Hello everyone,
somehow I managed to render Julia completely useless on My Mac (it happened when I tried to update Julia to a newer version via this [thread](https://stackoverflow.com/questions/30555225/how-to-upgrade-julia-to-a-new-release))
Now every time I try to work with Julia I get the error message
```julia
ERROR: expected package `...` to be registered
```
It’s a package that I installed with git and that is not official and that I urgently need for my work.
Hence I want to completely reinstall Julia. But just by uninstalling the app in my applications there is some part of Julia left.
This is noticeable in the fact, that when I download and open the newer Julia version, I still find the same REPL history and of course I get the the same ERROR message.
**That’s why I ask you:** how to completely get rid of Julia (all startup and history files, that I didn’t seem to find) ?

Alright, as it is so often I probably found the solution directly after posting the question even if I spend hours before trying to find a solution.
I just clicked on the menu bar - go to folder - and typed - /Users/…/.julia
by removing all the content **in this folder** (that I can’t find with finder) Julia
seems to be completely blank.

If you download the .tar.gz archive ( [julia-1.9.4-macaarch64.tar.gz](https://julialang-s3.julialang.org/bin/mac/aarch64/1.9/julia-1.9.4-macaarch64.tar.gz)), you can expand it anywhere. Then create a script that will set the PATH and export the DEPOT path (a la [VSCode\_Julia\_portable/assets/install.sh at 689fcb996cff4cb858b88e37fe641f2b99816e8b · PetrKryslUCSD/VSCode\_Julia\_portable · GitHub](https://github.com/PetrKryslUCSD/VSCode_Julia_portable/blob/689fcb996cff4cb858b88e37fe641f2b99816e8b/assets/install.sh#L49), and [VSCode\_Julia\_portable/assets/install.sh at 689fcb996cff4cb858b88e37fe641f2b99816e8b · PetrKryslUCSD/VSCode\_Julia\_portable · GitHub](https://github.com/PetrKryslUCSD/VSCode_Julia_portable/blob/689fcb996cff4cb858b88e37fe641f2b99816e8b/assets/install.sh#L34)). And, voila, you have a “portable” Julia on your Mac. No toes have been stepped on in the process.

Yea, thanks I am sure this will work theoretically 😉 Since my Julia is now running without problems I‘ll let it for now.
