 # Requirements
 
-Kafka will be exposed on `127.0.0.1` or `DOCKER_HOST_IP` if set in the environment.
-(You probably don't need to set it if you're not using Docker-Toolbox)
-
-## Docker-Toolbox
-Docker toolbox is [deprecated](https://github.com/docker-archive/toolbox) and not maintained anymore for several years.
-We can't guarantee this stack will work with Docker Toolbox, but if you want to try anyway, please export your environment before starting the stack:
-```
-export DOCKER_HOST_IP=192.168.99.100
-```
-(your docker machine IP is usually `192.168.99.100`)
+Kafka will be exposed on `127.0.0.1`.
 
-## Apple M1 support
-Confluent platform supports Apple M1 (ARM64) since version `7.2.0`! Basically, this stack will work out of the box. 
+## Apple M4 Support
 
-If you want to downgrade confluent platform version, there are two ways:
+At the time of writing there is an issue with Apple M4 chip machines and running certain Java based Docker images.
 
-1. Add `platform: linux/amd64`. It will work as docker is able to emulate AMD64 instructions.
-2. Previous versions have been [built](https://github.com/arm64-compat/confluent-platform) for ARM64 by the community. If you want to use it, just change the image in the corresponding yml. Since it is a not an official image, use it at your own risks.  
+Modify the `conduktor.yml` file, uncomment the environment variable `CONSOLE_JAVA_OPTS: "-XX:UseSVE=0"`.
