Hello Xinyao,
Thank you for your message.
Unfortunately, the
File Transfer connection mode is not available in Viewer for Mac/Linux yet since it's still in the beta stages. Currently, the only connection methods available for Mac/Linux users are
Full Control and
View Only.
However, the File Transfer connection mode as well as other connection modes will be implemented to Viewer for Mac/Linux at the subsequent beta stages or the final release. You can find the full list of features that are already available in Viewer for Mac/Linux on
this page (please see the very first message in the thread). Sorry if this makes our software less useful for you.
Please let us know if you have more questions.
