Getting started · First launch and Full Disk Access
Why does Storage Studio say Full Disk Access stopped working after an update?
Short answer: macOS ties the permission to the exact app copy, so an update can quietly drop it while the switch still looks on. Turn Storage Studio off and on again in Privacy & Security → Full Disk Access.
macOS ties Full Disk Access to the exact copy of the app it was granted to, so updating or repairing Storage Studio can quietly drop the permission even though the switch still looks on. Storage Studio detects this and tells you that's what happened, rather than claiming you never granted it.
To fix it:
- Open System Settings → Privacy & Security → Full Disk Access.
- Turn Storage Studio off, then on again.
- Return to the app — it picks up the change within seconds.
If the message says the permission couldn't be confirmed, your Mac didn't answer in time; Storage Studio treats that as a no to stay safe. Re-checking from Settings → Permissions usually clears it.
