A user on a separate thread said the only way to move files from your Finder into Studio is via an FTP program like FileZilla. Is there a more simple/straight forward way? Dragging and dropping into the UI does not work. I am stuck on this issue and unable to install any modules.
No, you need to unzip the downloaded archive to your PC, connect to your UNA site by FTP and upload the folder of the app to the modules/{vendor}/ folder. For example, the downloaded Timeline should be placed into modules/boonex/ dir.
