Music/iTunes library broken. How to restore from iPhone?
I just migrated from my old Mac Pro 2010 to a Mac studio (so no system experience beyond High Sierra). Several attempts with the Assistant eventually got everything over ... but. My iTunes/Music library was on an external drive that died a while ago. Everything is also on my iPhone but I can't figure out how to use it to repair the new Mac (studio Pro). Both are on my AppleID account. When I go the the store it lists my purchased music but there is no "Download" option. ( The transfer on Photos from phone to Mac went fine- it also had been corrupted) I'd like to delete the fragmented/broken version on the Mac and restore it with a complete version from my iPhone. Is that even possible? . Are there new security system steps I need to address, even though both are recognized as "me"
Thanks for any help/suggestions
Mac Studio, macOS 12.3
