How do you know/change which iMac iTunes Match is syncing from?
I have two 27" iMacs, The first one is a 2012 later version and the second one is a 2020 version. I use itunes match to sync my music from the 2012 iMac because that's where all my music is stored. However, when I store music on the 2020 iMac (particularly music videos) I don't see it syncing with my other devices, especially Apple TV. I want to start using my 2020 iMac to sync music across my devices and no longer want the 2012 iMac to sync.
So I ask again... How do you know/change which iMac iTunes Match is syncing from?
