Error installing Nix in Mac with FileVaut encrypted volumes about ihp HOT 11 CLOSED

What macbook version are you using?

Can you try these steps (take from NixOS/nix#2925 (comment)):

sudo mkdir /System/Volumes/Data/opt/nix
sudo chown {your_user} /System/Volumes/Data/opt/nix
sudo sh -c "echo 'nix\tSystem/Volumes/Data/opt/nix' >> /etc/synthetic.conf"

Reboot mac. Then:

export NIX_IGNORE_SYMLINK_STORE=1
curl https://nixos.org/nix/install | sh     

After that, add the following to ~/.zprofile:

. ~/.nix-profile/etc/profile.d/nix.sh
export NIX_IGNORE_SYMLINK_STORE=1

I've just tried these steps on a clean 2018 macbook pro (where the above nix installation error message also appeared), and this fixed the problem.

This didn't work for me as is. I had to add the -L argument to curl. I guess the page moved? 🤷‍♂️

export NIX_IGNORE_SYMLINK_STORE=1
curl -L https://nixos.org/nix/install | sh

This issue has been finally fixed by nix. The macos install script has been updated to automatically resolve the problem here.

See NixOS/nix#4289

Just for completeness/confusion-avoidance, it'll still need to be released (either in 2.4, or backported to 2.3.x) before it'll work for standard installs. There are instructions in the PR head comment for using a test installer generated from it, which may be a tolerable stopgap (but no substitute for squeaking loudly about getting a new release cut? :)

Doesn't work on MacOS 11, the check looks to be insufficient as it tells me to upgrade to 10.x

What commands/approach did you try? And what's the error message?

11.0 is not supported, upgrade to 10.12.6 lol

Sorry, command got stripped somehow ...

FYI, I didn't try the above solution, but this blog post worked well for me (Macbook Pro 2017 (Pre-T2) Catalina with FileVault).
