Apr 19, 2020 · I installed Sunflower sound drive long time ago. From System Preferences or Sound source list, 2 soundflower items are displayed. Since this sound source is not working well in Mac OS Catalina, and I have never used it as audio output, I need to remove them. I found that sound items were installed as extensions to Mac.
Swivel requires Windows XP or later, or Intel-based OS X 10.5 or later. If you are on Mac OS X 10.7 (Lion) or later, pick 64-bit. If you are not sure, pick 32-bit.
