MacOS Sierra Upgrade - Java/Grails Development Environment Changes
As background, at work, we use Vagrant/VirtualBox to virtualize the development environment for most Java/Groovy developers. When I upgraded “recently” to MacOS Sierra we ran into a few less than straightforward issues; hopefully, this will help someone else out there.
Googling our monolith’s new found startup errors suggested that I needed to update my old versions to the latest of Vagrant 1.8.7 and VirtualBox 5.1.8. After which the Grails 2.x app started up without error. Below are the related search results that pointed me in that direction.
VirtualBox error on MacOS Sierra
Error - Failed to open a session for the virtual machine
There was an error while executing `VBoxManage`, a CLI used by Vagrant for controlling VirtualBox. The command and stderr is shown below.
However even after updating those, running our unit and integration tests were 10x slower than before the MacOS upgrade. We were seeing results similar to this StackOverflow entry:

In my case, I have added the following in /etc/hosts (partial):
127.0.0.1 localhost <computername>.local ::1 localhost <computername>.local
Replace <computername> with the name of your computer found @ ‘System Preferences -> Sharing -> Computer Name’
