iTunes won't open after updating to 12.3.1

Hi I have OSX 10.11.1 running and I updated my iTunes to 12.3.1. Now all I get is the spinning beach ball when i try to start iTunes. I did a force quit and rebooted but the same thing is happening. I have a huge music library so I thought maybe it was doing some kind of update by after a half hour iTunes is still got the spinning beach ball. Any help would be appreciated.

iMac (27-inch Mid 2011), OS X Yosemite (10.10)

Thanks again for the fix - especially the link to 12.3.0, which Apple inexplicably seems to want to make hard to find.


Living with this for a few days, I've determined that the delay clicking between tracks is actually about 25 seconds not 15, but at least I can sync my iPhone 6S now. I'll only be using iTunes for syncing and library management, and only because I have to. For day to day music listening I'm using Swinsian. It's super snappy, even with huge libraries, and it uses the iTunes database, so no worries about file management or migrating to something new. No delays whatsoever. Album art in a resizable window. It even does bitrate switching automatically. And they have amazing personal support.

Any computer in my life that doesn't have to be upgraded will stay at iTunes 11.4 now, which still works fine with exactly the same library that makes 12.3.0 crawl. Swinsian for playback.

Today I updated my iMac to OS X 10.11.2, in the hope that this might bring a solution to the problem plaguing us here. No luck. iTunes is just as sluggish with the new El Capitan version. My suspicion is that there is some problem updating the iTunes database, for after each change in iTunes (e.g. editing the album name or composer), I see that the timestamps on the iTunes Library.itl and .xml files are changed. And these updates take 5-10 minutes (with rotating beachball and iTunes reported as 'Not responding') each time.


The program is unusable.


I realise that Apple does not officially follow this forum (and have reported the problem over the Feedback path). I am usually a pretty patient chap but, after being unable to use iTunes since the end of October (luckily I have a Sonos system too and so can listen to my music without iTunes - that is also why I haven't reverted to an earlier version), I really expect some action or, at least, an explanation why the correction is taking so long.


Come on, Apple. Many users are suffering from this problem. DO SOMETHING!

One further remark: while I was struggling along slowly just now (and iTunes was hanging), a message I haven't see often appeared on the screen:User uploaded file

I wasn't doing anything (explicitly) with the iTunes Store. I suppose something was going on in the background and am pondering now whether that is somehow connected with the problem discussed in this (already 8 page long) thread. Or was this just some normal background access to the Store which was disturbed by iTunes hanging? I have only a slow Internet connection, wireless - no landline, and wonder whether fellow sufferers have a similar environment.

Haven't had this message, but I reverted to 12.3. I did update OS X. For some reason, when I did the other OS update, App Store updated iTunes again, even though I didn't click on the update button. iTunes 12.3.1 wasn't as bad as when it first emerged, but even when clicking on a new song, the ball would spin for half a minute or more and Activity Monitor showed iTunes as using 100+% of CPU. So I reverted again, and all is well.


FYI, I have a 50 mbps Internet connection.

On my Macs with iTunes 11.4, all is well, if maybe a tad sluggish. On the one Mac running El Capitan and 12.3.0, working but insanely slow. (12.3.1 was totally non-functional, but the fixes in this post using Terminal saved the day and got me back to 12.3.0)


One short term solution - just use iTunes for file management. For day to day playback, use Swinsian. It's unbelievably snappy, and you can have it scan the iTunes library on startup so it's always synced. Automatic bit rate switching as well.
