How to Fix 'Red Screen' in Minecraft on OCLP Mac Pro

Resolving Minecraft Graphics Glitches in Sequoia

If Minecraft is stuck on a red screen on your 'Trashcan' Mac Pro, it's a conflict between the Java-based rendering and the legacy AMD FirePro patches.

The Fix:

  1. Java Version: Ensure you are using the latest OpenJDK 17 or 21. Older versions of Java have known issues with Sequoia's graphics stack.
  2. Disable Fullscreen: Launch Minecraft in windowed mode. You can do this by editing the options.txt file in your .minecraft folder and setting fullscreen:false.
  3. Metal Angle: If using the Prism Launcher, try changing the 'Graphics API' to Metal if available, or force OpenGL 3.3.
  4. Root Patches: Ensure both your Mac Pros are running the exact same OCLP version and root patches.
