Not Functional
I have tried to get this app to work on my 2011 iMac i7 for an entire afternoon to no avail. I first tried to drag and drop a folder of files into the app but it doesn’t recognize folders. So you have to manually drag the actual files into the app. If your files are sorted by artis and album, any library over a few dozen albums would be incredibly tedious to process. The help files say you can drag and drop playlists, but i was never able to get the app to work with a playlist over a few songs. It would recognize the first few songs, then claim that the rest of the songs were 0 mb in size, and not even try to process them. Even when I drag and drop the actual files from a single album into the window, click on auto detect and wait for it to finish, then click on apply changes as the help file states, the app hangs and requires a force quit on 4 seperate attempts. I would give a zero if possible.
