I am tailing the system.log on a mac:

tail -f -n 0 /var/log/system.log 

but I can't figure out how to write to this log. It does seem to be the main log on the machine. I tried:

logger foobar # didn't work syslog -s -l error "message to send" # didn't work 

anyone know how to write to the system.log on a Mac?

update:

if I run: log stream

and then use:

logger -is -t krypted "Hello L" 

it will show up in the stream, but not in /var/log/system.log. weird.
