Install and run Kafka in KRaft mode on macOS in 10 minutes KRaft mode runs Kafka without ZooKeeper, simplifying deployment and reducing resource requirements. This guide walks you through setting up a single-node KRaft cluster. What you’ll learn:
  • How to install Java 11 (required dependency)
  • How to generate a cluster ID and format storage
  • How to start Kafka in KRaft mode
  • How to configure your PATH for CLI access
KRaft vs ZooKeeperKRaft mode became production-ready in Kafka 3.3. For maximum compatibility with older tutorials and tools, see the Mac ZooKeeper installation guide.

​
Installation overview

​
Step 1: Install Java JDK 11

Kafka requires Java 11 or later.
  1. Download Amazon Corretto 11 (free OpenJDK distribution)
  2. Double-click the downloaded .pkg file
  3. Follow the installation wizard
Verify the installation: 
java -version
Expected output: 
openjdk version "11.0.10" 2021-01-19 LTS
OpenJDK Runtime Environment Corretto-11.0.10.9.1 (build 11.0.10+9-LTS)
OpenJDK 64-Bit Server VM Corretto-11.0.10.9.1 (build 11.0.10+9-LTS, mixed mode)

​
Step 2: Download and extract Kafka

Download from kafka.apache.org/downloads (choose the latest binary with Scala 2.13) and extract: 
cd ~/Downloads
tar -xzf kafka_2.13-3.0.0.tgz
mv kafka_2.13-3.0.0 ~/

​
Step 3: Generate cluster ID

KRaft clusters require a unique identifier: 
~/kafka_2.13-3.0.0/bin/kafka-storage.sh random-uuid
This returns a UUID like 76BLQI7sT_ql1mBfKsOk9Q. Save this value.

​
Step 4: Format storage

Format the log directory using your cluster ID (replace <uuid> with your generated UUID): 
~/kafka_2.13-3.0.0/bin/kafka-storage.sh format \
  -t <uuid> \
  -c ~/kafka_2.13-3.0.0/config/kraft/server.properties
This formats the directory specified in log.dirs (default: /tmp/kraft-combined-logs).

​
Step 5: Start Kafka

~/kafka_2.13-3.0.0/bin/kafka-server-start.sh ~/kafka_2.13-3.0.0/config/kraft/server.properties
Keep this terminal window open. Kafka is now running at localhost:9092 in KRaft mode.

​
Step 6: Configure PATH

Add Kafka binaries to your PATH for convenient access. Edit your shell configuration file (~/.zshrc for zsh or ~/.bashrc for bash): 
export PATH="$PATH:$HOME/kafka_2.13-3.0.0/bin"
Reload your shell: 
source ~/.zshrc
Verify the setup: 
kafka-topics.sh --version
See it in practice with ConduktorConduktor Console can connect to your KRaft cluster at localhost:9092 for visual topic management.
