Syslog Wake Reason not working

[Donga120]

My Macbook has dreadful sleeping battery drain. Not sure if its due to MacOS or something is waking my laptop all the time. When I run the "syslog | grep -i "Wake reason"" command in terminal I get this error:

NOTE: Most system logs have moved to a new logging system. See log(1) for more information.

I have googled this and cant find anything so presumably it has changed for MacOS and with it being a beta its not very popular. Anyone know how else to see what has been waking my computer or the new command?

Thanks

This works in EC -

syslog |grep -i "Wake"

You're welcome. There's always Console (if it's in the beta).
