Hi Quinn,We are experiencing this exact issue with apps submitted to the Mac App Store. One day, we just started getting support requests from users suddenly getting the "damaged" popup. I assumed it might have to do with an expired certificate, macOS runtime changed in an OS update, or something, so I re-built the app using the latest Xcode/SDK and resubmitted just 2 days ago. The Apple review folks came back with the same popup and rejected the update.What are potential causes of this in otherwise properly built/archived/signed Mac apps?Thanks!Patrick
