Full Disk Access Was On, and macOS Still Refused the App
A Mac app I maintain needs Full Disk Access. It measures disk usage, and most of what is worth measuring sits behind that permission. I switched it on in System Settings ▸ Privacy & Security ▸ Full Disk Access, and the app went on reporting limited access. Its banner said what these banners say: already granted? Relaunch. Relaunching changed nothing, and never could have. The app did not validate…
A Mac app that requires Full Disk Access failed to grant the permission despite being switched on in System Settings. The issue stemmed from the app's signature being out of sync with its nested frameworks. The app was signed with an ad-hoc certificate, while the frameworks were signed with a Developer ID certificate. After a crash caused a stale seal, the app no longer validated the permission requirement. Re-signing the bundle and verifying the app's signature resolved the issue.
