MacOS LWJGL Fix

by foxirl

MacOS LWJGL Fix is a Fabric client-side utility that addresses a crash seen on macOS with newer LWJGL builds.

FabricClient-side onlyMIT LicenseOpen source1.14 – 1.17.1

What it does

Players running the game on macOS can hit a crash when the LWJGL 3.3.0 library, or a later release, is in use. This mod targets that crash on the client, so only the player's installation needs it and servers run without it. Its single released file, 1.0.0, is built for 1.17.1, and the code is open source under the MIT License.

Key features

  1. Crash prevention on macOS

    Stops a crash that appears on macOS when the game runs LWJGL 3.3.0 or a later release.

  2. Targets the LWJGL library

    Works around the library's behavior on Apple systems rather than changing gameplay.

  3. Single-purpose fix

    Limits its scope to the one crash, so it adds no new blocks, items or commands.

What the author says

Fixes a crash when using LWJGL 3.3.0+ on older versions on MacOS. The crash happens because Minecraft tries to set an app icon for Minecraft, which is unsupported on MacOS. Previously, this did nothing, but in LWJGL 3.3.0+, it causes a crash.
