How to Set JAVA_HOME on Mac | Setting Up JAVA_HOME on macOS (2026)

Setting the JAVA_HOME environment variable on macOS is an essential step for Java developers and anyone working with Java-based tools. In this tutorial, you will learn how to set JAVA_HOME on Mac step by step. This guide works on macOS running on Apple Silicon (M1, M2, M3, M4, M5) as well as Intel-based Macs, including MacBook Pro, MacBook Air, and iMac. We start by explaining what JAVA_HOME is and why it is important. JAVA_HOME is an environment variable that points to the location of the Java Development Kit (JDK) installed on your system. Many tools and frameworks such as Maven, Gradle, Tomcat, Spring Boot, Hadoop, and IDEs like IntelliJ IDEA, Eclipse, and VS Code rely on JAVA_HOME to function correctly. If JAVA_HOME is not set properly, Java commands and applications may fail to run. In this video, you will first learn how to check whether Java is already installed on your Mac and how to identify the installed JDK version. We explain how macOS manages Java installations and how to locate the correct JDK path using terminal commands. This step is important, especially when multiple Java versions are installed on the same system. Next, we walk through the complete process of setting JAVA_HOME on macOS using the terminal. You will learn how to configure JAVA_HOME for popular shells like zsh and bash by editing the appropriate configuration files such as `.zshrc` or `.bash_profile`. Each command is explained clearly so beginners can follow along without confusion. We also demonstrate how to export JAVA_HOME correctly and update the PATH variable so that Java commands like `java` and `javac` work seamlessly from the terminal. You will learn how to make these changes permanent so JAVA_HOME is available every time you open a new terminal session. After setup, we show how to verify that JAVA_HOME is set correctly on macOS. You will learn how to print the JAVA_HOME value in the terminal and confirm that your system is using the correct Java version. Common issues faced by Mac users are also covered, such as JAVA_HOME not being recognized, incorrect JDK paths, conflicts between multiple Java versions, and Apple Silicon–specific concerns. Practical troubleshooting tips are provided to help you resolve these problems quickly. By the end of this tutorial, you will have JAVA_HOME properly configured on your Mac and be ready to work with Java applications and tools without any issues. This video is ideal for Java beginners, students, and developers working on macOS.
