Hi! I’m trying to set up julia on my older Intel Macbook running macOS High Sierra (10.13.6).

My julia version is:

```julia
Julia Version 1.8.1
Commit afb6c60d69a (2022-09-06 15:09 UTC)
Platform Info:
  OS: macOS (x86_64-apple-darwin21.4.0)
  CPU: 4 × Intel(R) Core(TM) i5-2435M CPU @ 2.40GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-13.0.1 (ORCJIT, sandybridge)
  Threads: 1 on 4 virtual cores

```

I downloaded it using the standard .dmg package on the julia website.

The error I’m getting when trying to precomplie Plots is the following:

```julia

Any ideas?

Thank you for the help!

Unfortunately that’s a very unhelpful error message coming from your operating system (julia has no control whatsoever over that). I’d note that macOS 12 provides more descriptive error messages when you aren’t able to load a shared library, but older versions are very economic with details.

> [@jeffzwe](#):

I’d have suggested to do something like

> [@Failing to precompile Plots due to LoadError](https://discourse.julialang.org/t/failing-to-precompile-plots-due-to-loaderror/77232/6):
>
> Try this: ]add https://github.com/giordano/DependencyWalker.jl using Plots # this will result in an error, it's ok using DependencyWalker Library(raw"C:\Users\frpa8185\.julia\artifacts\ecb81e6429c089c1da802644fae337754832d534\bin\avcodec-58.dll") The last command should show which library can’t be found.

using

```julia
Library("/Users/jeffreyzweidler/.julia/artifacts/c759795325eba6523fb1157b582551d4250575e1/lib/libavdevice.58.13.100.dylib")

```

as last line, but honestly I never used `DependencyWalker` on macOS and I don’t know if it’ll work (especially with frameworks involved). You can give it a try, but don’t expect too much. _ **NOTE** _: to be absolutely crystal clear, since this is a somewhat common misconception, `DependencyWalker` is a _ **debugging tool** _, it _may_ be able to tell you what’s the missing library, it will _ **not** _ solve any issue.

If `DependencyWalker` doesn’t help, you’ll have to start julia with `dtrace`, try to run `using Plots` and have a look at `dtrace` output to see what library can’t be found.

Again, there is is relatively little we can do about this, it’s your operating system that is withholding information from you.

The failing job logs (4h ago) are [here](https://github.com/JuliaPlots/Plots.jl/actions/runs/3141440502/jobs/5105742651).

`CI` was running fine 20h ago [see here](https://github.com/JuliaPlots/Plots.jl/actions/runs/3136837202/jobs/5094245833).

Weird, manifests are identical.

Apparently I don’t have the file

```julia
libavdevice.58.13.100.dylib

```

And therefore it also cannot be found… I’ve tried reinstalling the packages and also julia itself but this one keeps missing…

Oh, well, that’s a different error. Delete the directory `/Users/runner/.julia/artifacts/c759795325eba6523fb1157b582551d4250575e1` and try to reuse `Plots`. Uninstalling the package won’t actually remove it from disk until it’s garbage collected.

Okay so I’ve resolved the issue with FFMPEG and got it to precompile.  
But now I’m running into issues with GR\_jll and I’m getting identical error messages as this [thread](https://github.com/jheinen/GR.jl/issues/384). Sadly this issue hasnt been resolved in the thread.

Below the new error message:

I presume you made sure you have the file `/Users/jeffreyzweidler/.julia/artifacts/a0db4e704fd0da4298744f012883535d351fa170/lib/QtConcurrent.framework/Versions/5/QtConcurrent.dylib` in place?

Well I have an executable in place called QtConcurrent but no file called QtConcurrent.dylib … But no matter if I delete the folder `a0db4e704fd0da4298744f012883535d351fa170` and reinstall it the file does not appear…

@jeffzwe , can you please provide `Plots`, `GR`, and `GR_jll` versions (`pkg> status -m`).

Also, if you could try downgrading to `Plots@1.34.2`, and try again.

Wait, I think I have the answer to that: judging by

it appears Qt5 requires macOS 10.14, and you have 10.13. @barche is that correct?

Okay so I’ve installed Plots version 1.34.2 and I’m still getting the same errors…  
Plots v1.34.2  
GR v0.68.0

Thanks, so we can exclude the GR `0.68 -> 0.69` transition, for which we have issues on `windows`.

As mentioned in Slack (and in the pub) that’s a _different_ error than what is being reported here, which [I believe](https://discourse.julialang.org/t/failing-to-precompile-plots-due-to-loaderror-mac-edition/87911/12) is due to @jeffzwe using an old version of macOS. Your problem should have been fixed by [[FFMPEG] Set compat of PCRE2 by giordano · Pull Request #5594 · JuliaPackaging/Yggdrasil · GitHub](https://github.com/JuliaPackaging/Yggdrasil/pull/5594) and [[Glib] Fix compat of PCRE2 by giordano · Pull Request #5595 · JuliaPackaging/Yggdrasil · GitHub](https://github.com/JuliaPackaging/Yggdrasil/pull/5595).

Okay so I take we concluded on my version of macOS being too old. Is that correct?

In that case just wanted to say thank you for your time and effort! 😃

Yes, this is correct and more strict than needed because of cross-compilation (see [PR comment here](https://github.com/JuliaPackaging/Yggdrasil/pull/5598#issuecomment-1261824598)). I can’t test because I don’t have an older macOS, but one workaround at the end-user level could be to install the official Qt and then point to it using an Overrides.toml. This is my `~/.julia/artifacts/Overrides.toml` for Qt5 installed through homebrew:

```toml
[ea2cea3b-5b76-57ae-a6ef-0a8af62496e1]
Qt5Base = "/usr/local/opt/qt5"

[c6373c32-5b88-5913-90f5-31d7686b42da]
Qt5Declarative = "/usr/local/opt/qt5"

[3af4ccab-a251-578e-a514-ea85a0ba79ee]
Qt5Svg = "/usr/local/opt/qt5"

I’m receiving this error as well. I’m new to Julia and am having a little trouble understanding what to do to creating a work around.

On what version of macOS is this? Normally the latest Qt5 JLLs have been recompiled with the least strict requirement for Qt5.
