About this Mod

Apple Jam

This is a very simple mod designed to do one thing: add inventory jam support to macOS.

What is "Inventory Jam"?

According to the Minecraft Parkour Wiki, inventory jamming is opening the inventory, holding Forward + Jump, then closing the inventory to consistently perform a 0-tick timing (jam).

This is vanilla game behavior on Windows and Linux (in most cases). Unfortunately, it does not work on macOS, which can make things more difficult for parkour enthusiasts on a Mac. This mod fixes that, allowing you to enjoy it too :3

Frequently Asked Questions

Apple Jam server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.

Is Apple Jam compatible with fabric?

Apple Jam officially supports fabric for Minecraft 26.1.2, 26.1.1, 26.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Apple Jam – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Apple Jam consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
