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.
Disclaimer
- 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.
- Unless Noggisoggi is willing to help, then in which case, you may ask him for help on the discord.
- Some basic computing knowledge, such as extracting files, moving, copying, etc. are mandatory.
