How can I find out if a CPU supports unrestricted mode / unrestricted guest mode? For example, this link mentions it https://software.intel.com/en-us/forums/virtualization-software-development/topic/277958 But is there any software that displays it? I didn't notice it mentioned in CPU-Z

 https://developer.apple.com/documentation/hypervisor "Generally, machines with an Intel VT-x feature set that includes Extended Page Tables (EPT)and Unrestricted Mode are supported"

See Section 31.5.1, Algorithms for Determining VMX Capabilities, in Volume 3C of the Intel® 64 and IA-32 Architectures Software Developer’s Manual.

 

Hope this helps,
