 ## Minikube on Mac
 
 This tutorial is heavily inspired by the article [How to implement Hyperledger Fabric External Chaincodes within a Kubernetes cluster](https://medium.com/swlh/how-to-implement-hyperledger-fabric-external-chaincodes-within-a-kubernetes-cluster-fd01d7544523) by Pau Aragonès Sabaté. Thank you!
+Note:
+You might run into issues if your Mac has an M1 processor or above. If you install minikube using brew it might detect your environment as amd64 and not arm64, install the arm64 binaries. Another point is that if you have set DOCKER_DEFAULT_PLATFORM=linux/amd64 that will also generate errors. Set it in the terminal to Linux/arm64 and your minikube/docker environment should start.
