Alternative to Cover Version visualizer in iTunes 12.6
Cover version works on iTunes! What you should do is to create a new directory ~/Library/iTunes/iTunes Plug-ins and put the Cover version file in there.


Quit iTunes
Go to Finder
Press Alt (OPTION) while selecting GO in the menu
Go to Library
Create iTunes directoy if it doesn't exist yet
Go into iTunes directory and create iTunes Plug-ins
Copy Cover Version in there and start iTunes
Now you can select Cover Version again (CMD +T)


I hope this will work for you ... I works for me in iTunes 12.7.2.58
