We are unable to code sign our Picard.
Basically we seem to have lost our "Developer ID Application" key and have no idea how to retrieve it. We are also not sure if its required or not to sign apps.
We are using Pyinstaller to package Picard.
We tried following https://github.com/pyinstaller/pyinstaller/wiki/Recipe-OSX-Code-Signing
but we get 'error: The specified item could not be found in the keychain.'
when we try codesign --force --verify --verbose --deep --sign 'Developer ID Application: MetaBrainz Foundation Inc.' MusicBrainz\ Picard.app
