Monday 24th of September Apple released Mac OS 10.14 aka MOJAVE.
Before jumping into this new version and being tempted to enjoy the new dark mode on your Macs, be aware that it could cause issue with Daws & Plugins.
Audio products manufacturers will either report having no issue with Mojave and their products or to have found some problems and being working on it ( I know that Soundtoys have already report some issues and that they are working on an update ).
When some companies will perform correct testing prior to public Mac OS release while the beta are going on, many others won’t and they will learn about issue in time via end users feedback.
So keep it on hold for now if you depend on your Mac for audio production and if you can’t refrain to jump into “Dark Mode”, just be sure to back-up your entire Mac using reliable app like Carbon Copy Cloner.
Next to that, be aware that not all the Macs are eligible for Mojave upgrade and that it will likely depends on hardware specs. You’ll find more about this here :
