Differential Growth Pattern On Mac

Hey everyone, I am learning Grasshopper in my design class and I am tasked with creating a 2d pattern in a couple weeks. I really want to create unique organic differential growth patterns, however, most of these I have seen use plugins like anemone which I am not able to get on my MacBook. Does anyone know if it is possible to create someone like this without these plugins?

Also Anemone can be installed in Rhino for macOS and works flawlessly.
