Why does macOS say Storage Studio can't be opened?
Short answer: Storage Studio is signed and notarised by Apple, so this usually means the download is incomplete or altered. Trash that copy and download it again from storagestudio.us rather than overriding the warning.
A properly downloaded copy of Storage Studio is signed and notarised by Apple and opens normally, so this warning almost always means the download is incomplete or was altered on the way.
What to do:
- Move the copy you have to the Trash.
- Download Storage Studio again from storagestudio.us.
- Open the new disk image, drag the app to Applications and open it.
Don't override the warning in System Settings to force a damaged copy open. If a fresh download still won't open, contact support from storagestudio.us with the exact message you see.
