Not able to update music
When I connect my iPhone 6 plus through USB on my MacBook Pro all my music appears, but i can no longer edit any information of the songs or even delete an unwanted song.
This all changed when I did a factory rest on my Mac.
Can anyone PLEASE tell me what i am doing wrong?
My iPhone 8.3 iTunes 12.2.27 and Mac OS X Yosemite are currently updated
