Try compiling it from the GitHub repo, in particular, the maint branch, as there have been some fixes related to BigSur recently: https://github.com/erlang/otp/pull/2865

it does on master and it is glorious.

Very smooth fully native M1 Arm installation now via latest Homebrew and asdf-vm; be sure to install the Erlang dependencies autoconf and wxmac before installing Erlang, as specified in the asdf-erlang instructions.

Of note: the scheduler sees all 8 cores, including the low-power ones:

Erlang/OTP 23 [erts-11.1.7] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1]

so it might be interesting to learn how that performs in practice.

After a chat with @dch on IRC we’re noticing that :erlang.system_info :cpu_topology returns :undefined which may be part of the issue. Will update with followup.

Thanks Jose!

I was able to get everything working by installing homebrew using rosetta 2. I followed this guide: https://soffes.blog/homebrew-on-apple-silicon

Still haven’t had much success installing older versions or using ASDF but 1.11 will work for what I need.
