So I have still not got iMessages to work in El Capitan and I have to Log into iCloud every time I restart or it doesn’t work, but this is about iTunes.
After getting my iTunes back working, but losing all of my playlists and Metadata, I have been working on re-rating my tracks, and remaking my playlists.
What is interesting, and scary to me is as I rate more tracks, iTunes slows down more and more, and I am getting more and more beachballs. Basically I listen to a track and give it rating then skip to the next track, and often it starts playing the new track, but doesn’t show it in the interface for a while and I get the beachball for a bit before I can rate the next track. And as I rate more tracks and remake more playlists it gets worse.
I just hope once I am done (as I am only in B so far) that it doesn’t slow down to the speed of my old messed up Library. I thought the new clean library would just stay faster, but it seems to be getting slower the more work I do on it!
This is really scary as it shows that the slowdowns are indemic in iTunes code with large libraries and a large metadata collection.
It means Apple really needs to start over on iTunes and rewrite the code from the base up, but that is a scary prospect as it will likely break much of the functionality that exists (and they have already been losing more and more functionality over time), and create new issues for a while.
Honestly I just hate to have to put all the time into fixing my iTunes only to see it be slow and hard to use again.
