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.
The error "Failed to connect to engine" is caused by the LogMeIn Hamachi Tunneling Engine either failing to start, being in an error state, or being blocked by anti-virus software. If your anti-virus software is reporting/blocking Hamachi-2-ui.exe, you will need to add an exclusion for the Hamachi-2-ui.exe program. Please consult your anti-virus software documentation for assistance with adding an exclusion to the allowed list.
On Mac please try the steps posted by @cbrough
Our solution was:
hopefully this helps others as well.
Is there any timeline for supporting the new Apple ARM Macs. We got our first one this week, but we are unable to run Hamachi on it. Not a deal breaker yet, but this will be a requirement for us in the next 6-10 months.
