Hi, I'm responsible for generating the macOS installer for Apache NetBeans. Up until today I've not had any issues, the DMG created has never had any issues being used on others machines. The process we have signs and notarizes the app, as expected. However when downloading this from the internet at attempting to install the app, users are reporting that it cannot be opened because it cannot be checked by Apple for malicious software. Heres a link to the app: https://dist.apache.org/repos/dist/dev/netbeans/netbeans-installers/13/Apache-NetBeans-13-bin-macosx.dmg If I try to open this myself(after downloading), I can see 2 messages in Console: 1: assessment denied for Apache-NetBeans-13-bin-macosx.dmg com.apple.message.domain: com.apple.security.assessment.outcome2 com.apple.message.signature2: bundle:UNBUNDLED com.apple.message.signature: denied:no usable signature com.apple.message.signature3: Apache-NetBeans-13-bin-macosx.dmg com.apple.message.signature5: UNKNOWN com.apple.message.signature4: 3 SenderMachUUID: 8702454A-423C-33A4-BDAA-656186E59614 2: assessment denied for Apache NetBeans 13.pkg com.apple.message.domain: com.apple.security.assessment.outcome2 com.apple.message.signature2: bundle:UNBUNDLED com.apple.message.signature3: Apache NetBeans 13.pkg com.apple.message.signature5: UNKNOWN com.apple.message.signature4: 2 com.apple.message.signature: denied:Unnotarized Developer ID SenderMachUUID: 8702454A-423C-33A4-BDAA-656186E59614 I'm struggling to work out how to further diagnose this, to allow us to release this application? The notarization of this app comes back as "Package Approved", so I don't get that reference in those messages. Any help or advice on how to continue with this?
