"iTunes.app" to accept incoming network connections?

"It's probably easiest to reinstall iTunes.

If the firewall does not remember your choice, then the digital signature (Code Signing) of iTunes is broken. By default, the OS X firewall accepts any software that was signed by Apple without even asking you. So: it should not have asked you. And once asked, it should be able to remember, based on the digital signature. A broken signature (for example caused by changing the contents of the iTunes.app package) will prevent all this.

(Did you by any chance manually change the iTunes icon the application somehow? Or did you install some plugins?)

You can validate the signature of your iTunes by copying the first line and paste it in Terminal:

codesign -vvv /Applications/iTunes.app/

/Applications/iTunes.app/: valid on disk
/Applications/iTunes.app/: satisfies its Designated Requirement

(More details at If Mac code signing is tampered with, what might fail?)"

"Just wanted to report that I faced a similar problem after updating iTunes with the Apple Updater and the solution suggested here worked. Go into the iTunes package and delete all of the files that this terminal command flags as a ""resource added"":

$ codesign -vvv /Applications/iTunes.app/

When you rerun the terminal command, it will indicate that iTunes.app now ""satisfies its Designated Requirement"" and the annoying popup should go away.

Note that I don't have any deep understand of why any of this works. Seems like Apple broke something minor in their last software update and the firewall noticed. For any power-Googlers with little experience in these things, make sure you always backup your files before mucking about with anything like this--for your work, those preferences might be important."

I had this in iTunes 9.0 on Snow Leopard. It went away when I upgraded to 9.0.1. (Probably because of the reinstall, as that worked for you.)

Sometimes it's not related to a codesign or signature validation as much as you're simply using Home Sharing in your iTunes which prompts you if you want to allow incoming connections.
