### Upgrading OS X
Upgrading OS X can cause errors like the following:
- `dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.54.dylib`
- `configure: error: Cannot find libz`
Following an OS X upgrade it may be necessary to reinstall the Xcode Command Line Tools and `brew upgrade` all installed formula:
```bash
xcode-select --install
brew upgrade
```
