So, my tedious solution is to connect the old iBook and modern iMac wirelessly via
Finder -
Go - Connect to Server. They are then both controllable from each other.
Import a CD into iBook iTunes.
Then on iMac iTunes go to
File - Add to library. The navigate to the iBook's Home folder
User - Music - iTunes and select the album that was the CD.
That then imports to iMac iTunes (annoyingly without any apparent progress bar
)
As the iBook is also connected to the internet, it access and applies artist, album title and track information.
Only problem so far is not all the CDs come out at the same volume somewhere along the line
Good thoughto discover some music I'd completely forgotten about
