ℹ️ Notice: A development version of BetaEvolutions no longer needs this method - see BetaEvolutions for more info. This page is kept for the release version.


Due to BetaEvolutions' Discord RPC library not having a macOS arm64 version, a workaround via an x86-64 Java runtime environment has to be used.

⚠️ Disclaimers:

  • This guide is written with MultiMC & its forks in mind; it also assumes you have already created a Beta 1.7.3 instance.
  • Your mileage may vary; please do not bug the volunteer staff regarding this.
    • Exception: You may contact Noggisoggi for help regarding this on the Discord server as he's the only one on the staff list with an Apple Silicon Mac.
  • Some basic computing knowledge, such as extracting files, moving, copying, etc. are mandatory.
  • This tutorial relies on the Rosetta 2 translation layer; should Apple remove this in a future macOS update, this tutorial will not work.

  1. Get an x86-64 build of the JRE for macOS
  2. This step will vary depending on what variant you downloaded:
    • Open your downloads folder and:
      • Extract the .tar.gz/.zip archive if you downloaded it.
      • Install the x86-64 JRE from the .pkg file.
  3. Open your launcher; PrismLauncher or MultiMC in this case.
    • Only for portable Java installs; skip to step 4 if you're using a system-wide install:
      • Select your instance of Beta 1.7.3, select Instance Folder or similar.
      • Your b1.7.3 instance folder should open.
        • If not: open the Finder, select View on the menu bar, then select: Go to Folder... & input one of these paths depending on your launcher:
          • PrismLauncher: ~/Library/Application Support/PrismLauncher/instances
          • MultiMC: /Applications/MultiMC.app/Data/instances
            • You need to open the context menu ([Right Click], [Ctrl]+[Left Click]) on MultiMC.app & select Show Contents.
        • Press [Return] or [Enter] & go to your b1.7.3 instance.
      • Copy that JRE you extracted directly into the instance folder.
  4. In MultiMC/PrismLauncher, select your b1.7.3 once more & select Edit Instance
    • Select: Settings -> Java installation -> Enable (tick) Java installation
      • System-wide installs:
        • Select Auto-detect & select the one with:
          • Version: 1.8.0_372
          • Architecture: x86_64
          • Path: /Library/Java/JavaVirtualMachines/temurin-8.jre/Contents/Home/bin/java
        • If the auto-detect method doesn't work for some reason, you can use the aforementioned path as the Java path.
      • Portable installs:
        • Method 1:
          • Select Browse.
          • A file picker should pop-up; head to instances -> your b1.7.3 instance -> the JRE you extracted -> bin/java.
      • Method 2:
        • Open your instance folder
        • Head to instances -> your b1.7.3 instance -> the JRE you extracted -> Contents/Home/bin/java.
        • Select the java binary.
          • Press Command+Option+C or open the context menu, hold Option & select Copy path.
        • Go back to the instance editor, select the entire Java binary path & replace it with what you have copied.
  5. Launch the game and pray it works.
