How to check VT-x status on MacBook Pro I need to enable VT-x on my MacBook Pro, but I don't know whether it's enabled or not. Are there commands for checking the status of, enabling, or disabling VT-x?

Those are my device specifications:

MacBook Pro (Retina, 13-inch, Early 2015)

OS: OS X El Capitan 10.11.2
CPU: 2.7 GHz Intel Core i5 
RAM: 8 GB 1867 MHz DDR3
According to Intel® Core™ i5-5257U Processor, it supports Intel Virtualization Technology (VT-x).

You can also from Terminal use the following command:

sysctl -a | grep machdep.cpu.features


If you see VMX in the output, then the CPU supports the Intel VT-x feature.

If you don't want to have to read through the output of CPU features and just see if VMX is there, then use: sysctl -a | grep -o VMX

From Intel-based Macs: Using VT-x virtualization technology:


  Intel VT-x technology is enabled on Intel-based Macs. Make sure your Intel-based Mac has all available EFI updates installed; also update any third-party virtualization software.


Therefore there is no reason to check the status.

As to enabling/disabling, there is no direct user interface for that.  Since it is enabled by default, the only way I can think of to disable it would be to hack the EFI Firmware. Which is not something I'd recommend doing!
