I need to enable hardware virtualization on my MacBook Air 2013. I want to run the Windows Phone 8 emulator, which requires hardware virtualization. I am running Windows 8 in boot camp. On my old PC, I enabled it through the BIOS, but this option won't work for a MacBook.

The MacBook Air 2013 has a i5-4250U processor, which is on Intel's list of Virtualization Technology supported processors.

How would this be done?

In the performance tab of Task Manager, Virtualization appears to be disabled.enter image description here

After hours of searching the internet, I discovered how to enable virtualization in Boot Camp. Instead of booting into Windows by holding the option key on startup, boot in to OS X. Then go to System Preferences -> Startup Disk and choose your Boot Camp partition. The computer will restart and boot into Windows, with virtualization enabled.

    It works because OSX enables Virtulisation by default. The Bootcamp Drivers do not. Hence, by going into OSX first then rebooting into Windows it works. When rebooting into Windows from OSX it's not a cold boot, therefore the virtualisation settings are still enabled from booting into OSX. – dotnethaggis Apr 27 '15 at 7:31
  • Looks like the latest update to OSX has resolved it. I finally can install Windows10. For the record, I'm running Win10 Anniversary edition. – Sean Feldman Aug 17 '16 at 16:14

Just open Powershell (Admin) and type install/enable it from command.

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All

Restart the computer when prompt, and there you have Virtualization enabled. Same if you want to install Hyper-v in Virtual machines.

To get GUI Hyper-V manager under Server tools, click on Add roles and features > Features > Remote server administration tools > Role administration tools > Hyper-V management tools

I hope this helps.

    This is not about installing the Hyper-V components, it's about enabling virtualization CPU in the processor at boot – John Leidegren Nov 15 '18 at 7:44
