The conda-forge osx-64 Julia builds stopped working around the beginning of 2026 with the last build being Julia 1.12.2 on December 12th, 2025. The conda-forge builds are (mostly) built from source.
I was able to resolve the build issues with the help of Claude via PR 309. Julia 1.12.7 osx-64 builds as well as Julia 1.12.7 linux-64 builds are now available from conda-forge.
This complements the repackaged official binaries from the julia-forge channel which are available for linux-64, linux-aarch64, osx-arm64, and win-64 platforms, using the conda architecture names.
The main utility of these packages are for projects using multiple programming languages.
These packages can be installed via pixi, mamba, or conda.
