Nix: Installing on macOS Mojave fails

Created on 21 Jun 2018 · 37Comments · Source: NixOS/nix

When trying to install on macOS Mojave Beta, doing curl https://nixos.org/nix/install | sh, the install fails immediately after creating all the users with the following message:

This is after I uninstalled Nix and upgraded from High Sierra. How can I fix this?

The backport is ready now, 18.03 should be compatible since https://hydra.nixos.org/eval/1475530 and the channel has already updated.

@edolstra Everything should be ready, but it's probably fine to wait for a release with actual content (like https://github.com/NixOS/nix/pull/2371? 😄) since Mojave is probably still in beta for a while longer.

Did you remove the nixbld users after uninstall?

I have just removed all the users using sudo sysadminctl -deleteUser nixbldX and tried the install again, the same error persists:

@bemeurer Does /usr/lib/system/libsystem_network.dylib exist on 10.14? If not we'll have to update our Libsystem definition in nixpkgs.

LnL7 on 21 Jun 2018

@LnL7 It does not, only libsystem_networkextension.dylib exists

mia:~ bemeurer$ ls /usr/lib/system/ | grep -i network
libsystem_networkextension.dylib

lovesegfault on 21 Jun 2018

So is that the only removed lib? For instance, this file has all of the ones we expect:

matthewbauer on 21 Jun 2018

Yeah, similar to libsystem_coretls with 10.13 but that might not be the only problem ofcorse.

LnL7 on 21 Jun 2018

Using this hacked-together script I checked that only the file in question seems to be missing

@bemeurer Thanks for the information.

I made a tarball using https://github.com/LnL7/nixpkgs/commit/edfb283c16be021fbba0306193eb0e421ba5553c, it would be great if somebody could give that a try. Otherwise I'll look into setting up a vm.

@LnL7 I have downgraded back to High Sierra since the Mojave beta is really broken and I needed to work. I can try setting up a VM as well.

It's pretty obvious that this is a problem of compatibility with some system libraries that have disappeared, my only concern is how can I fix this if I can't even perform a nix-channel --update.

jbddc on 27 Jun 2018

@jbddc Is that using my tarball? If so you'll also have to use my nixpkgs branch to build packages, but that means there are no caches yet.

I'm pretty sure we'll also need to build a new bootstrap tarball, then we can push it to a wip branch or staging to start making compatible binaries with hydra.

The "right" way to fix this is to reinstall Nix (with ALLOW_PREEXISTING_INSTALLATION to avoid uninstalling Nix).

I'm a nix noob, but using @LnL7 tar's and nixpkgs (via nix-env -f /path/to/local/repo) works for me as far I can test it. I would love to provide some feedback & my testability for macOS Mojave 10.14

I got some additional failures on the latest public beta:

Undefined symbols for architecture x86_64:
  "___cVersionNumber", referenced from:
     -reexported_symbols_list command line option
  "___cVersionString", referenced from:

ld: symbol(s) not found for architecture x86_64

Removing these lines from pkgs/os-specific/darwin/apple-source-releases/Libsystem/system_c_symbols and pkgs/os-specific/darwin/apple-source-releases/Libsystem/system_kernel_symbols seems to get me a bit further, but I'm still mid-build so I'm not sure if that breaks the world, yet.

EDIT: Going to try https://github.com/LnL7/nixpkgs/commit/5024e4aa39d6d2ddfe52ee481f7a1f728d5b8d1e in my local checkout before I go deleting external symbols in earnest. Also downloading the XCode beta, just in case.

EDIT2: Still got the undefined symbol errors, so I've got a build going with those deleted. Fingers crossed.

EDIT3: Got through a basic build without any obvious issues. Rebuilding my full environment now.

Since this is apparently still a bit in flux we should probably wait a bit longer before adding changes to nixpkgs.

Am I using the repository in a wrong way?

MaxDaten on 11 Jul 2018

Finally got through a build with no substitutions. I keep getting unexpected end-of-file when darwin-rebuild goes to download nix-cache-info, but I have no idea how to troubleshoot that other than to try other substituters (cache.nixos and the reflex-frp one both give me the error, so I’m a bit stuck on that one).

jhenahan on 11 Jul 2018

@jhenahan So what was that undefined symbols issue? Did you manage to resolve it?

@LnL7 I don’t think this is in flux by now, I don’t think that Apple will be breaking anything else dramatically after the public betas are out. What do we lose by merging the fix into nixpkgs?

kirelagin on 11 Jul 2018

@kirelagin Removing the undefined symbols from those files seems to have done the trick. My entire config built with substitute = false to get around the nix-cache-info issue, though that seems to be fine, now, so that may just have been a hiccup on cache.nixos.org. Now I just have to wait for the Emacs team to figure out whatever weirdness Mojave introduced that breaks the GUI and I'll be golden! :)

Happy to push a PR with those changes if I can get confirmation that removing them won't have weird consequences for users on older versions of macOS.

jhenahan on 12 Jul 2018

After using @LnL7's tarball, I'm still getting this error:

There is still one dynamic library that has been moved/removed in Mojave, I believe.

After using @LnL7's tarball, I'm still getting this error: ...

@jbdd:

You’ll have to make sure that your NIX_PATH points to a nixpkgs checkout with the change, too, otherwise you’ll pull in the broken Libsystem. I just use a local nixpkgs repo with those changes cherry picked in.

jhenahan on 18 Jul 2018

@jbddc I don't know if this is a good choice. I just run sudo rm -rf (hash)--Libsystem-osx-10.11.6 and everything is going well till now...

@AurevoirXavier yeah that kinda worked. Thanks!

jbddc on 22 Jul 2018

Just as a gentle reminder: now that the necessary changes (https://github.com/NixOS/nixpkgs/issues/42719) have been merged to master in nixpkgs, what needs to be done to fix the Mac installer? Is it just cutting a new release of Nix, and if so, is there a specific way to trigger that? Or at least, add this to some list of things that will trigger it once it weighs enough?

qolii on 22 Aug 2018

Well, Nix releases are currently built from the 18.03 branch, so it's not enough to have the fix in master. Is the fix safe to cherry-pick in 18.03?

edolstra on 22 Aug 2018

FYI the latest binary tarball + installer script are at https://hydra.nixos.org/job/nix/master/binaryTarball.x86_64-darwin/latest and https://hydra.nixos.org/job/nix/master/installerScript/latest.

edolstra on 22 Aug 2018

I'm still running some builds to test the 18.03 backport just to be sure, but once those are finished we should be good to go.

For the non-nix experts like me, this is how I got it installing (in a clean system), from @edolstra's tarball:

$ wget https://hydra.nixos.org/build/80108588/download/1/nix-2.1pre6381_c651b7bd-x86_64-darwin.tar.bz2
$ gunzip -c nix-2.1pre6381_c651b7bd-x86_64-darwin.tar.bz2 | tar xopf -
$ rm -r nix-2.1pre6381_c651b7bd-x86_64-darwin/store/yvkvyvc36l2dmwl22vajc8bdg7fv3p6b-Libsystem-osx-10.11.6
$ nix-2.1pre6381_c651b7bd-x86_64-darwin && ./install

I was then finally able to run nix-shell -p nix-info --run "nix-info -m" after.

I'm sure there's probably something I need in Libsystem-osx-10.11.6, but at least this gets me to the next step.

The backport is ready now, 18.03 should be compatible since https://hydra.nixos.org/eval/1475530 and the channel has already updated.

I think this can be closed now.

@LnL7 Has the updates to fix this issue been released? I'm still experiencing this issue with the latest release of Mojave 10.14

@vai0 Try reinstall nix after upgrading from high serria.

@AurevoirXavier Didn't work :/. My eventual solution was to delete all references to *Libsystem-osx-10.11.6* in /nix/store. Not sure if this will cause problems later down the road.

Now you have broken store paths, and nix-store --verify --repair will either fail or restore the problem. Nix 2.1 with a reasonably recent nixpkgs channel will work.

@vai0 But you dont have to do that. This problem was fixed since last two updates release. And reinstalling works for me.

Problem solved. I was pinning the nixpkgs in my project, thanks!
