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/<graalvm>/Contents/Home.

Follow these steps to install GraalVM:

Navigate to the GraalVM Downloads page. Select 22 for the Java version, macOS for the operating system, x64 or aarch64 for the architecture, and download.

Remove the quarantine attribute (required for macOS Catalina and later):

 sudo xattr -r -d com.apple.quarantine graalvm-jdk-<version>_macos-<architecture>.tar.gz

Unzip the archive.

 tar -xzf graalvm-jdk-<version>_macos-<architecture>.tar.gz

Alternatively, open the file in Finder.

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 JAVA_HOME environment variable to resolve to the GraalVM installation directory:
```
 export JAVA_HOME=/Library/Java/JavaVirtualMachines/<graalvm>/Contents/Home
```
- Set the value of the PATH environment variable to the GraalVM bin directory:
```
 export PATH=/Library/Java/JavaVirtualMachines/<graalvm>/Contents/Home/bin:$PATH
```
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 in the top level Contents directory. This means that GraalVM participates in the macOS-specific /usr/libexec/java_home mechanism. Depending on other JDK installation(s) available, it is now possible that /usr/libexec/java_home -v22 returns /Library/Java/JavaVirtualMachines/<graalvm>/Contents/Home. You can run /usr/libexec/java_home -v22 -V to see the complete list of JVMs available to the java_home command. This command sorts the JVMs in decreasing version order and chooses the top one as the default for the specified version. Within a specific version, the sort order appears to be stable but is unspecified.
