Stencil Fix is a CoreMod that fixes the Blackscreen with macOS on Minecraft 1.5.2 + Forge. This is caused by a java update 8u252+ which broke LWJGL 2.9's stencil buffer. The mod works by making forge not use the stencil buffer if and only if your running macOS with java 8u252 or higher. This is a small mod please enjoy.
Installation:
- Drop into .minecraft/coremods (It doesn't work in the mods folder as 1.5.2 coremods only loaded in the coremods folder)
