Mac update 2018-001 - Failed to connect to the engine

after installing security patch 2018-001 in macOS high sierra 10.13.4 Hamachi won't connect...."fails to connect to the engine".

I've tried uninstalling and installing again with no positive results.

Other issues noted before such as allowing the developer in the mac settings, don't work either, I believe this is a totally new issue caused by the mac update and there is no way to revert it.

 

please help....
