ManyMC

A familiar Minecraft Launcher with native support for macOS arm64 (M1)


⚠️ The ManyMC launcher is no longer being updated.

Prism Launcher is the official continuation of ManyMC. It is actively developed by numerous maintainers, and directly inherits all of ManyMC's ARM patches. Migrating is super easy:

  1. Close all launchers
  2. Run the following commands from a Terminal:

    cd ~/Library/Application\ Support
    mv ManyMC PrismLauncher
    cd PrismLauncher
    mv manymc.cfg prismlauncher.cfg
    rm -r meta metacache cache libraries

Find Prism here: \ https://github.com/PrismLauncher/PrismLauncher \ https://discord.gg/prismlauncher

The ManyMC Discord guild is not going away, and it continues to be a place to reach me. Feel free to join: \ https://discord.gg/CcFxPaDnjv


Supported versions

All stable versions of Minecraft from 1.6.4 to the latest have been tested and work great. Fabric, Forge, and OptiFine also work across all versions. Even huge modpacks like All the Mods 6 run perfectly!

Can't sprint and attack at the same time? Or sneak and scroll? These are all old and unfixed Minecraft bugs on macOS. Get rid of them now using our mod McMouser (CurseForge).

Install

There are two ways to install ManyMC, please choose one:

Homebrew (recommended)

  1. Install brew if you haven't already

  2. In a Terminal, run the following commands one by one. This will install the correct versions of Java 8, Java 17, and ManyMC:

    brew tap homebrew/cask-versions
    brew install zulu8 zulu17
    brew install --no-quarantine ManyMC
  3. Run ManyMC as normal (it's in /Applications/ManyMC)

  4. Depending on which version of Minecraft you want to play, you will need to use a different version of Java. Use the table below to find the correct Java path for your Minecraft version, and select it when ManyMC prompts you:

    Minecraft Version Java Version Architecture Path
    1.16 and below 1.8.0_X aarch64 /Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home/bin/java
    1.17 and above 17.X.X aarch64 /Library/Java/JavaVirtualMachines/zulu-17.jdk/Contents/Home/bin/java

    :information_source: NOTE: You can always change the Java version individually by selecting a Minecraft instance and clicking on Edit instance > Settings > Java installation.

  5. To update ManyMC in the future, simply run the following command in a Terminal, your data will not be affected:

    brew upgrade --no-quarantine ManyMC

Manual

  1. Make sure you have the correct arm64 native Java installed for the version of Minecraft you want to play. Check step 4 in the section above if you don't know. For example, you can use Azul OpenJDK 17 arm64 or Azul OpenJDK 8 arm64.

  2. Download the latest release of ManyMC and extract it. You can move the app to your "Applications" folder if you like.

  3. Start ManyMC. If it gives an error about "developer cannot be verified", one time only, do not double-click on the app, but instead right-click on it and press Open, then Open again.

  4. As you go through the initial setup, make sure to select the correct arm64 native Java for the version of Minecraft you want to play. For example, for Minecraft 1.17, you will need Java 17, like so:

    :information_source: NOTE: You can always change the Java version individually by selecting a Minecraft instance and clicking on Edit instance > Settings > Java installation.

  5. To update ManyMC in the future, simply delete the app and replace it with the new version from this GitHub page. Your data will not be affected.

Troubleshooting

How does it work

Minecraft is mostly written in Java, which means that as long as you have a native arm64 Java installed, you can almost run the game natively. The only exception are some libraries like LWJGL, which have platform-specific binaries. Fortunately, all of them are open-source, so they can be re-built to work.

This launcher is a fork of PolyMC, since the latter does not yet natively support arm64. To comply with PolyMC's licensing, this launcher was rebranded to ManyMC. To use the custom native libraries, a dedicated meta package has been created.

Building

⚠️ This will only work on macOS. Tested on macOS 12.1 arm64.

  1. Install dependencies:

    brew tap homebrew/cask-versions
    brew install zulu8 qt@5 cmake
  2. Install XCode and make sure the command line tools are set up:

    xcode-select -p
  3. Run a build:

    ./build.sh
    • You will need your own secrets if you want login with Microsoft account to work. Copy notsecrets to a new directory called secrets and follow the README inside.
    • If you get weird Java errors, you may have to manually set your JAVA_HOME to the zulu8 you just installed.
