I recently reloaded my laptop and upgraded it to Sierra. As Apple continues to tighten down security measures, more and more programs are having trouble installing properly (or living through the upgrade process).
The problem I experienced was with installing VMWare Fusion: particularly with calling
vagrant up. In doing so, I received the following cryptic error: “Error occurred: The file which defines networking interfaces for VMware Fusion could not be found. Please verify Fusion is installed properly and try again. If this problem persists, please contact support.” Additionally, when I tried to create a dummy VM in VMWare Fusion, I also received a cryptic “Internal error” message.
I found that the file
/Library/Preferences/VMware Fusion/networking was non-existent. Since there was another machine that I use that works as expected, I copied the
networking file over to my laptop. Vagrant booted the machine just like it was supposed to.
For your (and my) reference, here are the contents of the file:
