> On macOS (tested on 10.14.3), a fair number of plugins now seem to have problems with their UI. Melda Production is a good example of some free ones. The UI appears black. They work in an older version of JUCE. I’m not sure of the exact one but Waveform 9 works and was built with this version of JUCE [8deef0b](https://github.com/julianstorer/JUCE/tree/8deef0b4bc14b41a14e19d1e8e11d57aca3d6875)
