No manual relocate

Hi guys - Im struggling with this for few months and still same issue, cant figure it out.

When i got a new mac i changed everything to the new mac and most tracks worked fine but there are some missing. When I load it says missing file but when i check for missing files says all files exist. 

Is there a way for me to manually locate the files or change the path? Ive watched tutorials and when i right-click in files the option is not there. On the last version of Rekordbox... still same issue, cant manually select a path for a file? This is very frustrating...!
