Class NPUtilities implemented twice

[Jacouille341]

On a ProBook 4740s, boot with Clover, I rum Yo from 2015.
Now I try to install High Sierra staying in HFS+ on a separate partition.
Installation runs fine, but at first restart I get fast reboot.
I use verbose and safe boot option to observe.
Looking at system.log I can find explanations:
Class NPUtilities and Class NSPConnectionInfo are implemented twice.
see systemlog
Class NPUtilities is implemented in both /System/Library/PrivateFrameworks/NetworkServiceProxy.framework/Versions/A/NetworkServiceProxy (0x7fff8c548c78) and /System/Library/UserEventPlugins/com.apple.netsvcproxy.plugin/Contents/MacOS/com.apple.netsvcproxy (0x100dbc6a0). One of the two will be used. Which one is undefined.

...... Class NSPConnectionInfo is implemented in both /System/Library/PrivateFrameworks/NetworkServiceProxy.framework/Versions/A/NetworkServiceProxy (0x7fff8c548d40) and /System/Library/UserEventPlugins/com.apple.netsvcproxy.plugin/Contents/MacOS/com.apple.netsvcproxy (0x100dbc790). One of the two will be used. Which one is undefined.

I did some search about that without success.
Could some expert help me ?
Thank you
