Hi all! I found an optimized version of Java for Apple's new M1 chip. I'd like to see what Minecraft (java edition) is like with an optimized runtime for the new hardware.

Azul has an optimized build for AArm64 (Apple Silicon) but I'm having trouble getting Minecraft to launch with it.

Here's the link to the JDK - https://www.azul.com/downloads/zulu-community/?os=macos&architecture=arm-64-bit&package=jdk

And the error I'm getting is that it can't find the lwjgl.dylib (light weight java game library). I've copied it from the Minecraft folder into the new JDK folder as well as added a library path flag on the JVM command.

Can't wait to see the FPS!

Thanks!

I was able to play Minecraft using the Azul Zulu 11 JDK built for arm64.

Today i upgraded Minecraft to version 1.17 which was released recently and has great new features. It now requires Java 16 and comes bundled with a x86_64 java binary on MacOS which works on M1 Macs but offers less than stellar performance.

I installed Azul Zulu 16 for arm64 and configured my Minecraft launcher profile to use it (path: /Library/Java/JavaVirtualMachines/zulu-16.jdk/Contents/Home/bin/java ).

Unfortunately the game crashes on launch. Has anyone gotten it to work with the arm64 java binary?
