Did anyone fix this problem?.

Ran into this problem after installing a couple of add-ons. The problem is that the signature of the file was somehow corrupted. Rather than reinstall you can create a self-signed certificate and resign the xbmc.app:

1. Verify the signature of xbmc.app:

From TERMINAL type the following:

'codesign -vvv /Path/To/xbmc.app'

if the result includes the message 'a sealed resource is missing or invalid' then move on to step 2.

2. Create a Self Signed Certificate

- Open Applications > Utilities > Keychain Access.

- From the Keychain Access menu, choose Certificate Assistant > Create a Certificate.

- Fill in a name for the certificate. This name appears in the Keychain Access utility as the name of the certificate. This is also the name you will use when referencing this certificate.

- Choose Self Signed Root from the Type popup menu.

- Check the Let me override defaults checkbox.

- Choose Code Signing from the Certificate Type menu.
Click Continue.

Specify a serial number for the certificate. Any number will do as long as you have no other certificate with the same name and serial number.

- Fill in the information for the certificate.

- Accept the defaults for the rest of the dialogs.

3. Re-sign xbmc.app:

From TERMINAL type the following:

'codesign -s "NAME OF CERTIFICATE" -f /Path/To/xbmc.app'

4. Verify the signature of xbmc.app:

From TERMINAL type the following:

'codesign -vvv /Path/To/xbmc.app'

if the result includes the message 'satisfies its Designated Requirement' you are good - move on to step 5.

5. Delete and re-add xbmc.app to firewall exceptions (System Preferences)

You should no longer be prompted to allow incoming connections!

By the way, this same procedure will work for all your other apps including iTunes etc. Clearly not an XBMX issue.
If it works for you please add to my rep!!
