Sorry for taking so long to reply. Funnily enough I’ve been working on iOS apps lately — so haven’t been on the forum — and bought an M1 MacBook Pro on release day to use for these projects.
Having just picked up another Elixir project I decided to have a go with the M1 rather than my Ryzen-based desktop just to benefit from that mobility (and the insane battery life).
As I’m sure you’ll know by now from other threads/blog posts, Elixir runs brilliantly on Apple Silicon. With brew now supporting AS natively, install and setup is easy and I’ve yet to have any problems. I’m using PostgreSQL through Postgres.app which does use Rosetta, but as-per pretty much every other Rosetta app, it’s been problem-free.
Performance is really good. The Erlang VM sees (and appears to use) all 8 cores and compilation speed seems pretty comparable to my Ryzen 3600. No complaints from me!
