High sierra Firewall logs

Why is there no Firewall logs in High sierra?


Looking at the Apple forum posts this problem existed in the previous O.S. and still has not been corrected. Perhaps Apple should hold off on new versions and fix some major problems before continuing to a new O.S.

MacBook Pro, macOS High Sierra (10.13.5)

You asked Why is there no Firewall logs in High sierra which cannot be answered because it is a false assertion. Firewall logging has been improved and needs to be enabled and configured for whatever specific purpose you require.


Logging in macOS Sierra and HS is explained in man log. For help regarding the application firewall specifically, use /usr/libexec/ApplicationFirewall/socketfilterfw -h


Firewall logging options are set with --setloggingopt


In addition to being much more efficient it provides far greater detail than was available in previous macOS versions.

Here is some simple pictures to show you logs exist for all clients and that no user should go through a man pages which is a help information for something that already exists for L2TP VPN built in client. If it exists for one client it should exist for all VPN clients.

Notice how the use verbose logging exists for L2TP? Why should logs exist for L2TP and not for IKE client?

When I was using Yosemite I could see connections times disconnect times and few other items. I cannot find any logs on high sierra.

How do I view connection times, disconnect times, protocol used? This issue did not exist since Sierra I understand.
