Hello,  
I have been trying to install Julia into a MacOS, which I am not yet familiar with. As advided by the installation page, I tried:

```julia-auto
curl -fsSL https://install.julialang.org | sh

```

I have added IJulia Package. But upon calling notebook(), I could not find the Julia kernel in the Jupyter notebook(). I would really appreciate any insights on how to get the notebook to recognize the Julia kernel.  
Thanks and regards!

Sounds like it might be related to a change in the latest release: [Fix macOS default Jupyter data directory to prioritize Application Su… by arafune · Pull Request #1238 · JuliaLang/IJulia.jl · GitHub](https://github.com/JuliaLang/IJulia.jl/pull/1238)

What does `jupyter --data-dir` show on your system?

Thanks for the reply.

```julia-auto
Jupyter --data-dir

```

results in:

```julia-auto
/Users/lab123/Library/Jupyter

```

The first thing I try when this happens to to type

```julia-auto
(@v1.12) pkg> build IJulia

```

in Pkg. That can clean up a lot of kernel confusion.

Ok, that’s most likely caused by IJulia then because it will now install kernels in `~/Library/Application Support/Jupyter`. Sorry about that, I’ll see if we can get a fix in the next week or two. In the meantime, a simple workaround would be to go back to IJulia 1.34.0.

BTW, what version of Jupyter do you have?

Apologies for the late reply. When I run:  
lab123@MacBook-Pro ~ % jupyter --version

I get:

```julia-auto
Selected Jupyter core packages...
IPython : 8.18.1
ipykernel : not installed
ipywidgets : not installed
jupyter_client : 8.6.3
jupyter_core : 5.8.1
jupyter_server : 2.17.0
jupyterlab : not installed
nbclient : 0.10.2
nbconvert : 7.17.0
nbformat : 5.10.4
notebook : not installed
qtconsole : not installed
traitlets : 5.14.3

```

However, If I run in Julia:

```julia-auto
using IJulia
notebook()

```

The version is: 7.5.3
