brew install cmake wget ldid dpkg fakeroot gradle

# Give exec perm
chmod 755 *.sh

How can it work?

  • Use OpenJDK 16 from Procursus to get real Java environment.
  • Use MetalANGLE for OpenGL ES -> Metal translator.
  • Use GL4ES for OpenGL -> OpenGL ES translator.
  • Use our LWJGL3 iOS port.
  • Use same launch method as PojavLauncher Android.

Current status

  • Java Runtime Environment: OpenJDK 16.
  • LWJGL3 iOS port: works
  • OpenGL: GL4ES
  • Did Minecraft recognize OpenGL?
  • OpenAL: use @kcat's openal-soft
  • Input pipe implementation
  • Account authentication (partial).
  • Does it work? Partial.
  • Currently, only Minecraft 1.14+ fully works.
  • Forge won't work, but Fabric and OptiFine will.

Known issues

  • Mojang authentication might not work, but copying logged in account json from Android will work.
  • Camera position will be jumped to random location on first time touch.
  • 1.12.2 and below only render a tiny panorama at bottom left corner.
  • Other versions will crash for various reasons: Narrator crash, etc...
  • It may crash sometimes, but try launch again until you get it works.

Installing OpenJDK 16

For other jailbreak bootstrap

  • Download openjdk-16-jre.deb.
  • Install and open Filza File manager.
  • Go to where the .deb file downloaded.
  • Open it and press Install.
  • If everything fine, it will ends up with Setting up ....

  • Select a version: edit /var/mobile/Documents/minecraft/config_ver.txt, put to Minecraft version want to start.
