We’re trying to patch the macOS GOG build of our 2017.4.9f1 game and it fails during the re-signing process. The Steam version patched without issue. If we remove all GOG Galaxy-related libraries from the application then the patching process succeeds, though obviously we can’t actually ship with th…

[image] gumboots: Does anyone happen to know if this will still run, or if the signing needs all bundles present? So if the original build was unsigned, this might be okay. However, macOS really dislikes unsigned apps so it might be better if you signed them. If the application was signed bef…
