Could not write domain com.apple.universalaccess during fresh nix-darwin install on a flake

[aspauldingcode]

My custom config is
https://github.com/aspauldingcode/.dotfiles
and the first rebuild to install nix-darwin and build with the project flake fails with the command:

nix run --extra-experimental-features "nix-command flakes" nix-darwin -- switch --flake ~/.dotfiles#NIXY

My darwin-defaults.nix:
https://github.com/aspauldingcode/.dotfiles/blob/766f3b87cb6782e932e60a7a2be8e837c7d5ca40/system/NIXY/modules/darwin-defaults.nix#L88

which contains
system.defaults.universalaccess = {
mouseDriverCursorSize = 1.2;
reduceMotion = true;
reduceTransparency = true;
};

which after commenting out, it will work and then I can add it back it will work.

Why does this fail initially?

Could you post the error when it fails? One common issue is that setting any of the universal access settings requires you to give full disk access to the terminal you're using via System Settings > Privacy & Security > Full Disk Access.

This fixed the issue for me.

That might take me some time..
I don't think I can reset my laptop until the end of the semester for college.

But, I will get back to you if I don't forget.

Is there a command that can solve this?
I really don't want to have to manually click sh*t on macOS to set this up

I got the perfect idea - Throw an error or warning message when this fails to compile based on this permissions issue specific setting!
