This release introduces MacOS guest support, but the license agreement for MacOS states that it must not be run on non-Apple hardware. From the VirtualBox manual:<p><i>"Mac OS X verifies whether it is running on Apple hardware, ...these restrictions are not circumvented by VirtualBox and continue to apply."</i><p>Wonder how long until someone patches the source to remove this check. A guest OS shouldn't be able to snoop and find out what kind of hardware the host OS is running on...smells like a hack.
