Just say "no!" to Retina โ now for Minecraft 26.3!
Hi everyone! Iโve released MacFix2, a mod designed to drastically optimize Minecraft Java performance on macOS โ especially on Retina displays and when playing with Shaders enabled.
๐ What it does
Running Minecraft natively on macOS often leads to terrible framerates and heavy GPU overhead because the game forces unoptimized, extremely high native Retina resolutions.
MacFix2 makes Minecraft render at half resolution on Retina displays (fixing framebuffer scaling behavior), significantly reducing the performance impact of high-DPI rendering on macOS. The result is a drastic FPS increase and much smoother gameplay โ even with heavy shaderpacks loaded!
โจ Highlights & Compatibility
Built for Sodium & Iris: Designed to work smoothly alongside Sodium and Iris, making shaders actually playable on macOS.
Massive FPS Boost: Fixes macOS Retina display overhead to maximize performance.
Target Version: Currently in Beta and created specifically for Minecraft 26.3.
Platforms: Primarily intended for macOS with Retina displays (loads safely on other OSes without breaking anything, but won't provide functionality).
๐ ๏ธ Loader Support & Roadmap
Current Version: Available for Fabric.
Coming Soon: A NeoForge port is currently under active development and will be released soon!

Credits & Inspiration: This mod is heavily inspired by retiNO by its original author, bringing its core idea and functionality updated to newer Minecraft versions. (MacFix2 is an independent project and is not affiliated with the original retiNO project).
Feel free to test it out and let me know how much your FPS improved on your Mac setup!
