VirtualBox

Trying to upgrade VirtualBox to 4.3.12-93733 (from 4.3.10) on OS X 10.9.3 fails with the message:

"The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance."

MacBook Pro Retina w/ lots of memory and disk.

I tried uninstalling without luck. It failed with:

unloading org.virtualbox.kext.VBoxUSB
(kernel) Can't unload kext org.virtualbox.kext.VBoxUSB; classes have instances:
(kernel) Kext org.virtualbox.kext.VBoxUSB class org_virtualbox_VBoxUSB has 1 instance.
Failed to unload org.virtualbox.kext.VBoxUSB - (libkern/kext) kext is in use or retained (cannot unload).
An error occurred durning 'sudo /sbin/kextunload -m org.virtualbox.kext.VBoxUSB', there should be a message above. (rc=3)

Failed to unload one or more KEXTs, please reboot the machine to complete the uninstall.

I also tried a suggested:

Code: Select all

% sudo /Library/Application\ Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh restart

but got:

just download the latest version. with VirtualBox closed, run the VirtualBox_Uninstall.tool. Install the new version.
