The artifacts are available and include the PKG installers. This PR is not done (see description), but those should be functional already. Please let me know if you have any feedback!

Looks great! But, the artifacts are expired 😢 edit: nvm, they're here https://github.com/conda-forge/miniforge/actions/runs/7915666236 BTW bit of a bummer that they require admin to run 😢 that could just be an issue with the apple pkg installer though.

Check these ones: https://github.com/conda-forge/miniforge/actions/runs/7915666236

I don't think they require superuser per se, but maybe there's a bug. Let me know.

[psobolewskiPhD]

Yea I found the right artifacts, tried the mini forge-arm64 and it did require admin. I will try to test on my personal machine later where I have admin, but I can't on my work one.

So first, it doesn't wanna open because it's not signed and apple hates us.

I went into security settings and allowed it explicitly (required admin), so the dialog box got less scary:

It allowed me to install it just on my home directory

Failed the first time because I already have it installed

But it works now, after!

So I suppose it needs to be signed?

Thanks for working on this, @jaimergp!

[jaimergp]

Yes, the signing machinery is there in constructor (thanks napari!), we just need the Apple certificate from NumFocus.

[jaimergp]

Also, if you have feedback about the messaging, we can customize some steps.

Only suggestion is to maybe have something in there about pre-existing installations? But that's very minor, as the target audience for this probably does not have pre-existing installations.

as the target audience for this probably does not have pre-existing installations.

I think this is a fair first approximation.

However, I think we get many questions on this issue tracker where people have trouble installing miniforge when Miniconda or Anaconda is already installed (and to a lesser extent when miniforge or mambaforge is already installed).
