How can I recover a my iTunes library on my older MacBook Air?
Hello there, I have a 10 year old MacBook Air from which I was having issues sharing photos. To cut a long story short, all the photos are now on a pen drive and the lovely chaps that were dealing with it for me ended up putting a new operating system on the machine (Mac HD?). Nearly all of my iTunes library has disappeared since they did this, a gathering of 10 years worth of CDs that I had copied to it and a lot of albums I had bought from Amazon as well as iTunes. I have gone on to the Apple Music app on my Mac and gone through the process on the iTunes Store to check purchases, but as I said, a lot of what I had was either CDs that I had copied to it, or purchases from Amazon. Is there anyway I can find these? I am devastated, as I no longer have access to a lot of the CDs. I have seen some posts mention going onto the iTunes file, but I have no idea what that means, and when I look in Finder there is no mention of iTunes or music. I am fairly computer illiterate, so don't understand a lot of what is on other posts on here I'm afraid...
