### Troubleshooting when building FF ### Troubleshooting when building FF on Mac
#### Black screen after FF Build
As of Jan. 2019 there is a known [bug](https://bugzilla.mozilla.org/show_bug.cgi?id=1493330) that will cause an entirely black screen when running the nightly build of firefox built with the **MacOSX SDK version 10.14.**
The easiest fix right now is downgrading your MacOSX SDK.
To do so:
1) Go to [this repo](https://github.com/phracker/MacOSX-SDKs) and install any **SDK version < 10.14** (e.g. 10.13 works fine)
2) In the `juggler/firefox` folder:
```bash
echo "ac_add_options --with-macos-sdk=path/to/sdk" >> .mozconfig
# your SDK might be located at
# /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/
```
3) run `./mach build` again
#### Missing headers in /usr/include
On MacOS 10.14 (Mojave) you might run into issues when building FF. On MacOS 10.14 (Mojave) you might run into issues when building FF.
