BetaEvolutions

BetaEvolutions (BetaEvo or BetaEVO, https://evolutions.johnymuffin.com) is a Minecraft Beta 1.7.3 mod to fix sounds, skins and authentication; created by JohnyMuffin (GitHub, J-Stats).

Features

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

This guide is written with MultiMC & its forks in mind; it also assumes you created a Beta 1.7.3 instance.
Your mileage may vary; please do not bug the volunteer staff regarding this.
- Unless Noggisoggi is willing to help, then in which case, you may ask him for help on the discord.
Some advanced computing knowledge, such as extracting files, moving, copying, etc. are mandatory.

Get an x86 build of the JRE for macOS
- Head to: https://www.azul.com/downloads/?version=java-8-lts&os=macos&architecture=x86-64-bit&package=jre#zulu & download the zip/tar archive.
Open your downloads folder & extract the archive.
Open your launcher; PrismLauncher or MultiMC in this case.
Select your instance of Beta 1.7.3, select Folder
- Your b1.7.3 instance folder should open.
- If not: open the Finder, select Go to Folder... & input this path:
- PrismLauncher: ~/Library/Application Support/PrismLauncher/instances/
- MultiMC: ~/Library/Application Support/MultiMC/instances/
- Press [Return] or [Enter] & go to your b1.7.3 instance.
Copy that JRE you extracted directly into the instance folder.
Back in MultiMC/PrismLauncher, select your b1.7.3 once more & select Edit Instance
- Select: Settings->Java installation->Browse
- A file picker should pop-up; head to instances-> your b1.7.3 instance -> the JRE you extracted->bin->java
Launch the game and pray it works.
