virtualbox.org

I keep on getting the same error Kernel driver not installed (rc=-1908). If I reinstall virtual box it will work, for a while then I will eventually get the error again. Has anyone else had this problem?

Yep. Same error

I was also getting a permissions error on my IMAC start up in /library/startupitems/virtualbox/

Solution was to repair permissions using Disk Utility - Repair Disk Permissions on my C drive.

Restart

Hope this helps.
