Need help signing Install-file, pkg-file for Mac OS X.
Apple account and developer id exists.
Tried signing with following (XXXX is the developer key)
productsign --sign 'Developer ID Installer: XXXX' pkg_path/[url removed, login to view]' 'pkg_path/[url removed, login to view]'
but get error "Could not find appropriate signing identity"
Would pay up to 50 usd for this.
