Sync music to iCloud
Hi.
I have 19GB of music on my MacBook Pro that I'd like moved off my device and onto iCloud. The Sync Library box is checked in Music/Preferences. Some of this music was originally saved on a PC before I got the Mac and then saved on the Mac. Thus, I can play this music on my Mac but, although I can see the music files on my iPhone X, I can't play them there. I can play the music downloaded off iTunes on both the Mac and iPhone. How can I get the music on the laptop off it and onto the cloud?
MacBook Pro 13″, macOS 11.6
