I just installed Julia 1.11 and when i try to open the app, it fails as follows.
I’m using MacOS Sequoia 15.5.
Is this known?

If you’re manually installing the DMG file, yes: [DMG install (may be) broken on newer versions of macOS · Issue #2291 · JuliaLang/www.julialang.org · GitHub](https://github.com/JuliaLang/www.julialang.org/issues/2291). It should be fixed in future versions of julia.
But also, consider using Juliaup instead: [Install Julia](https://julialang.org/install/).

i can call julia from the command line with: ‘julia’
but i do not have this juliaup installed, cuz i tried to look with ‘juliaup --version’ and the command is not known.
What would you recommend me to do?
Uninstall some how my current Julia 1.9 and then start from scract an install juliaup and Julia 1.11

`juliaup` is a separate program that takes care of installing and maintaining different Julia versions on a single machine. Installation instructions can be found here: [GitHub - JuliaLang/juliaup: Julia installer and version multiplexer](https://github.com/JuliaLang/juliaup?tab=readme-ov-file#mac-linux-and-freebsd)
Once `juliaup` is available on your system, you can easily install any Julia version (e.g., `juliaup add 1.10` to install Julia v1.10) a start it (e.g., `julia +1.10` to start the REPL of Julia v1.10). See more instructions at [GitHub - JuliaLang/juliaup: Julia installer and version multiplexer](https://github.com/JuliaLang/juliaup?tab=readme-ov-file#using-juliaup)

Thanx for the reply.
Yet, the question was if i should “ **Uninstall** some how my current Julia 1.9” first ?
before installing `juliaup`?

It doesn’t hurt. I would simply uninstall any previously installed version before installing the `juliaup` manager. The experience is much improved.

I think it’s better to ininstall the current Julia v1.9. If you have installed it through DMG, then trashing `Julia1.9.app` should do the job. I do not remember exactly how I proceeded when switched from DMG to `juliaup` – which is probably an indicator it was painless enough.
