I've been having the same problem since last night when I replaced the default iTunes icon using CandyBar. I just reverted to the default icon and the problem seems to be gone.
Oh ok...
I used to use Candybar back in Tiger, but haven't been using it in Leopard. Can't remember changing the icon though, and it looks like the real thing... Hmm I'll install candybar 3 and see if I can fix it that way.
Hey that helped!
Though, I had to load up Candybar in demo mode (don't have a license,) change the icon on iTunes, apply, and then remove/apply again in order for it to work. Strange to say the least since the iTunes icon was default...
I'm glad that worked. Before I reverted to the original icon I took a look inside the iTunes package /contents/resources/ folder and there was a backup of the original icon put there by CandyBar. I suspect that may have been the problem but I can't imagine why.
I don't think CandyBar is the problem. I've been getting the message ever since the latest iTunes update...and I've never changed my iTunes icon with CandyBar.
System Preferences, Security, Firewall, allow all incoming connections.
I'm assuming that as it says "Mac OS normally determines which programs are allowed incoming connections.....) is safe.
iTunes is in that list, but by checking set access for specific services and allowing iTunes in the list to have incoming connections, I still got the "do you want to allow" dialogue every time.
This is with the latest (yesterday) iTunes update.
A temporary workaround is to disable sharing your music library in your iTunes preferences. This stops the pop-up. Hopefully someone will find a solution and/or Apple will release an update. I suggest dropping bug reports to Apple as they do not read these forums.
None of these have fixed mine yet. I've also tried disabling the fetching of album artwork, turning off my Express so there's no AirTunes, removing podcasts, etc.
I've been denying and so far everything is working.
Maybe to keep from seeing the popup, I'll just click Allow and have it running all the time in the background. The internet is full of trustworthy people and it won't hurt to enable incoming connections.
Unless we get some kind of explanation and if this connection is to be a permanent thing. This would be a BIG bug I would think.
I read in an Apple document (I'll try and link it tonight) that the setting you have it on automatically allows the programs that are bundled with the computer (so iTunes, iChat, iLife etc). You don't need to add those to "allow incoming connections", they are allowed by default.
Therefore, you keep the Firewall on the third setting (where you can set permissions for various programs), and only add 3rd party apps onto it. The Apple apps should all be fine.
I had iChat and iTunes on that list, got sick of it asking me to allow it every time, and searched the Apple info docs - one of them explained the situation better than I have 🙂 Took them off and checked the connections with Little Sniffer, and all was fine. It was allowing connections for iTunes and iChat - and blocking / allowing third party app connections as instructed to by the Firewall settings.
