Follow the steps below to solve Blank GUI issues on macOS High Sierra.
If the graphic user interface of your Waves plugins, SoundGrid Studio or StudioRack (V12 and higher) is blank after installing plugins on your macOS High Sierra computer, this may be because your Mac’s graphics card does not support Metal, which is required for plugins, SoundGrid Studio and StudioRack, V12 and above.
To verify whether that is indeed the cause of the behavior, check which Mac models support Metal. If your Mac does not support Metal, you will need to roll back your Waves plugins to V11, or roll back your SoundGrid Studio and StudioRack to the previous version which does not require Metal support.
