2022 MBA M2 Set-Up Questions

As long as you are signed in with your same Apple ID on the new Mac, the iTunes and iBooks content will be available to directly download (or stream) on your new Mac. You will need to Authorize the new Mac as one of the 5 available authorizations (Music or TV app, Account menu > Authorizations > Authorize this Computer). If you use iCloud to sync your Photos, those will also download.

However, if you want to transfer them manually (e.g. with an external drive or flash drive), you will need to find them on your old computer.

Music/TV/Movies are in Music > iTunes > iTunes Media, Photos are in Pictures > iPhoto Library, etc. On your new Mac, items can be imported in their respective apps using File menu > Import. Note that for DRM-protected content (most media including books), you'll still need the new Mac to be Authorized using the same Apple ID originally used to purchase the content.

Depending on the MacOS version, you may have iPhotos and not the Photos app, in that case be aware that the import will take some time to complete (most of it is the processing step which includes face detection in all the photos, that can take a few days to complete but runs in the background).
