Hi everyone,

I’m currently setting up `RigidBodySim.jl` and `RigidBodyDynamics.jl` on a modern macOS system (MacBook Air M2, macOS Sonoma) using Julia 1.9.4 and 1.10.2.

My goal is to get a complete and stable simulation setup \*including browser-based visualization\* via `MeshCatMechanisms.jl`.

So far, I ran into a few problems related to package compatibility (e.g. `AdaptStaticArraysExt` errors, version mismatches) and would love to hear from anyone who has a working setup.

### ❓ Specific questions:

- What’s the latest Julia version that works reliably with:

- `RigidBodySim.jl`

- `RigidBodyDynamics.jl`

- `MeshCat.jl`, `MeshCatMechanisms.jl`

- `StaticArrays.jl`, `Colors.jl`

- Is there a known-good combination of `Project.toml` and `Manifest.toml` for these packages?

- Is the MeshCat-based browser visualization workflow still supported in the current ecosystem?

- Any tips from people using this in teaching or research?

### 💻 My setup:

- macOS Sonoma

- Julia 1.9.4 (and 1.10.2 tested)

- Apple Silicon (M2)

- Installed via GitHub master branches (RigidBodySim, MeshCat, etc.)

I already posted an [issue here on GitHub]( [Recommended setup for RigidBodySim.jl with browser-based visualization (Julia 1.9+ on macOS) · Issue #131 · JuliaRobotics/RigidBodySim.jl · GitHub](https://github.com/JuliaRobotics/RigidBodySim.jl/issues/131) ), but the project hasn’t been active lately. Any help or updated guidance would be much appreciated!

Thanks a lot in advance 🙏

The latest version of MeshCat.jl works well for me on Julia 1.11. The issue seems to be with RigidBodySim.jl’s [compat requirements](https://github.com/JuliaRobotics/RigidBodySim.jl/blob/master/Project.toml). As it looks like the package is unmaintained, you may want to fork and `dev` that package to fix its compat requirements. See: [6. Compatibility · Pkg.jl](https://pkgdocs.julialang.org/v1/compatibility/#Fixing-conflicts)

Thank you for your reply. It helped me a lot to understand the issue which I had with RigidBodySim.jl.

I will now learn more about RigidBodyDynamics.jl and see if I can easily avoid using RigidBodySim.jl.
