard=3450
proc.13239.rlimit.descriptors.hard: 3405 -> 3450
$ ulimit -H -n
3450
Notice I use root to increase the hard limit for my non-root process.
