Hi @Dickerson

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:

1. open system preferences > users & groups > login items
2. Logmein hamachi showed a yellow yeild sign and "unknown"
3. select logmein hamachi and press the "-" below to remove from startup items.
4. restart computer. hamachi opens and connects fine.

hopefully this helps others as well.
