How to enable support of CPU virtualization on Macbook Pro

Question

I have the VirtualBox installed on my Macbook Pro  and I want to install a linux VM on VirtualBox  When I launched the new VM  it prompts that  Your CPU does not support long mode   Use a 32bit distribution    After searching for this problem  I found that support of CPU virtualization is required for this VM  Then I checked on my Macbook and its CPU is i7 which supports virtualization  So I guess the problem is related to the OS or EFI version   OS version  10 6 8   EFI version  latest  check on apple com   Does anyone know what s the problem of my Macbook   How can I enable the support of CPU virtualization

CPU Virtualization is enabled by default on all MacBooks with compatible CPUs (i7 is compatible). You can try to reset PRAM if you think it was disabled somehow, but I doubt it.

I think the issue might be in the old version of OS. If your MacBook is i7, then you better upgrade OS to something newer.
