Q: Why when I transferred my music from my iPhone to my Mac are many of the albums i purchased incomplete?

Hi Makki28,

I'm sorry to hear you are having this issue with your iPhone. If you are having issues with incomplete transfers of your purchases from your iPhone to iTunes on your Mac, you may want to double check that you are following the steps as outlined in the following article:

Re-download or transfer your iTunes Store purchases from an iPhone, iPad or iPod to a computer - Apple Support

If you are still having incomplete albums, you may also want to try directly redownloading the purchases from within iTunes, as noted in this article:

Download past purchases - Apple Support

Regards,
