If you are in the MAC version online, you will find your projects in your creations, entering in your account with your username and password.
Quite the opposite, if you are in the online version of the MAC program, you can find your project, opening Finder / selecting your user / "Library" and on the top right, where it says "search", you should write "Hofmann MP".
Then make the search, but select the option "Library" Not the one "Search this Mac".
Once you find this folder, inside you will have all projects.
When you can not find the library folder, you must go to: Go / go to the folder and write: ~ / Library and click Go.
