My wife's iMac is where we store all our Music ripped from CDs, downloaded etc. Since the Catalina upgrade the new Music app just eats memory killing everything else - this morning it was up to 57GB according to the Activity Monitor, and it just grows if you leave it - seems like a major memory leak
to me.
iMac Line (2012 and Later)
It is trying to upload all of the artwork. You might notice in the lower left corner it says loading artwork. This process can take a couple of days depending on how much music you have. I would just quit the application whenever you notice that the memory usage is getting high in the activity monitor. Hopefully this task will complete and you won't lose any album art like I did.
Thanks - whatever it was trying to do it should not be eating memory like that - that is a flaw in the development. We did notice we had some artwork missing, I'll check if it's still there.
why does Apple Music eat up memory
