Installing Java on macOS

This guide will walk you through installing Java 25 on macOS.

The Minecraft Launcher comes with its own Java installation, so this section is only relevant if you want to use the Fabric .jar based installer, or if you want to use the Minecraft Server .jar.

1. Check if Java Is Already Installed

In Terminal (located in /Applications/Utilities/Terminal.app) type the following, and press Enter:

$(/usr/libexec/java_home -v 25)/bin/java --version

You should see something like the following:

openjdk 25.0.2 2026-01-20 LTS
OpenJDK Runtime Environment Temurin-25.0.2+10 (build 25.0.2+10-LTS)
OpenJDK 64-Bit Server VM Temurin-25.0.2+10 (build 25.0.2+10-LTS, mixed mode, sharing)

Notice the version number: in the example above it is 25.0.9.

WARNING

To use Minecraft 26.1, you'll need at least Java 25 installed.

If this command displays any version lower than 25, you'll need to update your existing Java installation; keep reading this page.

2. Downloading and Installing Java 25

We recommend using Adoptium's build of OpenJDK 25:

Make sure to select version "25 - LTS", and choose the .PKG installer format. You should also choose the correct architecture depending on your system's chip:

• If you have an Apple M-series chip, choose aarch64 (the default)
• If you have an Intel chip, choose x64
• Follow these instructions to know which chip is in your Mac

After downloading the .pkg installer, open it and follow the prompts:

You will have to enter your administrator password to complete the installation:

Using Homebrew

If you already have Homebrew installed, you can install Java 25 using brew instead:

brew install --cask temurin@25

3. Verify That Java 25 Is Installed

Once the installation is complete, you can verify that Java 25 is active by opening Terminal again and typing $(/usr/libexec/java_home -v 25)/bin/java --version.

If the command succeeds, you should see something like this:

openjdk 25.0.2 2026-01-20 LTS
OpenJDK Runtime Environment Temurin-25.0.2+10 (build 25.0.2+10-LTS)
OpenJDK 64-Bit Server VM Temurin-25.0.2+10 (build 25.0.2+10-LTS, mixed mode, sharing)
