I am trying to install VirtualBox on my Mac OS Sierra 10.12.5 which is spitting out an ambiguous error that I can't find a definitive solution for online.
I do remember having installed VirtualBox before and an uninstalled it so I went ahead and removed all traces of any previous installation, rebooted, checked activity monitor and it still doesn't work.
Here's the installer log:

Code: Select all

Any help is greatly appreciated.

I have the same problem. VirtualBox installs but I can not boot any virtual machine.

How is this the same problem? My problem is that I cannot get Virtualbox to install at all.
