+ <td>When set to <tt>true</tt> or a synonym, enable the CPU's VMX bit and lock the MSR. This configuration is necessary for some hypervisors (notably Microsoft's Hyper-V) to function properly. Activating it on other CPUs will, at best, have no effect, and could conceivably crash the computer, so enable it at your own risk! If your firmware supports activating these features, you should use it instead; this option is provided for users whose firmware does not provide this functionality. (Many Macs lack this configurability, for instance.) The default is <tt>false</tt>.</td>

+ <td>On some Macs, this option causes rEFInd to tell the firmware that the specified version of OS X is being launched, even when another OS is selected. The effect is that the firmware may initialize hardware differently, which may have beneficial (or detrimental) results. If your Mac's video output isn't working normally, this option may help. On the other hand, keyboards and mice are known to sometimes stop functioning if this option is used, so you shouldn't use it unnecessarily. This option has no effect on non-Apple hardware. The default is to not use this feature.</td>
