Installation on macOS Platforms

Oracle GraalVM is available for macOS on x64 and AArch64 architectures.

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

Follow these steps to install Oracle GraalVM:

Navigate to Oracle Java Downloads. Select the preferred Oracle GraalVM version, 21 for the Java version, macOS for the operating system, and the architecture. Start downloading.
Unzip the archive:
```
tar -xzf graalvm-jdk-<version>_macos-<architecture>.tar.gz
```
Alternatively, open the file in the 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 JAVA_HOME environment variable to resolve to the 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 Oracle 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 folder. This means that Oracle GraalVM participates in the macOS-specific /usr/libexec/java_home mechanism. Depending on other JDK 17 installation(s) available, it is now possible that /usr/libexec/java_home -v21 returns /Library/Java/JavaVirtualMachines/<graalvm>/Contents/Home. You can run /usr/libexec/java_home -v21 -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.
