m1craft

Run Minecraft 1.17 and 1.18 without installing any profiles, json files, or jars.

This tool does not modify either the Minecraft JAR or LWJGL JARs. The Minecraft JAR is downloaded unmodified from Minecraft, and the LWJGL jars are pre-built 3.3.0 directly from lwjgl.org

Download: https://m1craft.ezekiel.dev

Warning: Do not use the Minecraft fullscreen option, instead use the system one (green button). If you've used the Minecraft one and it's crashing, follow the steps here

Tip: If you would like to run custom versions that do not appear selectable in the UI, you can set the version to play manually via terminal:

defaults write dev.ezekiel.m1craft selected-version "<version here>"

Note: 1.18 and later can be run directly from the official Minecraft launcher. Follow instructions here if you'd prefer to do this instead – including if you need to mod the game. However this launcher is still easier (no install steps needed).
