iTunes 11.3 freezing when refreshing podcasts

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

The title of the Console window should be All Messages. If it isn't, select

SYSTEM LOG QUERIES ▹ All Messages

from the log list on the left. If you don't see that list, select

View ▹ Show Log List

from the menu bar at the top of the screen.Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please don't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name, may appear in the log. Anonymize before posting.

I don't know if this applies but see this thread I started about v11.2: Podcast List view == Massive Memory Leak?

My Mac Pro iTunes 11.3 freezes and is unable to download any podcasts. I've force quit many times, but the same problem continues. I can't download any new podcasts. It's very frustrating.

I only know this workaround: after launching the podcast update, switch asap to another list view (i.e. "Music" or "Applications") and don't come back to "Podcast" view until the update is completed…

I know this is for mac users, but I was having a similar issue with my Win7 64. I actually uninstalled quicktime 7 and it started working again. Now, when I update my podcasts and mark as played or not played, I get a hang up for about 30 seconds and then the program works again. Good Luck!

I get similar console messages, trying to do anything in the podcast tab and itunes uses 100%cpu and slows to a crawl...

Back up all data.

As a test, please move the iTunes library folder from the Music folder (or wherever you keep it in your home folder) to the Desktop. If you've moved the library folder to another volume, unmount the volume.

Quit and relaunch the application. It may prompt you to create a new library, or to select an existing one. Create a new one and import a few tracks. Test.

After testing, quit again and put the original library back where it was, replacing the test library. Post your results.

I am having the same problem, so I'm currently trying your suggestion, and am moving my library to the desktop. It is 253 GB big, and I have over 22,000 podcasts. I'm hoping to trim down the podcasts, but it is so slow it is currently impossible. It took me 6 hours to delete 98 podcasts, each 5 minutes long. Refreshing takes too long also.

I have the exact same problem. If this keeps up I am going to stop updating iTunes. (e.g. A couple of updates ago everything stopped working also. While it took about an hour to perform, fortunately someone posted a fix that worked. What has happened to Apple's legendary software quality control? 😟 Extremely frustrating.)

As an attempt to fix the problem I rebooted my computer. Also uninstalled iTunes, rebooted, and re-installed iTunes. However, nothing has worked.
