Installation on macOS Platforms

Installation on macOS Platforms #

GraalVM is available for macOS on x64 and AArch64 architectures.

Note that on macOS the JDK installation path is: _/Library/Java/JavaVirtualMachines//Contents/Home_.

Follow these steps to install GraalVM:

Navigate to the GraalVM Downloads page. Select 17 or 20 for the Java version, macOS for the operating system, x64 or aarch64 for the architecture, and download.
Unzip the archive.
```
 tar -xzf graalvm-jdk-<version>_macos-<architecture>.tar.gz
```
Alternatively, open the file in Finder.
Note: If you are using macOS Catalina and later you may need to remove the quarantine attribute:
```
 sudo xattr -r -d com.apple.quarantine /path/to/graalvm
```
Move the downloaded package to its proper location, the /Library/Java/JavaVirtualMachines directory. Since this is a system directory, sudo is required:
```
sudo mv graalvm-jdk-<version>_macos-<architecture> /Library/Java/JavaVirtualMachines
```
To verify if the move is successful and to get a list of all installed JDKs, run /usr/libexec/java_home -V.
There can be multiple JDKs installed on the machine. The next step is to configure the runtime environment:
- Set the value of the PATH environment variable to the GraalVM bin directory:
```
 export PATH=/Library/Java/JavaVirtualMachines/<graalvm>/Contents/Home/bin:$PATH
```
- Set the JAVA_HOME environment variable to resolve to the GraalVM installation directory:
```
 export JAVA_HOME=/Library/Java/JavaVirtualMachines/<graalvm>/Contents/Home
```
To check whether the installation was successful, run the java -version command.

Optionally, you can specify GraalVM as the default JRE or JDK installation in your Java IDE.

Installation Notes #

On JAVA_HOME Command #

The information property file, Info.plist, is located in the top-level Contents/ directory. This allows GraalVM to integrate with the macOS-specific /usr/libexec/java_home mechanism. Depending on other installed JDKs, running /usr/libexec/java_home -v<version> may return /Library/Java/JavaVirtualMachines/<graalvm>/Contents/Home. To view all JVMs recognized by java_home, run /usr/libexec/java_home -V. This command lists JVMs in descending version order.
