Since October 4th macOS builds are hanging -and failing- during Crystal’s install step (see [1](https://travis-ci.org/olbat/icu.cr/jobs/596330893),[2](https://travis-ci.org/olbat/libgen/builds/595704885)).

I can see this in your failing build:

```auto
Warning: Your Xcode (8.3.3) is outdated.
Please update to Xcode 9.2 (or delete it).
Xcode can be updated from the App Store.
Warning: A newer Command Line Tools release is available.
Update them from Software Update in the App Store.

```

Can you try to run your build on Xcode 9.2 with the following in your .travis.yml file?

`osx_image: xcode9.2`

I would even recommend using a newer image. You can look at your supported images here:

> **[Travis CI Documentation](https://docs.travis-ci.com/user/reference/osx/)**
>
> The macOS Build Environment

Let us know how it goes!

Nice catch, @dominic, I missed that!

In the light of this, the more concerning message is [Travis CI - Test and Deploy with Confidence](https://travis-ci.org/olbat/icu.cr/jobs/596330893#L3743-L3745:)

> ```
> Warning: You are using macOS 10.12.
> We (and Apple) do not provide support for this old version.
> You will encounter build failures with some formulae.
>

Which means that Homebrew has stopped providing newer bottles for OSX 10.12 and **@olbat needs to rather update to 10.13** i.e.

```yaml
osx_image: xcode9.4

```

(which is the default so they can omit the clause altogether)

Awesome, it worked!

Thanks a lot for your help on this 🙂
