My iMac is no longer sync'ing with Match properly - playlists created in it will not sync to my other three devices. It used to work fine. Now the cloud icon next to the MUSIC list in Library has grey lines across it that are moving constantly?????? As though it's trying to sync with iCloud or something.....but updating Match or even turning it off then on has had no effect. Match is working fine with my MacBook, ipad mini and phone, just not iMac. Match just renewed for another year, maybe it messed up somehow??
iMac, OS X Mountain Lion (10.8.3)
