Lookupd and iTunes

[tuartboy]

All of a sudden (no installs or changes) the lookupd process started eating up all my CPU cycles. I narrowed it down to iTunes and the second it launched, lookupd skyrockets in the activity monitor and holds a steady > 30% CPU percentage. I can't figure this one out as my OS X troubleshooting is limited to killing the plist, resetting PRAM, and repairing persmissions; none of which worked.

Edit:: I also flushed the lookupd cache which did not help either...

Ok, here's a quick followup and then I'm out the door for NYE:

I did a fresh install of iTunes and that killed the constant CPU usage issue. No idea why, but it worked. Then I started noticing a 5-10 sec burst of lookupd usage every once in a while. I timed this out to once a minute and realized that it likely coincided with my mail.app checking. I systematically disabled accounts and discovered that it was a plugin called httpmail that I use to check my old hotmail account that was causing the problem. I disabled the account and the CPU usage is gone for good now.

Hope this helps someone in the future.

Happy New Year!

Hi tuartboy - having exactly the same issue - (thanks istat nano widget!) - how would one go about doing a fresh install of itunes?

Wow, thread resurrection.

You can download a new copy of iTunes from http://www.apple.com/itunes/. I also suggest downloading AppZapper from http://appzapper.com/. You can delete applications in OS X by dragging them to the trash, but AppZapper goes a little further by checking what files outside the package the app uses and getting those too. Just a little cleaner delete and it's a free demo, so why not?

1. Open, install, and run AppZapper.
2. Drag iTunes onto AppZapper (or into Trash if you don't want to use AppZapper)
3. Finish the delete.
4. Open the iTunes dmg and drag it into your applications folder.
5. Done

As far as I know, this was the process I used. You can usually just drag the new app onto the old one and overwrite it, but I prefer to clean out plists and other config files just in case so I use AppZapper.

Best of luck.
