    If you see VMX entry then CPU supports Intel VT-x feature, but it still may be disabled.

  4. Please run Software Update from Apple to resolve this issue.

    Note: As article states, VT-x can be disabled due to an outdated firmware what's why we suggest running Software Update as firmware update is a part of it.
