Holochain Install Issue on MacOS 15 Sequoia: Getting eDSRecordAlreadyExists when nix installer is trying to create User _nixbld1

[evomimic]

There is a known nix installer issue that surfaced when Apple staked out a few more UID's in their MacOS 15 Sequoia release. Details can be found here: NixOS/nix#10892.

This issue has been fixed in nix installer versions 2.24.6+, but it appears holochain installer is still wrapping an older version.

I ran into this issue trying to install holochain on my new MacBook and it took me a while (and a support ticket to nix) to get past it.

Here is a workaround that worked for me:

NIX_FIRST_BUILD_UID="351" bash <(curl https://holochain.github.io/holochain/setup.sh)

Best case would be a holochain installer script update that references a nix installer v2.24.6 or later.

But I know you guys are balancing a lot of priorities. So if that fix isn't forthcoming, an update to the Getting Started page with the workaround would save newbies frustration.

That's been in the back of my mind to do for a while, I will go update that script now!

PR to do the update here -> holochain/holochain#4655

All done! Thank you for reporting this, and glad you found a workaround in the meantime.

Is everything working for you now?

Thanks for jumping on this so quickly, @ThetaSinner !!!

I'm good.
