Is it possible to use Parallels instead of Virtualbox to make a functioning lab?
I’ve found that my mac works much faster with parallels than with Virtual Box, which is consuming more resources of my mac.
Actually I don’t know if parallels has the capability to creat a NAT Netwrok, cause this is necessary for the machine to communicate each other.
If Using VBox you are getting laggy machines, you can try this:
The only solution to this is to reduce the resolution before starting Kali, you can do that using an app called “resolution changer”, download it from the app store, set the resolution to 1080p and it should work.
