Parallels 12 - Hypervisor: Parallels or Apple? The new version 12 of Parallels Desktop For Mac has a new configuration option. In the configuration panel > Hardware > CPU &amp; Memory > Advanced Settings > Hypervisor is a popup menu for:


Hypervisor


Parallels
Apple



Which one do I should I be using when running macOS Sierra as the guest OS?

What exactly is the difference, the pros-and-cons of each?

The Parallels app Help has no mention of this new setting.
This post in Parallels Forum clearly states to use Parallels Hypervisor:

Hi, Apple hypervisor comes short of the following matters comparing to the Parallels hypervisor:

Performance: slower on VM startup and shutdown

Stability: may crash more frequently

Functionality loss: no PMU, nested virtualization, thermal monitoring, energy profiling


Parallels Hypervisor is the best one.
