unwanted sound
Since I have upgraded to MacOS 11.7 and Safari 16.0, I experience undetected music (a rithm box is continuously playing and interferes with other sound sources like iTunes. How can I detect its source and remove it? Quitting Safari and removing history as wel as rebooting does not remove it.
After upgrading I got a warning that Garage Band was corrupted with the advice to remove it and install it again. I have done this but not yet installed as I never use this app.
