It seems that enabling Home Sharing and/or hooking up my iPhone's Remote to iTunes causes Mac OS X Snow Leopard's firewall to freak out and keep nagging every time I launch iTunes to ask if I'd like it to accept incoming connections. If I turn off Home Sharing and forget all Remotes, the nag dialog no longer comes up. I could also disable the firewall, but I think that's a silly thing to do.

iTunes is already in the firewall whitelist, so the only thing I know that could cause Mac OS X to nag is a bad application bundle code signature. I checked with this Terminal command:

$ codesign -vvv /Applications/iTunes.app/

And sure enough, this is what it outputs:

/Applications/iTunes.app/: a sealed resource is missing or invalid
/Applications/iTunes.app/Contents/Resources/English.lproj/AutofillSettings.nib/objects.xib: resource added
/Applications/iTunes.app/Contents/Resources/English.lproj/iTunesDJSettings.nib/objects.xib: resource added
/Applications/iTunes.app/Contents/Resources/English.lproj/MobilePhonePrefs.nib/objects.xib: resource added
/Applications/iTunes.app/Contents/Resources/English.lproj/MobilePhoneSetup.nib/objects.xib: resource added
/Applications/iTunes.app/Contents/Resources/English.lproj/UniversalAccess.nib/objects.xib: resource added

I've tried reinstalling iTunes as suggested by this answer, but Mac OS X still nags about incoming connections and the exact same output is generated when I run the above command again.

On my PC, Windows Firewall has never nagged whenever I turn on Home Sharing and hook up Remote on my iPhone. Both computers use iTunes 9.2.1. My Mac runs Mac OS X 10.6.4.

Is there anything special I need to do that I might have missed? Or how do I resolve the issue?

EDIT: I've updated to iTunes 10, but the nags on my Mac are still there and only go away if I turn off Home Sharing and Remote.

EDIT 2: I've updated to Remote 2.0 on my iPhone, but the firewall nags are persisting. Has anyone else had this firewall issue at all?

While updating to iTunes 10.1 and Remote 2.1 alone didn't get rid of the nags, I think they did indeed change something, because I just carried out the following and it looks like the nags are gone (for good?):

  1. Removed Remote.app from iPhone
  2. iTunes > Preferences > Devices > Forget All Remotes
  3. Quit iTunes
  4. System Preferences > Security > Firewall, remove iTunes from list of applications
  5. Started iTunes
  6. Reinstalled Remote.app
  7. Coupled iPhone with iTunes
  8. Restarted iTunes

I guess the Mac OS X firewall finally figured that iTunes was still iTunes, whether or not I shared my library or linked to any Remotes.

Or my Mac simply wanted to give me a New Year's surprise.
