firewallitunessettingssystem-prefs
Whenever I open iTunes, I get the standard OS X dialog, Do you want the application "iTunes.app" to accept incoming network connections?
Every time I click allow, but I am asked the same thing without fail the next time I open iTunes.
In the Advanced section of the Firewall tab of the Security System Preferences pane, I see that iTunes is in fact set to allow. Changing the firewall settings makes no difference.
Any ideas for how to get this setting to stick?
That's unusual because applications created by Apple should be automatically permitted access through the firewall. Have you modified iTunes (added plugins for example) in any way? You can check if iTunes' digital signature is valid with the following Terminal command:
codesign -vvv /Applications/iTunes.app/
You should get two lines back looking like those in the image below
If these don't match with what I have or even if they do, a reinstall of iTunes or removal of any plugins should fix it.
Use the following steps:
Signing the python application, using the instruction in the answer to this question, worked for me.

I looked at Am1rr3za's article, and eventually it just said to reinstall iTunes, which I did. That worked. Am1rr3za, post as an answer if you want the points. Otherwise, I'll accept this one.
