Welcome to the VirtualBox uninstaller script. This is the terminal log of what happened:

I ran the uninstaller in terminal using this command - sudo /bin/sh VirtualBox_Uninstall.tool Intially this command did not work, but adding the /bin/sh to the command line instruction made it work OK eventually.

I moved the uninstaller script to my home folder (~).

In safe mode I then opened safari and downloaded the VirtualBox uninstaller from here.

But it did get me to a working desktop eventually.

on my system this resulted in a very long pause in the resart sequence, and then once the restart had begun the completion of the Beta 6 install restarted, and this also took a long time (and required me to re-log-in twice).

I restarted my system in safe mode - hold down the shift key during the boot sequence.I found an easier way to fix this issue on my system. įinding a fix for this issue is not easy - and several have resorted to fully restoring a working OS X 10.11 beta 5 or earlier system, uninstalling the VirtualBox app using an uninstaller, and then trying to migrate to Beta 6 again. There are other threads that have appeared with discussions of these issues - e.g.

It seems that if you have an old (not sure how old, but not current) version of VirtualBox on your OS X 10.11 beta <6, you'll not be able to complete the installation of OS X 10.11 beta 6 due to a kext induced crash during the late stages of the install migration.
