According to [https://github.com/JuliaLang/julia/issues/31465](https://github.com/JuliaLang/julia/issues/31465) I should report such issues on discourse, so here we are…

I am not able to install Julia 1.2.0 on a freshly installed latest macOS Mojave (10.14.6) with a shiny new homebrew installation due to a checksum error:

```julia

```

I downloaded the image multiple times but it has the same checksum, so I assume the recipe has to be updated.

You should probably report this to the homebrew maintainers then (at the url printed above)

Hm it’s not an issue with homebrew, it’s an issue with the recipe. I don’t know who is the maintainer of the Julia recipe but @mb1248 (on GitHub) pushed the last commit to the repository: [https://github.com/Homebrew/homebrew-cask/blob/master/Casks/julia.rb](https://github.com/Homebrew/homebrew-cask/blob/master/Casks/julia.rb)

Anyways, I’ll report there…

It seems that the recipe was fixed. It works now 😉
