Lichess Development Onboarding (macOS)

Note that development on macOS is not officially supported by the core team, but several community members have done it successfully.

Follow the Linux setup guide. Please note the following differences:

It is recommended to use the homebrew package manager. Most dependencies can be installed from there.

Lila

set play.server.netty.transport = "jdk" in conf/application.conf

lila-ws

Apple M1

Remove this line from build.sbt:

-libraryDependencies += "org.reactivemongo"           % "reactivemongo-shaded-native"  % s"$reactivemongoVersion-$os-x86-64"

Note that not all features of lila-ws have been thoroughly tested on mac, but it seems to work well enough for testing basic pvp gameplay.
