Der AMPArtwork-Folder liegt unter ~/Library/Containers/com.apple.AMPArtworkAgent/Data/Documents/artwork und füllt sich durch die bloße Benutzung von der Music.app. Darin befinden sich alle Albumcover als Thumbnails. In meinem Fall waren das über 12000 Jpegs mit über 900 MB.
Der AMPArtwork-Agent sammelt diese Daten ein, den kann man in den Prozessen identifizieren. Der Artwork-Folder dient auch als Quelle für den Apple Screensaver „Album Artwork“: wer Apple Music nicht nutzt, für den ist auch dieser Screensaver nicht verfügbar. Der AMPArtwork-Ordner enthält auch Thumbnails von den in Music.app verwaltenden Musikvideos, Filmen und TV-Shows, bedeutet, es gibt auch Bilddaten, die nicht quadratisch sind und dann ein bisschen aus der Reihe fallen, positiv gesehen.
Die Basis ist von Moodboards entlehnt, mit ähnlichem Bildergebnis. Die wesentliche Änderung ist #MAX_IMAGES und #LAYOUT_SETTINGS um ein anderes Grid zu erzeugen. Der Messy-Faktor wird mit #RANDOM_POSITION gesteuert.
