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?
