virtualbox.org

Hi:

I'm running VB 4.2.18 on my Mac mini with OS X Mountain Lion. Runs without a glitch. I'm planning to upgrade my Mac to Mavericks. Are there any compatibility issues on Virtual Box with the latest Mac OS, that you know of?. If there are, I will wait until they are resolved. Thanks.

check out Virtualbox fails to run.. kernel driver not loaded

But, last I knew, VB v4.3 (fixes the above problem) is not properly signed for Mavericks
and so must tell OS X to accept from Anywhere in SysPrefs.
Doing Ctlr-Open does not make it. If you watch carefully, lots wont get installed
