I want to move my iTunes library from an old Windows PC to my new Macbook Air (M1). I googled but find so many old out of date guides, can someone point me in the direction of a guide based on more recent iTunes builds and BigSur macOS? I don’t really use iTunes anymore and haven’t synced my phone with a computer for years but I want to bin the old laptop yet still ensure that I have all my old music and purchased music safe and accessible when needed. I’d also ideally like to have the main files on the MacBook but music files in a separate HD to save space on my MacBook.
