I upgraded MacOS from Sequoia 15.3 to 15.4 this week. I also updated homebrew at the same time. Julia is installed via `juliaup` and is at 1.11.4.

Since the upgrade, julia fails to load `Arb_jll` needed by [`ArbNumerics.jl`](https://github.com/JeffreySarnoff/ArbNumerics.jl), with the error

```julia

The file `/Users/henry/.julia/artifacts/0aee3fc14042059a9f00ba046404366d5bdd7607/lib/libarb.dylib` exists and points to another existing file:

```julia
% file /Users/henry/.julia/artifacts/0aee3fc14042059a9f00ba046404366d5bdd7607/lib/libarb-2.14.0.dylib

```

Any help deciphering the error message is much appreciated!

I also nuked by `~/.julia` to verify there is no problem in there.

Works for me on macOS 14.4.1, I guess Apple broke something once again.

As a temporary workaround, someone suggested you may have some luck with

```julia
install_name_tool -delete_rpath /workspace/destdir/lib /Users/henry/.julia/artifacts/0aee3fc14042059a9f00ba046404366d5bdd7607/lib/libarb.dylib
install_name_tool -delete_rpath /workspace/destdir/lib /Users/henry/.julia/artifacts/0aee3fc14042059a9f00ba046404366d5bdd7607/lib/libarb.dylib

```

(yes, repeat the same command twice). And thank Apple for breaking loading of libraries in every other release.

Thanks, I did the above, and now I get

```julia
julia> using Arb_jll
zsh: killed julia

```

That’s it.

macOS is amazing, isn’t it? Every day making life harder for users.

Solution _might_ be simple. I made a PR: [libarb is merged into FLINT by hsgg · Pull Request #80 · JeffreySarnoff/ArbNumerics.jl · GitHub](https://github.com/JeffreySarnoff/ArbNumerics.jl/pull/80)
