I have a 500GB SSD on my MBP and am always actively looking to keep it as clean as possible. I have moved most of my documents and files onto my NAS (Synology) and starting last year, I moved my iTunes library there as well. I use the NAS' iTunes server to broadcast music to my computer, devices, etc. Lately I have noticed that no matter what I do, my SSD's space is still slowly decreasing, so I downloaded DaisyDisk and found the culprit - I have 41GB of music on my NAS, but an Album Artwork Cache of 34GB on my MBP! There are folders being created on my computer on an almost daily basis. Is there a way to make this stop? I'd almost consider just stopping using iTunes and stream off my NAS with Synology's Audio Station (I don't really use iTunes for much of anything else except for buying music), but this is just crazy. Anybody have any thoughts or suggestions?
