macos - 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?

Answer 1

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.
