We have a problem with netbiosd on our University Network (thousands of users) and netbiosd broadcasts, that Networking aren't able to resolve...

On most our Mac's it ends up chewing up 1-50% CPU usage all day, everyday...

Prior to 10.12.4, we just unloaded the LaunchDaemon, as below:

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.netbiosd.plist

/System/Library/LaunchDaemons/com.apple.netbiosd.plist: Operation not permitted while System Integrity Protection is engaged

As of 10.12.4 it won't let us without disabling SIP and keeping it off, which isn't ideal.

Is there a supported way to unload netbiosd going forward? Managed Preference? Creating a conf file? .plist change somewhere else?

Thanks,

Matt

You might have better luck asking this question over in Apple Support Communities, run by AppleCare, where you’re more likely to find folks with experience with NetBIOS on large networks.
