### What is HyperKit?

HyperKit is a hypervisor built on top of the Hypervisor.framework in macOS. It runs entirely in userspace and has no other dependencies.
HyperKit is a legacy hypervisor built on top of Hypervisor.framework in macOS.
Previous versions of Docker Desktop for Mac used HyperKit to run the Linux VM.

configurations.
