Color Well is gone from Audio Midi Setup device dialog boxes
I don't know what has happened, but my Mac min running High Sierra has developed some kind of an issue with Audio Midi Setup. The problem is that in the MIDI device screen, all of the icons have been changed to random colors with white text for the device names... which is unfortunate since it gave several of the icons white backgrounds. If I double click on an icon to edit it, the color well which used to allow you to change the color of the background is no longer present. Is there any way I can fix the colors of these icons? I tried poking around in the Audio Midi Setup prefs file, but I can't figure out how MIDI device info is stored in it.
