VirtualBox

fixing a bug Kernel Driver Not Installed (rc=-1908) Error on Mac

In the terminal type:

sudo kextload -b org.virtualbox.kext.VBoxDrv

sudo kextload -b org.virtualbox.kext.VBoxNetFlt

sudo kextload -b org.virtualbox.kext.VBoxNetAdp

sudo kextload -b org.virtualbox.kext.VBoxUSB

Now you can run the VM in the ritual box. Need to know that you probably need to follow the same steps every time you restart your MAC.
