iTunes keeps asking about incoming network connections Since I’ve upgraded to Mavericks (10.9, then 10.9.1), the system has been asking if iTunes (up to the current 11.1.5) should accept incoming network connections every time it launched it.

I’ve tried reinstalling the app, to no avail. Running the app on a fresh account (hence with default preferences and empty library — does it even need inbound connection by default?) doesn’t display the dialog.

I’ve tried removing the preferences file and the iTunes directory from the ~/Library folder, yet again with no result.

I’ve check the signature of the app with:

$ codesign -v /Applications/iTunes.app
/Applications/iTunes.app: a sealed resource is missing or invalid


It thus seems I have an app signature issue.

What should I try next?
I reinstalled iTunes again, and this time was successful.
