I use my external drive to store home videos etc for iTunes and now Apple TV+ but recently it seems to cause Apple TV+ on Mac won't open. I have reset library location back to default location BUT it still remembers where home video is saved because it still appear on Apple TV+. How do I reset it completely? Or make it forget previous location? I rather not keep restarting my Mac just to get Apple TV+ app to work. I cannot seem to find answer on Google and Google keeps thinking about hardware Apple TV not on Mac which make it very hard to Google exact hardware I am trying to solve.
