when plist will get added to the registry?

Hi


I am trying to Write a Serial/ACM driver for mac os Catalina Since all these kind of drivers has to be moved to User Space (as per wwdc 2019). So I am Planning to use driver kit, usb serial driver Kit and Serial driver kit.

I am new to KEXT and DEXT.

I have a doubt regarding plist.

In our kext driver during driver initialization, getProperty reads from registry. So when plist items gets added to the registry?
