Here's the notary log from a recent Invalid submission of the signed .pkg (productsign, Developer ID Installer certificate): "logFormatVersion": 1, "jobId": "5b495af5-1a31-41cd-b8a3-d1e33ab2a12a", "status": "Invalid", "statusSummary": "Archive contains critical validation errors", "statusCode": 4000, "archiveFilename": "Drone_Pad_Signed_v2.pkg", "uploadDate": "2026-08-22T22:40:38.429Z", "sha256": "e5983f8f468af3fc6b11ae9aa819a98544a22a853e459c8eeee6a91385476375", "ticketContents": null, "issues": [ { "severity": "error", "code": null, "path": "Drone_Pad_Signed_v2.pkg", "message": "The binary is not signed with a valid Developer ID certificate.", "docUrl": "https://developer.apple.com/documentation/security/notarizing_macos_software_before_distribution/resolving_common_notarization_issues#3087721", "architecture": null } ] } Submission ID: 5b495af5-1a31-41cd-b8a3-d1e33ab2a12a

But what I have noticed... — a zip containing just the signed VST3 plug-in (signed with my Developer ID Application certificate) was accepted successfully. Submission ID: 5d2ee526-31a7-420b-90da-8f6956ab08e4 — status: Accepted So it seems the issue is isolated to my Developer ID Installer certificate specifically (used to sign the .pkg via productsign) — the Developer ID Application certificate works fine with the notary service. Does that help narrow down what might be misconfigured?

Hello ! The notarization fails and the status displays : Invalid Here Is the screenshot of my latest upload...
