# Is Storage Studio signed and notarised by Apple?

Yes. A properly downloaded Storage Studio is signed and notarised by Apple, so macOS opens it normally. Notarisation means Apple has checked the app for known malicious content before it can be distributed.

Download it only from storagestudio.us. If macOS ever refuses to open it, the download is most likely incomplete or altered in transit — download it again rather than overriding the warning. See [Installing](https://storagestudio.us/install).
