Just bought a new M2 Mac mini and transferred my old iMac content over onto it. I forgot what a mess it is to get Apple TV, Music, iphone App Store, Mac App Store and iCloud accounts all working when you have a legacy iTunes account which differs from your me.com/iCloud account. I use to have a US iTunes account with some movies on it I have given up on all those downloads, just can't merge anything it's a real mess.
