App Update - Apple ID
I need to update GarageBand to open new projects that were sent to me from a newer version. When I go to update it though, it's saying it can't because it was purchased/dowloaded with a different Apple ID. I have used the same Apple ID with all of my apple electronics though and I've only ever had one so that literally isn't possible. What should I do?
MacBook Pro 13″, macOS 10.12
