 ### Warning for macOS
-There is currently [the following](https://github.com/JuliaPackaging/BinaryBuilder.jl/issues/700) issue between the artifacts used by `SpecialFunctions.jl` and `MKL_jll`. Unless `IntelVectorMath` is loaded first, there might be wrong results coming from a small number of function for particular input array lengths. 
+There is currently [the following](https://github.com/JuliaPackaging/BinaryBuilder.jl/issues/700) issue between the `CompilerSupportLibraries_jll` artifact, which is used for example by `SpecialFunctions.jl`, and `MKL_jll`. Unless `MKL_jll` is loaded first, there might be wrong results coming from a small number of function for particular input array lengths. If you are unsure which, if any, your used packages might load this artifact, loading `IntelVectorMath` as the very first package should be fine.
